In some cases, the recording quality may not be adequate for analysis by the software not recognizing what you said.

The recording quality may be poor due to:

• Using the built-in microphone in a laptop instead of a headset microphone
• The sound settings have two or more microphones activated
• Using a headset without noise reduction technology
• Faulty/noisy microphone or sound card on the computer
• Excessive background noise or chatter
• Recording volume set too low or too high
• Microphone placed too close to the mouth
•
