Voice & Personality Settings
Voice & Personality
The Voice & personality card in the Phone tab controls how your assistant sounds and behaves on a call.
| Setting | What it does | Notes |
|---|---|---|
| Language | The main spoken language, or Detect automatically to switch per caller. | Covers common business languages (English, German, Spanish, French, Italian, Dutch, and more). |
| Allowed languages | When auto-detect is on, the languages the assistant may switch into. | Shown only in auto mode. |
| Fallback language | The language to answer in when a caller speaks one you haven't allowed. | Shown only in auto mode. |
| Voice | The speaking voice. Leave on Automatic to let the platform pick a fitting voice, or choose a specific one and preview it with the speaker button. | Available voices depend on the language. |
| Greeting | The first sentence callers hear. Use {{company_name}} to insert your company name. | Up to 500 characters. The AI disclosure is spoken right after it. |
| Phone persona | A free-text description of the assistant's character and tone on the phone. Use Generate with AI to draft one. | Up to 3,000 characters. Safety and call rules always take precedence over the persona. |
| Speech recognition keywords | Product names and industry terms the speech recognition should prioritize, so it transcribes them correctly. | Up to 50 terms, this bot only. |
The underlying voice engine is chosen automatically by the platform for the best quality and latency; there's no model or speaking-speed setting to manage. You focus on the voice, greeting, and personality.
Example greeting
Hi, you've reached
{{company_name}}. I'm the AI assistant — how can I help you today?
The AI disclosure sentence is spoken automatically right after this, so you don't have to write "I'm an AI" into the greeting yourself.
Tip: After changing the greeting or voice, run a browser test call from the Test section of the Phone tab to hear it before going live.
