To change the speech recognition volume

To adjust the volume input levels, follow the procedure below. However, not all devices support this option in the same way. Some devices will not support volume control and the Volume button will be unavailable. Other engines may use their own display. In those cases, follow the instructions presented on the screen or documented separately with the engine.
  1. In Control Panel, double-click the Speech icon.
  2. On the Speech Recognition tab, click Audio Input, then click Volume.
  3. A volume control mixer will be displayed. Adjust the appropriate device to the required level.


  • To open a Control Panel item, click Start, point to Settings, click Control Panel, and then double-click the appropriate icon.
