Voice library

Create a voice from recordings, manage reference clips, and build or refine voice profiles. Record only voices you own or have permission to use.

Add this person’s clips

Record or upload 1–5 clean WAV samples (10–30 seconds, only this speaker) so Studio can identify their voice in videos. Then upload videos to extract and filter that speaker’s clips.

Use clear speech without other speakers. Up to five samples per person.
Files stay on this computer. Supported video/audio files; 8 GB maximum per file.

Saved voice samples

Voice capture

LOCAL MIC INPUT

Read at a comfortable pace in a quiet room. Each take is converted to WAV in your browser, previewed, then saved on this computer as a voice sample. Four original prompts help capture varied sounds and delivery.

00:00
Choose a prompt and record 10–30 seconds. At least one clear sample is required; using three or more prompts is recommended.

Finding available datasets and clips…
Choose a clean clip, ideally 7–15 seconds, with the delivery you want.
More clips take longer; 400 is usually enough.
0.65
For prepared datasets, clips below this target-speaker match score are excluded.
1.00
1 uses the full dataset identity; lower values blend more of the anchor voice back in.

Review reference clips

Review one clip at a time. Delete removes the source clip, Keep saves your decision without promoting it, and Promote adds it to this person’s active six in place of the weakest reference. Prepared datasets use their speaker-match scores; folders use audio quality.

Compare profiles

Build a candidate, then generate both profiles from the same short script, settings, and seed. Listen before adopting it.
