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

The audio input level from your built-in or external microphone will have an impact on the quality of your transcriptions.

This video demonstrates how to set up and troubleshoot microphones for best dictation results with Talkatoo. See below for written instructions.

Microphone set-up


Higher means a more sensitive microphone.  For a noise-cancelling microphone set your volume around 70. For a built-in computer microphone set the volume to around 90.

These are initial settings, and every voice differs.  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 and adjust up or down as needed.
