I have my

firstMessage

set to

Hi thanks for calling, this is Bob how can I help you today?

. Every time I call in either the "Hi" will get dropped or part of "calling" will get cut off.

It sounds like you're experiencing some frustrating issues with your

firstMessage

being cut off during calls. Here are a few troubleshooting steps you can try to resolve this: 1. **Check Silence and Speech Thresholds**: Make sure the parameters like

machineDetectionSilenceTimeout

,

machineDetectionSpeechThreshold

, and

machineDetectionSpeechEndThreshold

are configured correctly. Adjusting these can help prevent premature cut-offs. 2. **Review API Request**: Ensure that your API request for the

firstMessage

is correctly formatted and includes all necessary fields. For example:

json
   {
     "firstMessage": "Hi thanks for calling, this is Bob how can I help you today?",
     "firstMessageMode": "assistant-speaks-first"
   }

3. **Network Performance**: Check for any network latency issues that might be affecting the call quality. High latency can lead to cut-offs, so optimizing your network settings might help. 4. **Log Review**: Look at the logs for any error messages or unusual behavior related to the

firstMessage

. This can provide insights into what might be going wrong. 5. **Voice Volume and Pitch**: Ensure that the voice settings are not causing issues. Sometimes, high volume or pitch can lead to communication breakdowns. If these steps don't resolve the issue, it might be worth checking if there are any recent updates or changes in your system that could be affecting the

firstMessage

functionality. Let me know how it goes! 😊 Sources: - [Common Reasons for Voice Message Cut-Off](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336548894896816222) - [Troubleshooting

those solutions didn't help. Some more info: - I'm using 11labs for my voice provider - if i switch to openai as my voice provider the issue seems to be fixed but I want to use 11labs for my voice provider

@DanielN - maybe try these? 1. Adjust Stability Settings: The 'stability' parameter in ElevenLabs' Text-to-Speech (TTS) engine influences the consistency and fluidity of the generated speech. Lower stability settings can introduce variability, potentially causing parts of the speech to be dropped or altered. Increasing the stability value may result in more consistent outputs. You can adjust this setting in your Vapi configuration as follows:

{
  "voice": {
    "provider": "11labs",
    "voiceId": "your_voice_id",
    "voice_settings": {
      "stability": 0.75  // Adjust this value as needed
    }
  }
}

Experiment with different stability levels to find the optimal setting for your use case. 2. Incorporate Explicit Pauses: To ensure clarity and natural pacing, consider adding pauses in your initial message text using the syntax. For example: kotlin

Hi, <break time="0.5s" /> thanks for calling. <break time="0.5s" /> This is Bob. <break time="0.5s" /> How can I help you today?

This approach can help manage the speech flow and prevent unintended truncation. However, note that excessive use of SSML breaks may cause issues such as speeding up of speech or introduction of noise in the audio. It's recommended to use these pauses judiciously to maintain naturalness in the synthesized speech.

Thanks for these suggestions, unfortunately neither of them seem to resolve the problem. Also of note: api's recording of the call plays the firstMessage without any issues. 4d2bce70-dca2-43b2-b286-bb3dcf73ce13 is the assistant id. let me know if there's any more info i can provide to help debug

Hey @DanielN My apologies for the delayed response. l

To help track down this issue, could you share: - The call ID This would really help us figure out what went wrong!

here is the most recent call we experience the issue on: 3e145b46-6ff0-4bcc-9a87-769756c48aa8

@DanielN I just made the two calls by myself as well and your right
