How to adjust your microphone volume levels to prevent background noise and ensure quality dictation

The audio input level from your microphone will have a large impact on the quality of your dictation



This video demonstrates how to set up and troubleshoot microphone levels for the best dictation results with Talkatoo in Windows.

Higher means a more sensitive microphone.  For a noise-cancelling microphone set your volume around 60-70. For a built-in computer microphone set the volume to around 70.

These are initial settings, and the optimal setting will depend on your voice and your environment.  If you're using the Philips SpeechMike, or another really high quality noise cancelling microphone, and have a lot of background noise, especially people speaking, try setting the level at 40-50 and adjust up or down as needed.  

Even if there is not a lot of background noise, in some cases we find that 70 is too high and lowering it to 50 provides much more accurate results.
