Correct microphone positioning is one of the most important ways to enhance recognition accuracy. Even slight variations can deteriorate accuracy significantly.
Positioning a headset microphone
- Place the microphone element to the side of your mouth to avoid noise from breathing.
- Keep the microphone element about an inch from the side of your mouth, but not touching it.
- Make sure the front of the microphone points toward your mouth. The front may be labeled with, for example, a colored dot or the word "Talk."
- Position the headset consistently every time you use it.
Positioning a hand-held microphone
- Do not hold the microphone directly in front of your mouth. Hold it below or to the side of your mouth to avoid noise from breathing.
- Keep the microphone element about 1 to 3 inches away from your mouth.
- Point the front of the microphone toward your mouth. Don't talk into the side of it.
- Be careful not to move the microphone or your head suddenly.
- Do not use a microphone stand or holder. This will make it harder to maintain a consistent position, and the stand may conduct noise.
- Hold the microphone consistently every time you use it.
