I can't seem to toggle the options under "start speaking plan"

Hi there! Based on what I found in the documentation, the "start speaking plan" options can only be configured via the API, not through the Vapi dashboard interface. This explains why you're unable to toggle these options directly in the advanced section 🔧 To configure the "start speaking plan" settings, you'll need to make an API request with a JSON structure like this:

json
"startSpeakingPlan": {
  "waitSeconds": 0.4,
  "smartEndpointingEnabled": false,
  "customEndpointingRules": [
    {
      "type": "both",
      "assistantRegex": "customEndpointingRules",
      "customerRegex": "customEndpointingRules",
      "timeoutSeconds": 1.1
    }
  ],
  "transcriptionEndpointingPlan": {
    "onPunctuationSeconds": 0.1,
    "onNoPunctuationSeconds": 1.5,
    "onNumberSeconds": 0.5
  }
}

If you're working with languages other than English, note that

smartEndpointingEnabled

only works for English transcriptions and should be set to

false

for other languages like Italian. For better recognition of short words, you might want to try:

json
"startSpeakingPlan": {
  "waitSeconds": 0.8,
  "smartEndpointingEnabled": false
},
"transcriber": {
  "model": "nova-2-general",
  "language": "it",
  "provider": "deepgram",
  "endpointing": 300
}

Let me know if you need help with implementing these API configurations! 👨‍💻 Sources: - [Speech Configuration Documentation](https://docs.vapi.ai/customization/speech-configuration) - [Discord Discussion on Start Speaking Plan](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1329414710583627796)
