Vocal Cord Dysfunction Evaluation and Outcome of Conservative Treatment Abstract Objective: This article reports evaluation of 30 patients with Vocal Cord Dysfunction (VCD) and the outcome of conservative management program including voice therapy and breathing exercises. Study design: A prospective observational follow up study. Methods: Thirty consecutive referrals of refractory asthma patients and patients presented by laryngeal symptoms diagnosed as having VCD were assessed, treated and…

recognition. As discussed by Nilu Singh [1] that in early 1960 Lawrence Kersta of Bell Laboratories was the first person to develop a model for acoustic speech production which is based on “spectrographic voice verification”. Since the shape and size of vocal tract vary from one speaker to another it shows the differences in resonance frequencies [2] and [1] but now a days most of the speaker recognition system is based on the spectral information. The Swedish Professor named by Gunnar Fant…

melodies first appeared. Its characteristics, such as versatility, tone shading, and the importance of having an extensive vocal range are fundamental to the genre. The vocal arrangements and effects used to make the songs more emotive and powerful are quite varied. R&B songs are meant for the singer to open the doors of his or her soul to the people who are listening. Each of the vocal ad-ons explained, has a specific purpose and they all can cause an emotional reaction upon the audience and…

Stage I, cancerous cells have begun to develop. Cancerous cells can develop in the Supraglottis (both vocal folds function normally), Glottis, this is where cancer cells can develop on one of the vocal folds or both, and also the Subglottis. (cancer has spread to one of the vocal folds or both). Stage III the cancerous cells have spread supraglottis, glottis or subglottis. Cancerous cells found in the the supraglottis the cancer will be in other…

through the alveoli. Sentence: Even though each human body needs alveoli in their lungs in order to survive, there’s no set amount each adult has to have in order to keep their body moving. 2. Breathiness- A vocal quality characterized by the release of excessive breath because the vocal folds are not brought closely enough together during phonation; also caused by lack of breath support. Sentence: Breathiness in your voice is something to always keep in mind while speaking in front of a crowd,…

For example, energy is a measure of emotion, but it is the fluctuation/trajectory of energy, not the energy itself makes speech sound emotional. In order to understand speech production under anger we have investigated the vocal and acoustical changes caused by the anger mental state of the speaker. Extensive evaluations on several speech production features are made. The studies have shown that the presence of anger causes changes in phoneme production with respect to glottal…

the larynx and the laryngeal membranes, the vocal folds are abducted resulting in medial compression at the midline so air cannot escape. The thyoarytenoid makes up the majority of the vocal folds. The stylohyoid contraction at mandible will draw the hyoid up and down. With the tongue, positioning is helped by the hyoglossus in the phonotory system. Phonation is initiated as air pressure below the glottis overcomes medial compression, now the vocal folds are…

The systematic study of speech and the sounds of language is referred to as phonetics. Traditionally phoneticians rely on careful listening and observation in order to describe speech sounds (Nolan, 2007). Phonetics is often defined with respect to phonology. Both disciplines are concerned with the sound medium of language. Phonology is concerned with the pattering of sounds in a language (and in language in general), and is thus comparable to areas of linguistics such as syntax and morphology…

erratic, hoarse, or constricted. There are two primary types of spasmodic dysphonia: adductor spasmodic dysphonia and abductor spasmodic dysphonia. Those who have the adductor type will experience unexpected, involuntary muscle spasms that cause the vocal folds to smash together and become rigid. This movement results in the voice sounding stunted or smothered. Individuals who have abductor spasmodic dysphonia will experience similar involuntary muscle spasms, but these will cause the…

cavities (Honda 2003). These organs make up the vocal tract. According to Mahendru (2014), he stated that acoustic air waves are formed from the lungs that provide the air force to bring about sound. The sound starts its journey from the lungs that goes through a number of channels and makes its exit through the mouth and nasal cavities. According to Huffman (2016) the first modification takes place when air is made to flow in the larynx, here the vocal folds are positioned to produce sound.…
