How to turn on and off google map direction guide voice

Hey guys, we are regularly using Google Maps. We should know how to enable the direction guide voice.

1) Open the Map application. Search the location and start the ride.

2) Now you can see the "Sound Icon". If you want all direction guidance, choose the Speaker icon.  If you want alerts only. Choose the "Alerts only" icon. If you don't want to hear the sound, then choose the mute icon. 

In this way, we can manage map guidance sound.
