Objective: This study focuses on the relation between objective voice quality and the self-perception of a voice handicap. Patients and Methods: The study group consisted of 86 German-speaking patients (51 women, 35 men) suffering from benign dysphonia. The test persons completed the German version of the Voice-Related Quality of Life (V-RQOL) Questionnaire without prior information about their diagnosis and underwent voice analysis with the Dysphonia Severity Index (DSI) being the parameter of this study. Results: No correlation between V-RQOL and DSI could be found (p > 0.05). On the V-RQOL, women scored worse than men, but not at a significant level. Patients with dysphonia of organic origin scored significantly worse than patients with functional dysphonia (p = 0.026). On the DSI, men's values were significantly lower than women's (p = 0.001). Organic dysphonia caused significantly lower DSI values than functional dysphonia (p = 0.011). Conclusion: Objective voice quality and the individual perception of voice quality by the patient are independent parameters. Both need to be assessed in clinical practice.

Pathological processes that affect voice production, usually involving VOCAL CORDS and the LARYNGEAL MUCOSA. Voice disorders can be caused by organic (anatomical), or functional (emotional or psychological) factors leading to DYSPHONIA; APHONIA; and defects in VOICE QUALITY, loudness, and pitch.
Clinical manifestations that can be either objective when observed by a physician, or subjective when perceived by the patient.
That component of SPEECH which gives the primary distinction to a given speaker's VOICE when pitch and loudness are excluded. It involves both phonatory and resonatory characteristics. Some of the descriptions of voice quality are harshness, breathiness and nasality.
Measurement of parameters of the speech product such as vocal tone, loudness, pitch, voice quality, articulation, resonance, phonation, phonetic structure and prosody.
A rigorously mathematical analysis of energy relationships (heat, work, temperature, and equilibrium). It describes systems whose states are determined by thermal parameters, such as temperature, in addition to mechanical and electromagnetic parameters.
