Sonneta adds speech measures
An update to Sonneta was released January 19, 2013 containing very relevant new features. The most important of these is the addition of dysphonia measures for continuous speech. In November, a review paper was published by ASHA's National Center for Evidence-Based Practice in Communication Disorders that discussed acoustic measurement studies that met the highest standard of evidence. Three acoustic measures from these studies were good candidates to incorporate into Sonneta. The Spectral Tilt, Spectral Flatness of the Residue (SFR) and Pitch Amplitude (PA) measures can all be used with continuous speech or with sustained phonations. In addition the Cepstral Peak Prominence (CPP) measure has become more popular recently and was also incorporated.
These and other features such as formant display are available in the latest version of Sonneta.
