Maintain A Deep Voice

Do you feel nervous and squeaky during online interviews and online business negotiations?
Sometimes our voice flips up and goes up even an octave. It's a falsetto. ..
If you want to keep your voice as deep as possible during the interview, please have this app next to your laptop and try it.
The function is simple, it analyzes the pitch of the voice picked up by the microphone in real time, and the screen glows yellow when a high voice is detected and red when a even higher voice is detected.
If the color of the screen changes to yellow or red, it means that your voice is awkward, so try to speak calmly and in a deep voice.
