The 9 best AI voice generators in 2025

Recording a voiceover is challenging enough. You go through way too many takes to get what you want. You don't have enough time to rehearse and hit your tone and intention targets. You read endless audio editing software guides to make sure your voice sounds good. And even if you nail all of these things, if you don't have access to a studio, your perfect performance will be riddled with background noise.

So should you give up and hire a voice actor? Not yet: AI voice generators can deliver impressive results. These AI text-to-speech apps have been picking up on quality, realism, and controls, helping you create a natural rendition of text without even having to plug a mic into your computer.

I spent a few weeks testing all the AI voice generator tools I could get my hands on, and based on my experiences with them, these are the nine best.

The best AI voice generators

• ElevenLabs for an all-in-one voice and sound creation platform

• Hume for designing a voice from a prompt

• Speechify for human-like cadence

• WellSaid for word-by-word control

• DupDub for multilingual phoneme-level control

• Respeecher for engaging speech variations

• Altered for advanced creation and editing controls

• Murf for emphasis control

• TTSMaker for a free AI voice generator

What makes the best AI voice generator?

The best AI voice generators are pretty easy to spot: the generated speech sounds natural and realistic, almost (almost!) as if a real person is saying the words.

Beyond this intuitive check, each platform offers a range of settings that help you steer the generation, such as pronunciation, pitch, volume, or pace. And if you're planning to go full AI voice, you can learn Speech Synthesis Markup Language (SSML) and mark how each word should be performed with the highest level of control. Don't overdo these, though: it can reduce the quality and realism of the output.

With that in mind, here's what I looked for as I was testing the best AI voice generators:

• Realism. These text-to-voice apps offer realistic speech, with variations, natural changes in tone, and adequate pauses.

• Available controls. Pitch, volume, pace, and pronunciation controls, among others, will let you tune the generation to your needs.

• Audio quality. I looked for the highest export audio quality possible, so you can use these voices in any project.

• Voice library. Multiple voices can fit a wider range of projects—including voices in other languages—so you can have greater flexibility as you work.

• Extras. If any app has any useful extra tools for generating voice, such as audio-to-audio or AI model training, I took that into consideration. But I didn't consider any AI video generation apps for this list, even though some do offer text-to-voice as an add-on.

I also went a little further. Before becoming a writer, I was an actor for ten years, and back in the day, I did a one-month workshop on voice acting and dubbing. I used that experience to judge these voices based on additional parameters:

• Narration pacing. Humans make variations in reading speed, which is useful for adding emphasis or increasing engagement. Bad AI usually evens everything out, so I paid attention to the models that introduced the best variations.

• Intonation. Intonation deals with the variations of pitch throughout sentences. The worst AI models make everything predictable, robotic, and lifeless—many were excluded because of this.

• Emotional performance. Some apps let you choose sad, excited, or whispered renditions of the text. I excluded those that weren't subtle, heavily over- or under-acting the script. Still, it's hard for AI to give an accurate performance here, so if you need something nuanced, you might consider working with a professional voice actor.

I spent over three weeks signing up for every AI voice generator I could find. I used the same text in every one of them to better home in on the differences. I tried the controls to gauge their power and see whether they'd help me improve the final result.

When judging the best AI voice generator for your purposes, keep in mind that your audience will probably be paying attention to other details of your content as well. A few imperfections here and there are completely forgivable. With all this in mind, here are this year's best picks.

The best AI voice generators at a glance

Best AI voice generator for an all-in-one voice and sound creation platform

ElevenLabs (Web, iOS, Android)

ElevenLabs pros:

• Life-like voices

• Large voice library spanning multiple languages

ElevenLabs cons:

• Occasional output inconsistencies, especially when generating sound effects

ElevenLabs used last year's funding round to expand the feature set from a simple, high-quality voice generator to a platform that can cover most of your voice, sound effects, and soundtrack generation needs. This makes it a great pick if you're looking to consolidate your audio creation workflow into one AI-powered browser tab.

The platform is expanding fast; some entry points to interesting features can be a bit hidden. To start, you'll find the core features front-and-center: instant speech for the typical text-to-voice experience, along with the audiobook tool, music generator, and sound effects suite. There's voice design, digital voice cloning, and a deep curated library of AI voices that you can use in these projects. Other features tucked away include podcast-style generation, video to music (a background music generator), or creating a voiceover for a video.

When you click to start any of these, you're taken to the Studio interface. It changes slightly depending on what you're doing: it always has the core controls for voice, with stability, volume, and style exaggeration (among others). For example, when voicing an audiobook, you get chapter controls and slightly deeper multi-voice settings; when dubbing a video, you get a pane to see the frames as you generate the voice.

