Troubleshooting

Bluetooth Connection

Q1: Why does the homepage layout change but music and voice still play through speakers?

A: System Bluetooth is not connected. Check "Phone Settings" - "Bluetooth", confirm the corresponding Bluetooth (with i on the right) is connected. 🔗

Q2: Why doesn't the APP homepage layout change even though system Bluetooth is connected?

A: Might be connected to someone else's APP. Ask people nearby to turn off auto-connect in their APP, then return earphones to case and reconnect. 🔄

Q3: Why can't I find any information in connection management?

A: Please confirm your Bluetooth permissions are enabled. Open "Phone Settings" - scroll to find "VocalLink", enable Bluetooth and network permissions. 📱

Recording, Transcription, & Translation Issues

Q1: Why can I still transcribe English when I selected Chinese?

A: English is a universal language and can be recognized in any language setting. 🌐

Q2: Message "Recording interrupted due to interference"

A: Recording was interrupted by calls, music, alarms, or other system sounds. 📵

Q3: Message "No usable content recorded"

A: (1) Exited without speaking after recording started; (2) Recording volume too low for detection. 🔇

Q4: Voice broadcast plays through speakers even with earphones on

A: 1. Check if system Bluetooth is connected: "Phone System" - "Bluetooth", check if corresponding Bluetooth (with i on right) is connected. 2. On Android, frequent switching between earphone and phone playback can cause thread lag. This is common in many APPs and will resolve itself shortly. 🎧

Q5: Speaker differentiation not available

A: Could be due to recording duration. Speaker differentiation requires a certain length of voice material. 🕒
