1. Download the audio file in format.mp3.wav (up to 5 seconds, bitrate not higher than 128 kb/s).

If your column does not support changing voice, you can go for a trick:

• 🔊 Connect the speaker to the smartphone via Bluetooth and play voice notifications from the phone.
• 🎭 Use third-party skills (such as Custom Voice in Mi Home, if available in your area).
