I'm having a problem with my agent. It's entirely in Brazilian Portuguese, using a native voice from 11labs. When I call it, the voice is completely buggy, with a strange accent, and unreadable. However, when I use VAPI's "Talk to Assistant," the voice is perfect, with no accent or speech errors. Can anyone help me? Do I need to make any specific settings?

Suggestion: Check the Call Logs in your [Vapi dashboard](https://dashboard.vapi.ai/) to compare the audio quality between "Talk to Assistant" and actual phone calls. This will help you identify if the issue is related to network, provider, or configuration differences. Go to

Observe > Call Logs

, select a problematic call, and listen to the audio playback for clues on what might be causing the buggy voice. If the issue persists, note any error messages or anomalies and share them for more targeted help. This is the first recommended step in the Vapi debugging guide for voice quality issues.

Hi Brennowisk, It sounds like you're experiencing differences in voice quality between test mode and live calls. Here are a few steps you can take to troubleshoot this issue: 1. Check Voice Provider Configuration: Ensure that your voice provider settings are consistent across both test and live environments. Sometimes, live settings might default to a different configuration. 2. Compare Call Logs: Use the [Vapi dashboard](https://dashboard.vapi.ai/) to access

Observe > Call Logs

. Listen to recordings of problematic calls to identify any discrepancies between test and live calls. 3. Network or Provider Issues: Differences might arise due to network conditions or provider-specific issues. Switching to a different provider, such as Azure or OpenAI, has resolved similar issues for others. 4. Configuration Review: Review your assistant’s configuration settings, especially any language-specific settings, to ensure they correctly match your intended setup for Brazilian Portuguese. Refer to the [debugging guide](https://docs.vapi.ai/debugging) for additional guidance. Following these steps should help you pinpoint the root cause of the problem.
