Engine Tab
The Engine Tab handles advanced technical settings that govern how the agent processes speech and manages silence.ASR Settings (Speech-to-Text)
- Model: Select the ASR model (e.g., Deepgram Nova-2, Sarvam v2.5).
- Endpointing: Determines how long the agent waits for the user to stop talking before processing.
- Min Interrupt Threshold: How loudly/clearly must the user speak to interrupt the agent while it is talking?
Buffer Settings
Configure how sentences are streamed from the LLM to the TTS engine. Optimizing these values is key to reducing “Time to First Word.”Silence Timeout
How long should the agent wait for user input before saying a “re-engagement” phrase or hanging up?- Default: 10 seconds.
- Prompt hint: “If the user is silent, say: ‘Are you still there? I’m happy to help if you have more questions.’”
