I have created an assistant but whenever I call it the voice will change sometimes to another voice. The new voice sounds like its in the background as well. Is this a token usage thing?

Based on the information found, voice changes in the middle of a Vapi assistant call are not caused by token usage. This issue has been reported by multiple users and is sometimes related to configuration mismatches (such as language or model settings). I recommend double-checking your assistant's configuration to ensure the correct voice and settings are selected. If the problem persists, consider reaching out to Vapi support for further assistance, as the exact technical cause is not fully detailed in the available documentation.

Can anybody tell me which models have configuration mismatches?

This may stem from inconsistent voice model settings, network issues, or voice provider configuration, so ensure consistent voice selection and stable connectivity to fix it..

It seems like trying to use the vapi voice lily is what is doing it. I changed the voice to one from eleven labs
