If you suspect an audio input problem, the first thing to do is to run the Audio Setup Wizard. The Audio Setup Wizard can do either a complete setup or simply adjust the volume.

If NaturallySpeaking has been working okay to date and only now has begun making errors, your microphone may have moved a bit, or you may be speaking more or less loudly than before. In that case, you only need the wizard to adjust the volume. Choose the Audio→Read Text to Improve Accuracy Wizard from the DragonBar, and follow the instructions.

Running the Audio Setup Wizard at this point can be very helpful. Accessing it by going to the Audio Setup Wizard from Audio→ Check Microphone again will adjust the volume and check the quality of the audio. Whether you pass, the audio is acceptable, or if the quality check fails, you can click the Play button to listen to a playback of the audio that Dragon hears.

Some PCs have more than one sound system installed. For instance, you may have installed a better sound card than the one your PC came with, but the original is still present. If you’re using a USB microphone, you almost certainly have two sound systems. If you have more than one sound system, the first screen that the Audio Setup Wizard displays asks you to choose the sound system.

You must choose the system your microphone is connected to: USB Audio Device if you’re using a USB microphone, for instance. If the choices don’t mean anything to you, click Default and proceed. If you choose incorrectly, it will complain that the sound level is too low. Click Cancel to exit the Audio Setup Wizard, and then restart it and choose the other sound system.

You engineers and serious audio geeks out there can try pressing Alt+1 when the Results screen appears. All kinds of cool, technical displays appear as you talk.

If volume is low, consider speaking a bit louder or moving the microphone slightly closer to your mouth. If you’re tired, take a break! Your volume may vary considerably over the day and could be lower when you’re tired, sitting with poor posture, or sleepy.