Beyond this rich toolset, the v3 alpha model is an exciting addition, introducing action, tone, and emotion direction. You can now add directions in square brackets anywhere in the script to control the model's performance, adding sarcasm, a chuckle, or a whispered section. This is only possible with the newest model, so make sure you select it from the dropdown menu on the right. As advertised, the results can vary a lot and require more prompt engineering, but the performance feels more unpredictable, which makes it feel more alive when compared with the previous models.

The ribbon around this versatile feature set is the conversational agent builder. If you want to give a combination of shine and automation to your customer support experience, ElevenLabs can put its high-quality voices in your website widgets and phone lines. There are deep controls for training agents with your company data so they can respond accurately, and a workflow builder to set multi-agent frameworks so each can answer a different set of questions. To improve integration, you can set up tool use so the agents can interface automatically with your internal systems, updating orders, retrieving service status, or escalating to a human as needed.

For teams looking to automate further, ElevenLabs built a Zapier integration, connecting it to thousands of other apps you use at work and helping you weave AI voice generation into broader production processes. For example, Zapier can take a finalized script from Google Docs, send it to ElevenLabs to generate narration, and upload the audio file to Dropbox. Get started with a pre-made template.

ElevenLabs price: Free plan available for 10 minutes of high-quality text-to-speech and 15 minutes of conversational AI. Starter plan at $5/month adds commercial license, unlocks most platform features, and adds 30 minutes of text-to-speech and 50 minutes of conversational AI.

Best AI voice generator for designing a voice from a prompt

Hume (Web, iOS)

Hume pros:

• Real-time, emotionally-aware conversation support

• Tight privacy controls available, including zero-data retention

Hume cons:

• Limited multi-language support: only English and Spanish

Scrolling through hundreds of preset voices and still can't find one that fits your brand perfectly? Most platforms give you plenty of options, but sometimes you need a voice you've never heard before, unique and impactful. Hume lets you design exactly that voice from scratch using nothing but a text prompt.

Describing a voice in words feels impossible at first. After all, why does Morgan Freeman sound like a divine figure? Hume has a clever shortcut: open the voice creation tool, and hit the auto-generate button for a starter prompt. From there, choosing an accent feels like the most powerful setting here: switch from "British" to "Nashville twang," and you're completely shifting the rhythm and musicality. Then, finish by layering descriptors like "deep and resonant" or "bright and energetic" to fine-tune the pitch and pacing.

Once you've designed your custom voices, create a project, paste your text, pick your voice, and generate. Don't expect the granular word-by-word controls you'll find in other platforms. Instead, like when designing a voice, you can control the performance with a text prompt. This has a learning curve and unpredictable results, but can yield more nuanced performances as you gain more experience.

Beyond voice generation, Hume has something no other platform offers: emotional intelligence. Set up a conversational agent and you'll see emotion scores for excitement, sadness, confusion, and more. The dedicated system can measure emotions in your voice on a 0 to 1 scale: as you test your agent, you can see values such as "Determination: 0.21," "Joy: 0.19," or "Excitement: 0.39." These signals are fed as inputs into the voice generation engine, helping tune the vocal performance to mirror, match, and vibe with the user.

Even wilder: there's facial analysis that detects your mood from your camera and adjusts the conversation in real time. It's experimental, feels like sci-fi, and is reasonably accurate: I've noticed that I may not be the best judge of the meaning of my facial expressions. Most of this lives behind API access, so unless you're building an app or integrating voice into a product, you'll mostly stick to the basic conversational features. Still, it's a glimpse into where AI voice is heading.

Hume price: Free plan available for around 10 minutes of text-to-speech per month. Starter at $3/month offers around 30 minutes of text-to-speech and the ability to create and have up to 20 projects.

Best AI voice generator for human-like cadence

Speechify (Web, iOS, Android)

Speechify pros:

• Includes tools to build videos and presentations

• Easy to generate audio for multiple AI voices in a single project

Speechify cons:

• Output quality in terms of emotion and tone varies depending on which voice you choose

Cadence: the rhythm as someone reads a text, the spaces between words, and the overall speed. Speechify is ahead of the competition, generating a pleasing output in one shot that sounds like a creative, experienced voice actor. Calm, well-paced, with a good balance between variation and consistency.

The website's home page may be confusing as Speechify brands itself as a platform for reading text out loud, mostly for productivity use cases. You can use it while you drive or take a walk outside. And with available voices such as Snoop Dogg and Gwyneth Paltrow, it's fun to listen to a list of your favorite digital marketing blogs in the legendary style of the D-O-double-G.

