Language
Each agent has a Language dropdown in the conversation settings sidebar. Pick the language, then assign a voice in that same language. Mismatched voice/language pairs cause noticeable pronunciation problems. Thoughtly supports 36 languages. If you need a language that is not listed in the dropdown, contact support. To serve callers in multiple languages, create a separate agent per language with matching voice and Genius knowledge base.Speed (Cartesia)
Cartesia voices have a Voice Speed slider in the Presence section of the Agent Builder sidebar. The slider runs from 0 (slowest) to 100 (fastest), with 50 as the default. Small adjustments of 10 points are noticeable. The slider is disabled when a non-Cartesia voice is active.Volume (Coming Soon)
A volume slider for Cartesia voices is in development and will appear alongside the speed control in Presence settings.Pronunciation Fixes
If your agent mispronounces names, brands, or industry terms:- Phonetic spelling in prompts: write “Thought-lee” instead of “Thoughtly”
- Genius pronunciation guide: add entries to your Genius knowledge base with the correct spoken form
- Voice cloning: clone a voice that naturally handles your domain vocabulary
