Voice Design

Describe the speaker via attributes — gender, age, pitch, accent, dialect, whisper.

Describe the speaker via attributes — no reference audio needed.

Tips

• Case-insensitive — Male, MALE, male are equivalent.
• Mix English + Chinese — auto-normalised internally.
• Less is more — if a combination behaves oddly, simplify.

See the upstream voice-design reference for the canonical attribute table.
