You can turn on the profanity filter for TalkType within the preferences area so that any form of profanity displayed in asterisks when dictating is.
First, open TalkType (either in the browser or the desktop application). In the top left-hand corner, you will see the TalkType logo with an arrow pointing down. Click on this, and then choose Preferences.
Scroll down on the page. You can check the box to turn on the profanity filter or uncheck it to disable it.
Once you have configured this, you can press the X close button at the top right-hand corner of the preferences screen to save your changes.
