Why is there a delay when using Bluetooth earbuds for voice input on the Xiaomi 11 Lite 5G NE?

If there is a delay when using Bluetooth earbuds for voice input on the Xiaomi 11 Lite 5G NE, please refer to the following details:
1. It takes time for the audio signal to travel from the earbuds to the phone and back. The latency can vary depending on the codec being used. The Xiaomi 11 Lite 5G NE supports SBC, AAC, LHDC and LDAC, please ensure these are enabled for faster transmission;
2. If your phone and earbuds use an older software version, this can result in a delay. Please keep both your Bluetooth earbuds and your phone’s software updated to the latest version;
3. When using voice input, the phone processes the voice data before it responds, which can add a delay. The more complex the voice recognition task, the longer the processing time will take. Background apps use your phone's CPU and memory resources, which can slow down the response time. You can try closing unnecessary background apps;
4. Bluetooth operates on the 2.4GHz frequency, which is shared by many other devices like Wi-Fi routers and other Bluetooth devices. Interference from these devices can cause a delay in the signal, leading to lag in the voice input response. Try to minimize other Bluetooth devices that will interfere with the signal, or use the earbuds in an area with less wireless congestion.
