Frequently asked questions
Everything people ask about abcVoiceover, from voice cloning and languages to sharing, downloads and privacy.
Getting started
What is abcVoiceover?
abcVoiceover is a web app for AI voiceover and voice cloning, built around scripts. You set up a project with a cast of voices, each cloned from a short recording, write or paste your script, and generate spoken audio line by line. Each line remembers who reads it and which take you kept, and the whole project downloads as a zip of WAV files.
Who is abcVoiceover for?
Anyone turning a script into voices: audio dramas and podcasts, game dialogue, animation and YouTube videos, and e-learning and explainer videos. It's at its best when a script has several speakers or many lines to keep organized.
How do I get an invite?
abcVoiceover is invite-only during early access. Use the Request an invite button on the home page and tell us a little about what you're making, or ask someone who already uses it for a code. You type the code once, the first time you sign in.
How do I sign in?
With your Google or Microsoft account. abcVoiceover never sees or stores your password, and there's no separate account password to remember. Your projects belong to the account you sign in with.
Do I need to install anything?
No. abcVoiceover runs in your web browser on a computer, tablet or phone. You can record voice samples straight from the browser with your microphone.
Voices and voice cloning
How does voice cloning work in abcVoiceover?
It uses zero-shot voice cloning: the model listens to a short reference recording and speaks new text in that voice. Nothing is trained or fine-tuned, so a new voice is ready as soon as its clip is uploaded, and you can swap the clip at any time. The voice model is the open-source Chatterbox text-to-speech model, run on a server the abcVoiceover team operates.
How long should a voice sample be?
Aim for 5 to 15 seconds of one person speaking clearly, with no music or background noise. The minimum is 3 seconds and the maximum is 10 minutes, but longer isn't better: a clean, well-acted 10 seconds beats a noisy minute. Fast draft mode needs at least 5 seconds. Our guide on how to record a voice sample goes step by step.
What audio formats can I upload?
WAV files, for now. If your recording is an MP3 or another format, convert it to WAV first, or use the Record in browser button, which saves WAV automatically.
Can I clone someone else's voice?
Only with their clear permission. The terms of service allow a voice that's your own, or one whose owner has agreed to it being used this way, and they rule out impersonating, deceiving, scamming or harassing anyone. See using AI voices responsibly.
Can I change a voice after I've used it?
Yes. Replace a voice's clip, rename it or delete it whenever you like. Lines you've already saved keep the take they had, along with the voice and clip that made it, so changing the cast later doesn't change finished work.
Scripts and generating audio
How do I give lines to different characters?
Each script has a main voice, and any line can pick another voice from the project's cast. When you paste a script, start a line with a voice's name and a colon, like Villain: You'll never catch me!, and that line goes to that voice automatically.
Which languages does abcVoiceover support?
23: Arabic, Chinese, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Italian, Japanese, Korean, Malay, Norwegian, Polish, Portuguese, Russian, Spanish, Swahili, Swedish and Turkish. You pick the language per voice. Fast draft mode is English only.
Can I control emotion and delivery?
Yes. Each voice has style presets (Balanced, Expressive, Calm and Fast draft) and a Fine-tune panel with emotion intensity, how closely it follows the clip's pacing, and expressiveness. The reference clip matters too: an energetic recording gives energetic takes.
How long can a line be?
Up to 2,000 characters. Long lines are generated a few sentences at a time and joined into one take, so a full paragraph of narration works. Shorter lines are easier to direct and re-take, though.
What if a take sounds wrong?
Generate another and compare it with the one you have, then keep whichever is better. Every take is also checked automatically: speech recognition listens back to it, and a piece that skips words or runs on past the end of the line is made again before you hear it.
Do I have to keep the page open while it generates?
No. Generating goes through a queue. Press Generate on one line, or generate every new line in a script at once, and the takes are made in the background, in order, even if you leave the page.
Sharing, downloads and privacy
Can I work on a project with other people?
Yes. Share a project with someone's account ID and choose whether they can view it (listen and download) or edit it (change its scripts, voices and lines). Everyone who can see a project can talk it over in its comments.
What do I get when I download a project?
A zip with each voice's clip and a folder per script: the script as text, a CSV of every line and who reads it, and each line's kept take as a WAV file, numbered in script order, ready to drop into an audio editor, a video timeline or a game engine.
Who owns the audio I make?
You do. The terms of service say the scripts you write, the recordings you upload and the audio you generate are yours. You're responsible for having the right to use what you upload, and for how you use what you make.
Is my voice data used to train AI?
No. Your recordings and scripts go only to the voice server the abcVoiceover team runs, to make your takes. They aren't sent to an outside AI company and aren't used to train models. The privacy policy has the details.
Can I delete my account and everything in it?
Yes, yourself, from the Account page. It deletes your projects and their audio and takes you out of projects shared with you. Download everything first if you want to keep a copy: the Account page has a Download everything button too.
