iOS Question Change the volume of the voice output "TTS".

[Deleted member 103]

Hi,

Is there a way to change this volume control by code?

I have expressed myself wrong, I do not want to change the control but only the volume.
In my app I use the voice output "TTS" and here the volume can not be adjusted.
