Sigtuna DAR 3 and other DAISY production tools have a feature called "phrase detection". This feature detects the pauses in the narration and automatically creates individual audio phrases based on the pauses. Phrase detection is useful both in production and during playback for the reader of the completed book. The default is for phrase detection to be active. If you do not want to use phrase detection you must deselect it in the check box.
