A preliminary examination technique for audio evidence to distinguish speech from non-speech using objective speech quality measures
Objective speech quality measures are utilized for detection of speech content. Speech quality measures show systematic differences on non-speech audio content. The method is tested on the largest and most diverse dataset used in such a study. Identification accuracy is higher when compared to previous studies. Method is robust against coding at low bit-rates and application of audio effects.
