Hi! I understand you’re trying to add your voice to the Suno app but keep running into a "7 failed" error after reading the supplied phrases. I’d like to help you get this resolved. To start, can you tell me a bit more about how you're recording your voice? For example:

- Are you using the app's built-in recording feature or uploading recordings separately?
- Did you notice any error messages or prompts other than the "7 failed" count?
- Is your Mac’s microphone being detected properly by the app?
- Have you tried adjusting microphone settings or using headphones with a mic?

Meanwhile, here are some steps you can try that often help with voice recording issues on Suno, especially on macOS 10.15:

1. Check Microphone Permissions:
Go to System Preferences > Security & Privacy > Privacy tab > Microphone, and ensure Suno app has permission to access your microphone.

2. Use a Clean Recording Environment:
Background noise or muffled audio can cause repeated failures. Try recording in a quiet room, speak clearly, and keep the mic at a consistent distance.

3. Follow the Phrase Instructions Exactly:
When prompted to read supplied phrases, make sure you enunciate clearly without rushing or pausing too long, as the app uses these phrases to build your voice profile.

4. Try the Latest Version of Suno:
Sometimes, bugs fixed in updates cause issues like failed recordings. Verify you have the newest version from their official site.

5. Restart the App and Mac:
A simple restart can refresh the permissions and services.

If you’ve already tried these steps or if the issue persists, it could be related to voice verification troubles some users experience, where the AI can’t match your recording properly. In such cases, redoing the voice registration process or contacting Suno support for a deeper investigation may be necessary.

I also found a helpful guide that walks through the full voice adding and verification steps on Suno, which might provide extra clarity: Suno Help: Use Your Voice in Suno 4.

Could you let me know what you’ve already tried and any specific details you’ve noticed? That way, I can guide you more accurately.
