Step 1: Open the custom voice creator
You can start from any of these places:
My Videos → My voices → Add +New voice
New character (or editing existing character) → Voice dropdown → Create new voice
Script creation → Narrator dropdown → Create a new voice
Step 2: Choose how you’ll add audio
Option A: Record your voice
Click Record (or the microphone icon).
Speak naturally — or imitate a different voice! — or at least 15 seconds.
Aim for more seconds if you can. More data usually means better quality.
When you’re done, click the red button.
Listen to the preview.
If you’re not happy with the audio, choose Record again and try again.
When you like the recording,
name your voice (it will default to My Voice)
click Create voice.
Option B: Upload a recording
Click Upload.
Select an audio file from your device.
Must be .wav or .mp4 file
Must be less than 10MB
Make sure the file:
Contains only one voice.
Has minimal background noise or music.
Is at least 15 seconds long.
Wait for the upload to finish, then click Next.
Listen to the preview.
If you’re not happy with the audio, choose Record again and try again.
When you like the recording,
name your voice (it will default to My Voice)
click Create voice.
Step 3: Review your custom voice
After processing, you’ll get a preview of the generated voice:
Click Play to listen.
If the result doesn’t sound right:
Go back and record or upload a new sample.
If you’re happy with it, name your voice and click Create voice.
⚠️ Important:
Once you click Create voice, you cannot:
Re-record the base audio
Upload a new file for that same voice
Rename the voice
If you need to change it later, you’ll have to delete the voice and create a new one.
Step 4: Use your custom voice
Once saved, your custom voice will be available:
In the Voices section of My Videos
In the Voice dropdown for characters
In the Narrator voice options in the script/editor
You’re now ready to use your custom voice in any new video!
