I have been facing a issue where the voice generation gets really slow during the call and the pitch also gets low. Please check the below call to check the issue. Call ID: a1afc279-9475-4342-8839-165b5653e761 time stamp: 00:25-00:36 Response issue: The voice generation was very slow and the pitch got very low. Expected Response: Clear voice generation and even pitch throughout the call.

If you're experiencing slow voice generation with low pitch, try adjusting the voice model settings. For 11labs voices, set the style property to 0.0 as higher values can cause instability:

json
{
  "voice": {
    "provider": "11labs",
    "voiceId": "your_voice_id",
    "style": 0.0,
    "stability": 0.5,
    "similarityBoost": 0.75
  }
}

This configuration helps maintain consistent voice quality throughout calls. Source: - [Discord conversation about voice distortion](https://discord.com/channels/1211482211119796234/1336377512233664523)

As @Vapi Support Bot told you, you can control the voice speed using voice configuration.

Based on the information I found, there's actually no direct way to control voice speed in 11labs, but you can improve voice consistency by adjusting these settings:

json
{
  "voice": {
    "provider": "11labs",
    "voiceId": "your_voice_id",
    "style": 0.0,
    "stability": 0.5,
    "similarityBoost": 0.75
  }
}

Setting

style

to 0.0 is crucial as higher values cause instability that affects pitch and perceived speed.

Adjust assistant settings for reduced response delay, select efficient voice models, use appropriate audio formats and sample rates, and implement real-time speech processing.
