The purpose of this study is to explore quantitatively the hypothesis that "resonant voice," may enhance recovery from acute laryngeal phonotrauma, based on molecular assays from human laryngeal secretions and secondarily, clinical tests.
The objective is to use the following operationalized question: Does a voicing mode shown to correspond to high-amplitude, low impact vocal cord oscillations, "resonant voice," improve the amount and time-course of recovery from acute phonotrauma, compared to vocal rest or spontaneous speech, as measured with molecular assays (primarily) and with behavioral and clinical tests (secondarily)?

Despite emergent progress in many fields of bionics, a functional Bionic Voice prosthesis for laryngectomy patients (larynx amputees) has not yet been achieved, leading to a lifetime of vocal disabili...
This study was inspired by the case of a robbery victim who was startled and reminded of the crime upon hearing a stranger's voice, while not clearly recognizing the speaker. To investigate whether sp...
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.
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.
A variety of techniques used to help individuals utilize their voice for various purposes and with minimal use of muscle energy.
Measurement of parameters of the speech product such as vocal tone, loudness, pitch, voice quality, articulation, resonance, phonation, phonetic structure and prosody.
Methods of enabling a patient without a larynx or with a non-functional larynx to produce voice or speech. The methods may be pneumatic or electronic.
