Thank you for reporting the slurring issue with 11Labs. To help diagnose the problem, could you let me know if you have recently adjusted the voice speed, formatting settings, or if the slurring only happens after long responses or at specific points in the call?

To address the slurring issue with ElevenLabs voices, try fine-tuning the TTS parameters—especially speed and buffer settings—to improve clarity. For example, you can adjust the speech parameters in your integration:

{
  "voice": "elevenlabs",
  "parameters": {
    "speed": 1.0,
    "pitch": 1.0,
    "emphasis": 1.0
  }
}

{
  "voice": "elevenlabs",
  "parameters": {
    "speed": 1.0,
    "pitch": 1.0,
    "emphasis": 1.0
  }
}

Start by lowering the speed slightly (e.g., speed: 0.95) and test if the slurring improves. If the issue persists, review your buffer optimization and network latency settings as these can also impact real-time audio quality (source).

I don't think those properties actually exist

@Noah Johnson are you able to identify the elevenlabs setting you have assigned to the agent?
