Speech to text

Dear sir
How can we set the voice volume when the speaker is too far from us when we use speech to text extension

You mean "turn up the microphone input" ?

Use the SoundManager : Helps to manage the sound of the device extension

to do something using a command using increase volume and call SoundManager2.RaiseVolume

and adapt

it to just ask for

it to call SoundManager2.RaiseVolume

should work.
