To select an audio input device

To select an audio input device

1. In Control Panel, double-click the Speech icon.
2. On the Speech Recognition tab, click Audio Input.
3. Select either Use preferred audio input device or Use this audio input device.
   
   
   Use preferred audio input device sets the input device to the default for the system. Select this option if you want your speech applications to use the same input device as all other sound for the system. Often, computers will have only one input device, such as the headset microphone. This is the default in Speech Properties. The default device is designated by Sounds and Multimedia in Control Panel as Sound Recording on the Audio tab.
   
   
   Use this audio input device allows you to select another device for speech applications only. Select this option to change to another input device. The drop-down list box becomes active only if other devices are available. From this drop-down list, select the device you want. Making a selection here does not change the default device for other audio applications. For example, you may wish all speech input to use the headset microphone rather than a omnidirectional microphone.
