Free AI Voice Generator
Turn text to speech with lifelike voiceovers from HeyGen Voice, the #1 ranked AI voice model. Clone your voice from 60 seconds or pick a library voice, then download audio or a full video.

High-quality AI voice technology, built for video
Powered by HeyGen Voice, the #1 voice model
Every read runs on HeyGen Voice, ranked first on Artificial Analysis' voice leaderboard. In blind tests, listeners picked it over leading text-to-speech models for similarity. The power of AI here: generated voices with natural nuance, for ads, lessons, or an AI podcast generator episode.

Tone control with Voice Director
Flat reads lose viewers. Pick one of eight Voice Director tones, from Calm to Excited, or type your own direction. Then set Expressiveness Boost on one slider: low for training, high for AI video ads, zero for the baseline read.

Voice cloning from a 60-second recording
Record 60 seconds on any phone and HeyGen Voice learns your timbre, accent, and phrasing while dropping background noise. Set similarity from 1 (adapts to the scene) to 4 (sounds exactly like you), or go deeper with AI voice cloning.

Design a new voice from a text prompt
Describe the voice you want and HeyGen generates it. Start with age, accent, and gender, then add tone. A prompt like "a wise old wizard with a calm, measured tone" creates character voices for games, cartoons, and branded content.

Your own voice in multiple languages
The same recording reads Spanish, German, French, or Chinese with a native accent, chosen as narrator in 77.4% of cross-language votes. Dub into 177+ languages and dialects with AI dubbing, and lip-sync on screen with the AI video translator.

Scene-aware voice, built for video
A studio read sounds wrong on a beach shot. Inside a HeyGen video, HeyGen Voice matches room and mic distance, with sliders for pitch variation and background level. Finish in the AI video editor with music and auto-captions.

Use cases for AI voiceovers

YouTube, TikTok, and Reels voiceovers
Faceless creators lose hours to retakes. Clone your voice once, add the script, and get a voiceover for YouTube or Reels that fits the shot, so social media content ships the same day.

E-learning and course narration
Across 245 lesson scripts in five languages, testers chose HeyGen Voice to narrate full lessons and rated it highest for clarity and native accent. Add subtitles with the subtitle generator for accessibility.

Audiobooks and storytelling
Hiring narrators is slow and DIY audio production rarely lands. Train a Professional Voice on 20+ minutes of your recordings, then generate each book chapter by chapter in your own voice.

Podcasts, ads, and dialogue
Skip the paid voice actor for podcasts, intros, and sponsor spots. Use Full Clone to sound exactly like your session, and assign a voice per scene in AI Studio for two-host formats.

Marketing videos and product demos
Every campaign and region needs a polished read. Pick an Excited tone for launch energy, localize the script, and pair it with a product demo video so launches go live the same week.

Multilingual training and onboarding
Global teams need one trainer voice in every language. Record once and HeyGen Voice reads Spanish, German, French, or Chinese in that voice, building a training library without a recording booth.

FAQ: frequently asked questions
What is an AI voice generator and how does it work?
AI voice generators are TTS, or text-to-speech, tools that turn written text into spoken audio. Artificial intelligence and machine learning models trained on human speech produce human-like speech with natural pacing. Paste a script, choose or clone a voice, and generate.
How realistic are HeyGen's AI voices?
HeyGen Voice is ranked #1 on Artificial Analysis' voice leaderboard, and blind-test listeners picked it over leading models for similarity and narration. Anton Voroniuk's case study shows 1M+ students reached with AI voices in his courses.
How do I create a voiceover with HeyGen?
Write the script, then clone your voice, design one from a prompt, or pick a library voice in the language you want. Choose a tone, preview for free, and generate. Pair the AI voiceover with an AI spokesperson or download the audio.
Can I use AI voiceovers for commercial projects?
Yes. Use AI generated audio from HeyGen for YouTube videos, ads, courses, PPT to video, audiobooks, and client work, as long as your script and cloned voices follow HeyGen's usage guidelines. Only clone voices you own or have permission to use.
Is the AI voice generator free?
Yes. HeyGen Voice comes with every HeyGen video at no extra cost. The free plan needs no credit card and includes 3 videos a month up to 1 minute each, 1 voice clone, and free previews. Free users see a watermark on exports.
How does voice cloning work?
HeyGen Voice learns your timbre, accent, and phrasing from a 60-second recording. Voice Clone adapts to each scene and Full Clone matches your recording exactly. A professional clone trains on 20+ minutes of audio. Free plans include 1 clone, Creator 40, Pro 70.
Which languages and accents does HeyGen support?
Library voices span many languages, from Hungarian, Ukrainian, Catalan, and Estonian to Galician, Azerbaijani, Javanese, Gujarati, and Malayalam, filtered by region and accent. A HeyGen Voice clone reads Spanish, German, French, or Chinese in your voice.
Can I control emotion, speed, pitch, and pronunciation?
Yes. Voice Director offers eight tones plus custom direction, and Expressiveness Boost runs from baseline to full energy. Speed and volume sit in AI Studio, pitch variation is a scene slider, and you can respell tricky names phonetically.
Why do some AI voices sound robotic?
Usually the script or sample is the cause, not the AI speech model. Write short sentences in natural language and use punctuation for pauses. For clones, record in a quiet room with the mic 6 to 8 inches away.
Is there a character limit per generation?
The editor splits long scripts into segments of up to 1,000 characters, so you can build long narration scene by scene. The free plan caps videos at 1 minute. The HeyGen Voice API bills per character with no minimums.
What's the best AI voice generator for creators and teams?
It depends on how you publish. HeyGen Voice ranks #1 on Artificial Analysis' leaderboard and is the first voice model built for video, paired with avatars, AI lip sync, and an editor. A standalone speech generator stops at the audio file.
Can I translate and dub my voiceover into other languages?
Yes. Use the Translate button in voice settings, or dub a finished video into 177+ languages and dialects in your own voice. Würth Group shipped a 65-minute presentation in eight languages in four days, cutting translation costs by 80%.
Can I pair the voice with an AI avatar or video?
Yes. Send your voice to an AI avatar that lip-syncs on screen, or build the video around it in AI Studio. HeyGen Voice matches the scene acoustics, so you get perfect audio for the room, not standard audio from a booth.
Is there an API for AI voice generation?
Yes. The HeyGen Voice API costs $30 per 1M characters with no minimums or tiers. Send a voice ID, text, and language to get a WAV file URL, or stream audio over SSE with word timestamps for captions.
Is my script and generated audio kept private?
HeyGen is SOC 2 Type II certified and GDPR and CCPA compliant, with AES-256 encryption at rest. Enterprise data is excluded from model training by default, and other users can opt out in settings.
Can I generate AI voices in my browser or on mobile?
Yes. HeyGen runs in any modern browser with no install. Sign up free, type your text, and generate realistic voices like your own. The same workflow works in the HeyGen mobile app.
