as your model for a realistic experience. Note that when using this model, only OpenAI voices can be selected as the voice used within the speech-to-speech model. [According to the documentation](https://docs.vapi.ai/openai-realtime).
## Voice Quality Settings
You can adjust these parameters to enhance realism:
- `stability`: Try setting to 0.5 to address fluctuation in tonality
- `similarityBoost`: A value of 0.75 is suggested
- `style`: Setting this to 0.0 is generally advisable for stability (higher values may cause unpredictability)
## Chunking Plan Settings
The chunkPlan.enabled
setting controls how text is processed:
json
{
"voice": {
"chunkPlan": {
"enabled": true,
"minCharacters": 30, // Adjust between 1-80
"punctuationBoundaries": [".", "!", "?", ";"] // Customize based on your needs
}
}
}
## Adding Voice Realism in Prompts
To make voices sound more natural, you can incorporate:
- **Stuttering**: "I-I-I don't know"
- **Hesitations**: "I was, uh, thinking about it"
- **Pauses**: "I… I don't know how to say this"
- **Emotional emphasis**: Using capital letters or exclamation marks
Is there anything specific about these settings you'd like me to explain in more detail?
