PitchWorks is the main tool for any intonation studies, with very easy user interface. It uses two methods of pitch extraction, Cepstral and Autocorrelation.. PitchWorks is designed for up to 10 levels of tiers for TOBI style labeling, with virtually unlimited number of labels in each tier. Labels can be of different fonts, colors or sizes. The tier information can be extracted to a log file by click of mouse.  Each screen can be saved as a bitmap for direct entry into word document. Pitch Works reads many different file types of any size.
