Voice Disorders
The voice is a result of the interaction of the respiratory system, the larynx and the sound system. The air exhaled by the lungs passes through the vocal cords, which vibrate and this vibration of the vocal cords produces the voice.
The assessment of voice disorders is done with the collaboration of the speech therapist and the otolaryngologist. Otolaryngological examination includes video - stroboscopy and video - endoscopy, which are very important to identify the cause of the problem. The speech therapist through acoustic and perceptual analysis will collect objective data and proceed to the therapeutic intervention.
A voice disorder is present, when a person's voice quality, pitch, or loudness differ from or are inappropriate for their age, gender, cultural background, or geographic location, or when a person expresses concern about having an abnormal voice that does not meet daily needs, even if others do not perceive it as different or deviant.
The intervention is carried out to improve voice production and the coordination of respiration and laryngeal valving and is intended to:
- create appropriate vocal hygiene routines/practices
- capitalize on strengths and address weaknesses related to underlying structures and functions that affect voice production
- improve self-awareness of voice quality and kinesthetic factors (e.g., tension)
- facilitate the individual's activities and life participation by assisting the person in acquiring new communication skills and strategies
- modify contextual factors to reduce barriers and enhance facilitators of successful communication and participation and provide appropriate accommodations and other supports, as well as training in their use.
