Wave Runner offers a library of voices across multiple languages and accents. Click the play button next to the voice dropdown to preview any voice before selecting it.Language
Set the Language dropdown before choosing a voice. The language setting also controls the speech-to-text transcription model. Available languages: English, Spanish, Portuguese, French, German, Dutch, Italian, Hindi, Chinese, English & Spanish.If your callers speak both English and Spanish, select English & Spanish to handle code-switching.
Speaking speed
The Speed slider runs from 0.5× to 2.0×. Default is 1.0×. Slower speeds work well for complex instructions, legal disclosures, or callers who are non-native speakers. Faster speeds suit high-volume outbound calls with short, conversational exchanges.Response style
Response style controls how consistently the agent phrases its responses from call to call.| Style | Behavior | Best for |
|---|---|---|
| Focused | Stays on-script. Minimal variation. | Sales scripts, compliance, appointment booking |
| Balanced | Natural variation while staying on-topic. | Customer support, general inbound |
| Creative | More expressive, less predictable. | Brand personas that need personality |
Focused is the right choice for most agents. It produces the most consistent, testable behavior.
