Audio Settings

The audio settings affect how your assistant speaks and how creative its responses are.

Speech rate

Controls how fast the assistant speaks.

ValueDescription
0.8Slow — for older audiences or complex content
1.0Normal (default) — natural speaking pace
1.2Fast — for dynamic, short interactions
1.5Very fast — only for special use cases
💡

For medical practices and law firms we recommend 0.9-1.0 (calm and clear). For customer service, 1.0-1.1 can work well.

Temperature

Temperature controls how "creative" or variable the assistant's responses are. The value lies between 0 and 1.

ValueDescriptionRecommended for
0.0-0.3Very consistent, little variationFactual information, support, pricing
0.4-0.6Balanced (default: 0.5)General conversations, reception
0.7-1.0Creative, more variationConsulting, sales, casual conversations

When to use a low temperature?

  • The assistant relays fixed information (hours, prices)
  • Consistency is important (legal, medical contexts)
  • The assistant follows a strict script

When to use a higher temperature?

  • The assistant should sound natural and varied
  • Sales or consulting conversations
  • Creative, empathetic responses are desired
⚠️

A temperature of 1.0 can lead to unpredictable responses. For business applications, we recommend a maximum of 0.7.
