Voice all of a sudden disappeared for our VAPI assistants

Hi there! Sorry to hear you're experiencing issues with your VAPI assistants' voice. I don't have specific details about your particular setup, but I can definitely help troubleshoot this sudden voice disappearance issue. Here are some common causes and troubleshooting steps that might help resolve your issue: ## Common Causes of Voice Issues According to the information I found, there are several potential reasons why voice might suddenly disappear: 1. **Network Issues**: Unstable network connections can cause voice distortion or prevent the assistant from functioning correctly [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1332133296347549797). 2. **Configuration Errors**: Incorrect settings in your VAPI agent configuration could be causing the issue [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334024569861963788). 3. **Voice Model Issues**: Problems with the voice synthesis itself or limitations with specific voice models [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336377512233664523). 4. **API and Credential Problems**: Incorrect API keys or expired access permissions [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334024569861963788). ## Troubleshooting Steps Here are some steps you can take to diagnose and fix the issue: 1. **Check Network Connection**: Ensure you have a stable internet connection [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334024569861963788). 2. **Verify VAPI Agent Configuration**: - Check that your assistant ID is correctly set on your phone number [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336652401733668864).
- Verify that the voice ID is copied correctly from the voice library [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334563312762880085). 3. **Check API Keys and Permissions**: Double-check that your API keys are valid and have not expired [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334024569861963788). 4. **Review Voice Settings**: - Ensure the correct voice provider is selected (PlayHT, 11labs, etc.) [(source)](https://docs.vapi.ai/quickstart/web). - Check that the language setting for the voice model is correct [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1270786139355090995). 5. **Test on Different Devices**: Try testing the assistant on a different device to see if the issue persists [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334024569861963788). 6. **Check for Error Messages**: Look for any error messages in your VAPI logs that might indicate the source of the problem [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334024569861963788). Would you be able to share any additional details about your setup or any recent changes you made before the voice disappeared? This could help narrow down the issue further.

Hey, can you share more context about which voice disappeared for you and the Voice ID so I could take a look?
b
I’ve tried a few voices, but no voices I choose appear to work on our assistants anymore - since Thursday or Friday.
Here is the one assistant ID 09d22eaf-8be8-46cf-bfac-b1afaf895c9d
Currently it uses Athena from deepgram
The voice intermittently returns sometimes when I switch models. For example, I just switched to Claude, and the voice was back for one session. But now it’s gone again.
Btw I’m using the react native sdk for the client.
The issue is on iOS devices only

Do you have any Loom video or a Call ID where I can verify that you're using Voice X, but instead it uses Voice Y? Without a Loom video or a Call ID, we cannot verify your claims. It's highly required to help you further and be transparent in the investigation of your issue.

I understand - let me get that call ID for you
Here is one: c534c36e-0460-498e-8714-d9280d5f40b8
So the voice is in the recording, but it does not play on the device. I checked and even the "speech-start" event is not called.
Just some feedback on this: we solved the issue; it was related to another package - react-native-video - that interfered with the voice from the VAPI SDK. It seemed to have only been an issue on physical iOS devices.
It was changes in v6.11.0 that broke it, so to fix it we reverted back to v6.10.2
I have a hunch it's in the new "ios/Video/AudioSessionManager.swift"
