Hi! I understand that your voice recording analysis in the Vocal Image app keeps failing every time during your daily practice exercises. I’d like to help you get this working smoothly.

To start, could you tell me a bit more about the error? For example:
- Do you see any specific error messages when the analysis fails?
- Are you using the built-in microphone on your Mac, or an external mic?
- Have you noticed if this happens with all recordings or just some?
- Are your recordings free from background noise and interruptions?

Meanwhile, here are some general steps tailored for your Mac (OS X 10.15.7) to improve your recording quality and reduce errors in Vocal Image analysis:

1. Record in a quiet environment: Make sure no external sounds are picked up, as the app recommends only your voice should be captured during recording for best analysis10.

2. Check microphone permissions: Go to your Mac’s System Preferences > Security & Privacy > Privacy tab > Microphone, and ensure Vocal Image has permission to access the mic.

3. Use a compatible microphone: If using an external mic, verify it’s properly connected and recognized by your Mac. You can check this via System Preferences > Sound > Input.

4. Update the app: Ensure you’re running the latest version of Vocal Image, as updates often fix bugs affecting voice analysis.

5. Restart the app and Mac: Sometimes a simple restart resolves temporary glitches.

If you have tried any of these already, please let me know, so I can guide you towards more advanced troubleshooting or check for possible service-side issues.

Does any of this match your situation so far? Let me know, and we’ll take it from there!
