How do I add pauses to a prompt when using OpenAI 4.0 as my llm model and 11labs as my voice model

@Chris To add pauses to a prompt when using OpenAI's GPT-4 for text generation and 11Labs for voice synthesis, you would typically use special symbols or tags to indicate a pause in the text that will be converted to speech. For OpenAI's GPT-4, you would simply include the pauses in the text as you want them to appear. For example, you might use ellipses (...) or commas for short pauses, and paragraph breaks for longer pauses. For 11Labs or similar voice synthesis models, you would use the Speech Synthesis Markup Language (SSML) or the platform's equivalent to control the speech output. In SSML, you can add a

<break>

tag to insert pauses of varying lengths. Here's an example of how you might write a prompt with pauses:

xml
<speak>
  Welcome to our service. <break time="500ms"/> Please wait while we process your request.
</speak>

In the above example,

500ms

indicates a half-second pause. You can adjust the time attribute to control the length of the pause. If you're ready to generate the text with pauses and then synthesize the speech, please provide the exact text you'd like to use, and I can assist you further with the process.

How do I tie these together in VAPI

@Chris To tie together the use of OpenAI's GPT-4 for text generation and 11Labs for voice synthesis within VAPI, you would typically follow these steps: 1. Generate the Text with OpenAI GPT-4: - Use the OpenAI API to generate the text you want to convert to speech. Include any necessary pauses in your prompt using punctuation or SSML tags if supported. 2. Convert Text to Speech with 11Labs: - Take the generated text and use the 11Labs API to convert the text to speech. If 11Labs supports SSML, you can include

<break>

tags in your text to indicate pauses. Otherwise, use the appropriate method provided by 11Labs to indicate pauses. 3. Integrate Both APIs in Your VAPI Application: - In your VAPI application, you would write code that first calls the OpenAI API to generate the text and then passes that text to the 11Labs API to perform the text-to-speech conversion. Here's a high-level pseudocode example of how this might look:

javascript
async function generateAndSynthesizeSpeech(promptText) {
  // Step 1: Generate the text with OpenAI GPT-4
  const generatedText = await openAI.generateText(promptText);

  // Step 2: Convert the generated text to speech with 11Labs
  const speechAudio = await elevenLabs.synthesizeSpeech(generatedText);

  // Step 3: Use the speech audio as needed in your application
  return speechAudio;
}

In this pseudocode: -

openAI.generateText

is a hypothetical function that sends a prompt to OpenAI's GPT-4 and returns the generated text. -

elevenLabs.synthesizeSpeech

is a hypothetical function that takes text and returns an audio file or stream synthesized by 11Labs. Please note that you'll need to handle API keys, request formatting, error handling, and other specifics according to the documentation provided by OpenAI and 11Labs. If you need assistance with specific code or API calls, please provide more details or ask for further support.

yeah this isn't how vapi works

@Chris I apologize for any confusion. To use VAPI for integrating OpenAI's GPT-4 for text generation and 11Labs for voice synthesis, you would typically follow these steps: 1. Generate Text with OpenAI GPT-4: - Use OpenAI's API to generate the text, including any pauses using punctuation or SSML tags if supported by the text-to-speech (TTS) service you are using. 2. Synthesize Voice with 11Labs: - Take the generated text and use 11Labs' TTS API to convert the text to speech. If 11Labs supports SSML, you can include

<break>

tags in your text to indicate pauses. 3. Integrate with VAPI: - In VAPI, you would use the appropriate endpoints to handle the text and voice synthesis. VAPI may have specific methods or endpoints for integrating with third-party services like OpenAI and 11Labs. If VAPI has a specific way of handling these integrations, you would need to follow the platform's documentation or reach out to their support for detailed guidance on how to properly implement these services together. Since I don't have the exact details of how VAPI integrates with these services, I recommend checking VAPI's documentation for "Get Call" and other relevant API references or contacting their support team for more information on how to proceed. If you have any specific questions about VAPI's capabilities or need further assistance, please let me know, and I'll do my best to help.

@Chris Please take a moment to review this article: https://help.elevenlabs.io/hc/en-us/articles/13416374683665-How-can-I-add-pauses, which provides guidance on how to incorporate pauses using 11labs. Additionally, ensure that ssmlParsing is enabled when utilizing the API.

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

This doesn't seem to work anymore?
