Voice Settings

Regal gives you a lot of ways to tune your AI Agent voice.

Description: Controls how fast the agent speaks.
Range: 0 to 2.0
Default: 1.0
Recommended:
- ~1.1 for most customer segments - slightly increasing speed often sounds more natural and helps maintain momentum on calls.
- However if your customer demographic is older e.g., 50+ it's better to leave the speed at 1.0

Description: Adjusts the variation in tone and emotion. Higher values sound more expressive, while lower values are more consistent.
Range: 0 to 2.0
Default: 1.0
Recommended:
- Most product use cases value predictability in the exact tone, inflection, pronunciation of verbatim statements or phrases, then target ~0.60 or 0.70
- However, if you want more open ended conversations, you can try ~1.15 - adds just enough variation to sound human without sacrificing clarity.

Description: Controls how loud the agent’s voice is.
Range: 0 to 2.0
Default: 1.0
Recommended: 1.0 - Most voices sound best at the default level. Only adjust if you notice the agent is unusually quiet or loud.

Description: Determines how quickly the agent starts speaking after hearing the contact.
Range: 0 to 1.0
Default: 1.0
Recommended:
- 1.0 for most use cases - provides a natural pause before speaking. Reducing this will add intentional latency to each response of the AI agent.
- For older demographics who are a bit slower to speak or make drag out responses or be chatty, start at 0.90 - 0.95 to avoid the AI agent speaking over the customer. You may need to dial it down even more.

Description: Controls how easily the agent detects and responds to interruptions from the contact.
Range: 0 to 1.0
Default: 0.7
Recommended:
- 0.7 - This setting strikes a balance between ignoring background noise and picking up genuine interruptions.
- Note: if your use case is for users in the field e.g., technicians and there is consistently background noise on the calls, you can test lowering this setting.
