enableSsmlParsing: true

Hey Vapi team — could you enable enableSsmlParsing: true for my assistant? ID: e00b0804-2b77-48c9-b015-ad41d9d5be88
I’m using ElevenLabs (eleven_english_v1) and want to use <break time="1.5s" /> pauses in SSML. Let me know if anything else is needed. Thanks!

To enable SSML <break> pauses with ElevenLabs, set enableSsmlParsing: true in your assistant’s TTS config and include the breaks in your text.. https://docs.vapi.ai/customization/custom-voices/elevenlabs

I tried using the API to PATCH enableSsmlParsing: true, but I’m getting a 404 even with the correct assistant ID, API key, and endpoint. The assistant was created in the Vapi UI — can someone manually enable SSML parsing on the backend? @Kings_big💫 I am unable to find the TTS config.

Make sure to also specify which elevenLabs voice id you want to use with the ssmlParsingEnabled otherwise the PATCH will fail.

curl -X PATCH https://api.vapi.ai/assistant/id \
     -H "Authorization: Bearer " \
     -H "Content-Type: application/json" \
     -d '{
  "voice": {
    "provider": "11labs",
    "voiceId": "drew",
    "enableSsmlParsing": false
  }
}'

curl -X PATCH https://api.vapi.ai/assistant/id \
     -H "Authorization: Bearer " \
     -H "Content-Type: application/json" \
     -d '{
  "voice": {
    "provider": "11labs",
    "voiceId": "drew",
    "enableSsmlParsing": false
  }
}'

enableSsmlParsing: true
