speak.* runtime options and deployment settings related to text-to-speech, voices, pronunciation, ambient audio, and speech delivery.
Speak settings are used by voice-capable deployments: Phone Call, Web Widget with spoken responses, and Web App / SDK with spoken responses. Text-only channels do not use speak configuration.
Configure it
Open your assistant, select Configure Assistant, then open Deployments. Speak settings appear in the Voice Output step for each deployment that supports spoken responses.| Area | What it controls |
|---|---|
| Text-to-Speech | Provider, credential, model, voice, language, and speech synthesis behavior. |
| Pronunciation | How dates, times, numbers, addresses, URLs, acronyms, and domain terms are spoken. |
| Delivery | Pause behavior, conjunction boundaries, and optional ambient audio. |

Troubleshooting map
| Symptom | First place to look |
|---|---|
| Assistant voice starts slowly | Text-to-Speech model latency and response length |