If you want to generate and download voices for your projects instead, click the button at the top of the screen to go to Speechify Studio. While you can't use the famous voices—boo—you'll see that the existing options are top-notch. As you paste your script and start generating, you can increase or decrease speed, control pitch, change the volume, add custom pronunciation, and set pauses at different parts of the text.

There are two good extras here. If you usually create slide-based videos, Speechify has a tool that can put together a simple presentation. Just generate the voice, add a background music track, and export. The second one will let you add your voice to the platform, so you can generate sound using your own voice.

Speechify price: Free plan offers 600 monthly studio credits and access to over 1,000 voices. Studio Starter plan at $11.58/month adds 7,200 studio credits, access to licensed soundtracks, stock media, and commercial use.

Best AI voice generator for pronunciation and timing control

WellSaid (Web)

WellSaid pros:

• SOC 2 and GDPR compliance

• Integrates natively with Adobe Premiere Pro and Express

WellSaid cons:

• Struggles a bit with emotional performance, with limited controls

When you need to control exactly how a word sounds and how each lands as sentences unfold, say it well with WellSaid. It offers word-for-word controls to make sure you're hitting all the right notes consistently.

How does this work? Open the editor, and paste in your script. On the right-side tab, click Cues to open the controls. The words on the screen become outlined: click on the word or combination of words to select, and then adjust loudness or pace. If you select a comma or a period instead, you can adjust how long the pause should be.

When you're finished editing one section, click anywhere on the central part of the screen to deselect it. You'll notice that what you just edited is now underlined with color: if you changed pace, it's green; if you edited loudness, it's blue; for punctuation pauses, it's purple. This is a good guide in case you want to come back and make adjustments. One word of advice: don't make drastic changes—the biggest variations here can reduce the overall realism.

Pronunciation controls don't live in the generation editor. Instead, look to the left-side menu, click Replacements, and start adding them in. Start by adding the original word, and then type out how it should sound instead—even if it butchers the spelling. There's a learning curve and experimentation process around this, so make sure to take a look at the respelling guide.

To make the most of the tools here, there's a Resources section with entry points to the most important topics in the documentation. There are step-by-step guides to help you get started, improving your voice generation workflow or working with pronunciations. And if you're collaborating with others, you can quickly share a link to a project to gather feedback.

WellSaid Labs price: Free 7-day trial without downloads. Creative plan at $50/user/month offers 60 downloads and all English voices.

Best AI voice generator for multilingual phoneme-level control

DupDub (Web, iOS, Android)

DupDub pros:

• All-in-one workflow for script, voice, and video

• Over 750 voices available in 1,000 styles and 90 languages

DupDub cons:

• Mobile app doesn't have a lot of features

When your script is packed with technical jargon, foreign brand names, or industry acronyms, most AI voice generators will butcher the pronunciation. This forces you to do some mental gymnastics: spelling words like "fyoo-chur-is-tik" to get "futuristic" to sound right. DupDub doesn't remove this step, but it vastly increases the accuracy thanks to its phoneme-level controls, making sure your effort is well spent.

Here's how to get the perfect pronunciation: highlight any problematic word in your script, and click the Phoneme button at the top. An on-screen phonetic keyboard appears, so you can type in exactly what you're looking for phoneme by phoneme. No more creative respelling required. You can now generate "Xiaomi," "PostgreSQL," or "Kubernetes" without hilarious/disappointing mishaps.

The interface gives you control over nearly everything from basic pitch and rhythm, to speed both on a general and section-by-section level. You can set acronyms to be said as a word ("API") or by its individual letters ("A-P-I"). Punctuation and paragraphs have granular timing controls too: in fact, don't forget to dial down those comma pauses from the jarring 200ms default to something more natural around 50-80ms.

This precision extends across the library of 750+ voices in 90 languages. You get the same phoneme-level control whether you're tackling technical terms in English or brand names in Mandarin. The voices won't match ElevenLabs' natural realism, but if pronunciation accuracy trumps perfect inflection, DupDub's granular controls make it worth the trade-off.

DupDub goes beyond voice generation with an all-in-one content workflow. Start with just an idea, generate your script with AI, create the voiceover using those phoneme controls, then pull everything into the built-in video editor. It's a solid choice if you want to eliminate tool-switching for simple projects, though you'll want dedicated video software for anything complex.

DupDub price: Free 3-day trial with 10 credits. Personal plan at $11/month offers 150 credits per month. Pay-as-you-go plan available.

