Computerised objective measurement of strain in voiced speech.

Voice quality assessment is required by healthcare professionals in patients suffering from voice problems. Speech and language therapists (SLTs) use a well-known subjective assessment approach which is called GRBAS, to quantify voice problems. GRBAS is an acronym for a five dimensional scale of measurements of voice properties which were originally recommended by the Japanese Society of Logopeadics and Phoniatrics and the European Research for clinical and research use.
