Check microphone permissions if recording fails
Check whether the browser or app has permission to use the microphone. Make sure the device has a working microphone and another application is not using it. Try again after resolving the issue, or send the same question by text. Avoid repeated sends until you know whether the first message succeeded.
Try a short voice note
Record: “I want an idea for a small weekend project. Can you suggest one simple option?” Send it, read the reply and clarify one detail by text if needed.