Best AI voice generator for engaging speech variations

Respeecher (Web)

Respeecher pros:

• Used in the Star Wars franchise to restore Darth Vader's voice

• Integrates with Avid Pro Tools

Respeecher cons:

• The standard US-English baseline can be too strong when working with other accents

Tired of hearing robotic speech that sounds like a long, boring straight line? Respeecher introduces variations that make the narration more interesting to hear, increasing how natural and realistic each voice sounds.

The best part is you don't have to engineer this at all. When you input your text, you can try generating it with different voices or narration styles. Each generation will be grouped under the appropriate part of the script, with natural-sounding variations.

The user interface is unintuitive, so it was a surprise to find generation controls hidden away from the main editor screen. Click the Settings tab on the left side, and tweak pitch calibration, emotional range, and general audio properties. When you change these, it changes all future outputs, so remember to come back here if you need something different.

In addition to pasting in your text or uploading an audio file, you can use your microphone to record it live. In this case, all the app does is change your voice to match the template's, giving you full control over the performance of the text. If you have some acting experience or have natural talents here, be sure to give it a try.

You can train an AI model with your own voice or the voices of others, so you can play an entire cast of characters using your keyboard. As this could make deepfakes easier to produce, Respeecher runs a security check to understand who you are, also raising the monthly subscription price sharply.

I tried multiple voices with the same text, and there's a more creative vibe here when compared with others on this list. This enunciation and voice style is a good match for cartoons and quirkier projects. This doesn't mean it's off-limits for serious business use, but it could turn off people looking for a more professional-sounding avatar. A drawback or an opportunity to differentiate from your competition? Up to you to judge.

Respeecher price: Free 3-day trial, offering 100 text-to-speech requests per day. TTS Only plan at $1.60/month adds 30k characters per month, with a range of 25 voices and 50 narration styles to choose from. Pay-as-you-go also available.

Best AI voice generator for advanced creation and editing controls

Altered (Web, Desktop)

Altered pros:

• Can run online or locally for better privacy and performance

• Wide range of narration styles available

Altered cons:

• Output requires some editing before it's ready to use

If you need more than basic text-to-speech generation, Altered delivers the most comprehensive toolkit for voice creation and audio editing. It'll take you a bit longer to get familiar with all the corners, but let's take a walk through what you can do.

Real-time morphing enables the Altered Virtual Microphone, changing your original voice to that of an AI avatar in real time. A fun thing to do when you're 14 and chatting online with your gamer friends, but business-oriented grown-ups can use it to record this voice directly into another audio editing app, streamlining the workflow.

Post-production morphing is a fancy name for audio-to-audio generation. Add a recording of a text, choose the target voice, and hit generate. Download the results, and plug them into your project.

Rapid voice creation lets you add clean 4- to 8-second clips of a voice to the platform, so you can clone it and use it for generation. (Terms and conditions apply.)

Text-to-speech opens the expected editor to input your script and select your voice. Narration styles depend on the one you choose, so click through each to see the main differences. The possibilities here vary between "Just Below Neutral" for consistency to "Positive, Shout" for emphasis and energy. Mind that, depending on the script and the tone you choose, the results may be inconsistent, strange, funny, or all of the above.

Finally, Altered also packs an advanced Voice Editor with a cool amount of controls. You can upload your audio—any kind of audio—and access transcription, speech generation, or noise removal, among many other possibilities. The learning curve is a bit steep here, as this screen has a real audio editor vibe: be sure to open the docs and use them as a companion.

Altered price: Free plan available for 3 minutes per month of voice morphine, 10k AI tokens, and local voice cloning. Creator plan at $30/month adds 60 minutes of voice morphing and 325k AI tokens.

Best AI voice generator for emphasis control

Murf (Web)

Murf pros:

• Dubbing and translation available

• Direct integration with Canva to add voice to designs or presentations

Murf cons:

• Only a group of voices in the library sound good, with many others still sounding robotic

Try this simple beginner acting exercise: pick a sentence from this article, and read it out loud. Then repeat it emphasizing a different word each time. As you do, notice how the meaning and feel of the whole sentence changes. Murf lets you do this for your AI-generated voices.

The emphasis control button is easy to miss. When working on a project, start adding text to the first block. While you're doing that, take a look at the icon to the left of the play button—it looks like a comment icon—and click on it. A pop-up appears with a sequence of all the words in that block, with a high-medium-low scale: click anywhere to add a point. Where you click matters, so experiment with adding points in the left/right and top/bottom axes.

