Microphone Audio Quality Examples

If using the voice client for dictation, audio quality makes all the difference between a good experience and a bad one.
Many factors can influence audio quality, including the microphone that you use, speaking too loud or too fast, or even background noise in the environment in which you're dictating.
Below are some examples of good and of bad audio quality to help you identify audio problems and what causes them.
Example: Good Audio Quality
Example: Correct Microphone
The audio on this example was recorded with an nVoq-approved microphone. The recording is clear and easy to understand.
The audio on this example was recorded with an microphone that was not approved for use with the voice client. The audio quality is poor, and there is a low signal to noise ratio.
Below is another example recorded with an microphone that was not approved for use with the voice client. Once again, the audio quality is poor with a scratchy noise included in every "S" sound.
How to Fix It: Exit the voice client completely and connect nVoq-approved audio equipment to your computer. (See our list of Recommended Microphones.) Then launch the voice client again and run the Microphone Setup Wizard.
In this example you can hear the sound of people in the background talking or laughing which can result in poor dictation accuracy.
How to Fix It: Use a noise-cancelling microphone, and make sure the microphone is in the correct position. If you still have problems, record in a quieter environment.
In this example you can hear the sound of mechanical equipment running in the background which can result in poor dictation accuracy. A similar problem could occur from music playing on a computer or television playing in the background.
How to Fix It: Use a noise-cancelling microphone, and make sure the microphone is in the correct position. If you still have problems, record in a quieter environment or turn down the sound (i.e. music or television playing in background).
Audio recordings with dropped packets (or packets out of order) are said to have "jitter". This can be caused by audio card or network issues.
How to Fix It: Verify that hardware (sound card or audio equipment) connections are secure and then try restarting your computer. Verify the Internet connection speed using the voice client bandwidth test.
If audio is too loud, it sounds distorted and is hard to understand. Recording information is missing or "clipped".
How to Fix It: Make sure the microphone is in the correct position, not too close to the mouth. If necessary, move the microphone farther away from the mouth and run the Microphone Setup Wizard again. See Also: Audio Clipping video.
Problem: Speaking Rate Too Fast
