The preferences panel lets you change the following:
Music on startup Talkhouse will play a random list of songs automatically when it starts.
Share Utterances This allows you to have your utterances anonymously mixed into future acoustic models boosting accuracy. Rather than only improving the models locally, all future versions will work better for you automatically.
Drag preference order Did you know you can drag copies of songs from the artist, album, and playlist tree panes? The drag preference order handles the case where you have two copies of the same song but in different formats. Talkhouse always plays the highest quality version available, but you may want it to drag a version that is smaller, or that is compatible with your portable music player instead. To change the drag preference order select a file type on the left and use the move up/down buttons to change its precedence.
