I'm trying to add a pronunciation rule. I'm making a POST request with the following body to https://api.vapi.ai/provider/11labs/pronunciation-dictionary:

{
  "name": "Finance Dictionary",
  "rules": [
    {
      "stringToReplace": "INV-",
      "type": "alias",
      "alias": "I N V dash"
    }
  ]
}

But I'm getting a 400 error with a response body of:

{
  "message": "Unsupported data type. Either file or rules must be provided.",
  "error": "Bad Request",
  "statusCode": 400
}

Why?

Hi DeeGee, To change the pronunciation of specific words using Vapi, you can create a pronunciation dictionary with custom rules. Here's a concise guide on how to implement this: 1. **Create Pronunciation Rules**: Define these using phonetic notation (IPA, CMU Arpabet) or alias rules. 2. **Upload to Vapi**: Use Vapi's API to create your dictionary.

plaintext
   POST https://api.vapi.ai/provider/11labs/pronunciation-dictionary

3. **Configure Your Assistant**: Update your assistant’s voice configuration to include this dictionary.

json
   {
     "voice": {
       "model": "eleven_turbo_v2_5",
       "voiceId": "sarah",
       "provider": "11labs",
       "pronunciationDictionaryLocators": [
         {
           "pronunciationDictionaryId": "your-dictionary-id",
           "versionId": "your-version-id"
         }
       ]
     }
   }

4. **Test Pronunciation**: Verify the changes using a test call or the Vapi playground. Detailed steps and examples can be found in the [Pronunciation Dictionaries documentation](https://docs.vapi.ai/assistants/pronunciation-dictionaries). Feel free to reach out if you need more assistance.

I've followed steps 1 and 2, as shown in my original post, but I'm getting a 400 response. Why would that be?

Hey, can you send me a screen recording video that walks through the issue you are facing? It would be easier for me to understand your issue and help you out with it.

No problem, I've solved it ... user error.

For pronunciation dictionaries workaround, you can use
