VAPI Voice Assistant Voice Changes

Hello support! I'm running into an issue where the generated voice output is changed between interactions. I've been able to reproduce this issue a few times now. **Call ID**: e7a64767-deb6-4d40-83cb-c8de5bcd6355 **Timestamp**: 15:34:44:590 **Expected Response**: Consistent voice profile across the call **Received Response**: Voice profile shifted to that of a man's voice on a telephone call.

If you're using 11labs voices, try adjusting these voice settings to fix the profile shifting issue:
Copy code
json
{
  "voice": {
    "provider": "elevenlabs",
    "voiceId": "your-voice-id",
    "stability": 0.5,
    "similarityBoost": 0.75,
    "style": 0.0
  }
}
High style values (e.g., 0.8) can cause voice instability and unexpected changes. Setting it to 0.0 is generally recommended for consistent voice output.
