Audio Quality

Optimize audio quality for better conversations.

Common Audio Issues

Robotic/Choppy TTS

Causes:

• Network latency
• TTS provider issues
• Audio buffer problems

Solutions:

1. Switch TTS provider (try Azure or Sarvam)
2. Use native audio models (Gemini Live)
3. Check network stability

Echo

Causes:

• Acoustic feedback
• Speaker/mic too close
• Poor echo cancellation

Solutions:

1. Use native audio models
2. Enable enhanced echo cancellation
3. Reduce speaker volume

Background Noise

Causes:

• Noisy environment
• Low-quality microphone
• STT sensitivity

Solutions:

Enable noise filtering in agent config:

{
  "llmConfig": {
    "noiseFiltering": {
      "enabled": true,
      "sileroVad": {
        "confidence": 0.8,
        "minVolume": 0.7
      }
    }
  }
}

Words Getting Cut Off

Causes:

• Aggressive VAD
• Early end-of-turn detection

Solutions:

Use conservative VAD profile:

{
  "llmConfig": {
    "gemini-live": {
      "vadProfile": "conservative"
    }
  }
}

Provider-Specific Tuning

ElevenLabs TTS

{
  "ttsConfig": {
    "elevenlabs": {
      "stability": 0.7,
      "similarity_boost": 0.8
    }
  }
}

Higher stability = more consistent but less expressive

Sarvam TTS

{
  "ttsConfig": {
    "sarvam": {
      "speed": 1.0,
      "pitch": 1.0
    }
  }
}

Testing Audio

1. Go to Test Center
2. Select your agent
3. Make a test call
4. Listen for:
   • Clear speech
   • Natural pacing
   • No artifacts
