Step by step
How to convert text to speech with Voice Labs
The whole thing takes about a minute, and step three is optional.
-
Paste or type your text
Open Voice Labs and enter up to 5,000 characters. A counter under the text shows how much room is left.
-
Choose a voice
Open the library of 370+ voices, filter by language and tap Preview to hear each one before you choose.
-
Adjust the delivery (optional)
Open Voice Settings to change stability, similarity and speed, or pick the Natural, Narration or Expressive preset.
-
Tap Generate
The audio is ready in seconds and starts playing with the text highlighted line by line.
-
Save or share
Save the audio to your device or share it straight to another app, such as your video editor.
Follow along
Your text lights up as the voice speaks
Voice Labs plays every generation with its text in sync, like live lyrics. You always know where you are in the script, which makes checking a long voiceover quick.
- The line being read is highlighted
- Each word lights up as the voice reaches it
- Tap any line to jump there and play from that point
- Saved items in History play back with the same synced text
Long scripts
Room for up to 5,000 characters
One generation holds roughly 800 English words, which is about five minutes of speech at a natural pace. That covers a full short-form video script, a product explainer or a chapter of a bedtime story in one go.
For anything longer, split the script at a natural break, such as a scene or section heading, and generate the parts one after another with the same voice and settings.
Voices
Pick the voice that fits the script
A meditation script, a product ad and a cartoon villain should not sound alike. The library has 370+ voices across 31 languages, each with a short description and a Preview button, so you can audition a voice before you use it.
Save and share
Out of the app and into your project
Save the audio to your device or share it directly to another app. Everything you generate is also kept in History, where you can search for it, replay it and share it again.
- Save audio or share it to other apps
- Search past generations in History
- Separate tabs for speech and voice changes

All use casesWriting for an AI voice is its own small skill. How to write scripts that sound natural
How do I turn text into speech with Voice Labs?
Open the app, paste or type your text (up to 5,000 characters), choose a voice, and tap Generate. The audio plays back with the text highlighted line by line, and you can then save the file or share it to another app.
How long can my script be?
Each generation can be up to 5,000 characters, which is roughly 750 to 850 English words or about five to six minutes of speech at a natural pace. For longer pieces, split the script into sections and generate them one after another.
What does “follow along” mean?
While a generation plays, the line being read is highlighted and each word lights up as the voice reaches it, like live lyrics. Tap any line to jump to it and play from there. Saved items in History play back with the same synced text.
Do the voices sound natural?
Yes. The voices are generated by AI speech models rather than stitched together from recordings, so they have natural rhythm and intonation. Every voice has a Preview button in the app, so you can listen before you spend a generation on it.
Does Voice Labs work offline?
Generating audio needs an internet connection, because the AI voices run on servers rather than on your phone.
Can Voice Labs read PDFs, web pages or books aloud?
Voice Labs is a voiceover maker rather than a document reader: you paste or type the text you want spoken. If you mainly want to listen to PDFs, e-books and web articles, a reading app such as Speechify, ElevenReader or NaturalReader is a better fit.
Is Voice Labs free?
Voice Labs is free to download and your first 2 generations are free. After that, and to use Voice Changer, you choose a weekly Starter, Pro or Advanced plan.
