Voices, Text to Speech, Speech to Text, Sound Cleaning and your assets.
Voices
- Browse the voice libraryOpen the voice library, read what a voice row tells you, hear a preview, send a voice to Text to Speech and put it on an agent.
- Filters, previews and favouritesNarrow the voice library by search, dialect and voice traits, use the preview player, and keep a list of saved voices that follows you into every picker.
- DialectsThe dialects the voice library carries, how the library groups voices by them, what a dialect changes in generated speech and in an agent, and how to pick one for a region.
- Choosing a voiceHow a voice for narration differs from a voice for an agent, what to listen for in a preview, and which speech settings matter for each use.