Beyond these controls, you can adjust general speed and pitch, add pauses, or add custom pronunciation. If you choose the Ken voice, you'll also have access to the widest range of narrative styles, a total of nine, from Storytelling to Sad. I tried the Sobbing setting, expecting a bad result, but was surprised by the subtle acting. Good one, Ken.

When you look at the bottom of the screen, you can expand the timeline to reveal more features. You can add video and music directly into the platform to produce content and export it directly from Murf, ready to share. As you move your content strategy forward, you can invite your teammates and collaborate on voice generation projects: anyone can leave comments on each script block, so you can keep tweaking until you reach the best result possible.

When working as a team, you might have to move data between apps. Murf now integrates with Zapier so you can make this process seamless and automated. Get started with a pre-made template, or build entire automated systems from scratch.

One last word of advice: the voices on the paid plan sound much better than the ones on the free tier. If you're serious about voice generation and like Murf's controls, consider investing sooner.

Murf price: Free for 10 projects and 10 minutes of voice generation. Creator plan at $19/month increases the limits to 100 projects and 2 hours of voice generation.

Best free AI voice generator

TTSMaker (Web)

TTSMaker pros:

• Commercial use allowed even for free voices

• More than 600 voices across 100 languages, with 20 available for free without limits

TTSMaker cons:

• Output quality isn't as good as others on this list

TTSMaker delivers unlimited voice generation on select voices with zero hidden costs. It's not the flashiest platform on this list, but if you're working on a budget or testing out AI voice for the first time, it gets the job done without asking for your credit card.

Here's how it works: pick from the 20 voices marked "unlimited," and generate as much audio as you want—the remaining voices come with a 20,000-character weekly limit. The interface feels basic compared to ElevenLabs or Speechify, but don't let that fool you. Click Settings, and you'll find useful controls like voice speed adjustment, pitch tweaks, and paragraph pause timing. You can even upload background music to layer directly into your generation, which is a nice touch for a free tool.

Beyond the standard MP3 format, you can download your audio as OGG, AAC, OPUS, or WAV files, depending on your project needs. Even better, the platform generates an SRT subtitle file alongside your audio: a surprisingly useful feature that lets you embed synchronized captions directly into your videos without additional transcription work. For content creators juggling tight deadlines, this subtitle export alone can save hours of manual captioning.

The voice quality won't win any awards, but it's decent for quick projects. While it can sound a bit artificial from time to time, it's clear and intelligible, perfect for explainer videos, internal training materials, or social media content where the voice supports rather than stars.

One critical heads-up: TTSMaker only stores your files for 30 minutes before deleting them. Download immediately after generating, or you'll be starting over. With over 600 voices across 100+ languages and genuine commercial use permission, it's hard to complain about a tool that costs nothing and delivers consistent results.

TTSMaker price: Free for unlimited voices (20 available) and 20,000 characters/week for premium voices; Lite plan at $9.99/month unlocks 300,000 characters monthly.

Does OpenAI have an AI voice generation model?

Yes, the creators of ChatGPT are in the game. The only way to use the OpenAI text-to-speech is via API, requiring a bit of tech-savvy to set this up.

They also have an AI voice cloning model that's reportedly so powerful that it's not available for general use. (Yikes.) There's no estimate as to when a commercial version will pop up. Read more in the official blog post on the challenges and opportunities of synthetic voices.

Are AI-generated voices legal?

All the platforms on this list offer a collection of voices that were created by fine-tuning the training data or modeling a real person's voice with their consent. Using these voices is legal, provided you remain within the service and licensing terms of the app you're using.

The main problem lies with AI voice cloning. With just a few samples of a real person's voice, anyone could tune an AI model to talk like anyone—including famous people. And including you. Creating and using these deepfakes can lead to identity theft, manipulation, misinformation, blackmail, or infringement of copyright laws (when talking about artists and their work).

Depending on where you are in the world, there may be legislation to control these kinds of uses, meaning there are legal consequences if consent isn't secured or if the voice is used with criminal intent—or in a way that can be interpreted as such. If you're cloning someone else's voice and using it to generate with AI, always secure their (preferably written) consent before using the outputs.

Speaking without a mouth

With an AI voice generator, you can turn scripts into a flowing narrative, ready to add as a voiceover on a video, without dozens of takes and without hiring a production team.

All the platforms on this list offer ways to try out the features and voices, so pick one of your scripts and run your tests. It's also important to find one that has controls that make sense to you, so take some time to feel how each one works. Now that you can speak using just your keyboard, what will you create next?
