Abstract
A normal voice is judged according to whether the pitch, loudness, quality are adequate for communication and suit a particular person. A person may use a pitch which is too high or too deep, intensity that is too loud or too soft, or voice quality may be too hoarse, breathy or Harsh. Hoarseness of voice may be defined as a quality of voice, which is rough, grating, harsh more or less discordant and lower in pitch than normal voice: Hoarseness is purely a relative term. Setting the vocal cords in vibration by an air column is purely mechanical process. So anything that impairs the perfect working of this Mechanism produces voice disorder. Voice disorder is one of the important and major indicator of diseases of throat and nose. The present study titled "Analysis of voice disorders by Dr.Speech and Electroglottography", is mainly aimed at voice assessment inclusive of Hoarse voice, Harsh voice, Breathy voice, vocal fold regularity and Glottal closure time and etiopathology of voice disorder. Fifty cases randomly collected presented with change of voice of various etiology were at the Upgraded Institute Of Oto - Rhino Laryngology, Govt. General Hospital, Chennai, attached to Madras Medical College, during the period of study from October 2004 to September 2005 A.D. Dr.Speech is very useful to identify voice characteristics of different vocal cord pathologies and with in depth study of Dr.Speech and Electroglottography, it may be possible to approximate diagnosis just by analysing the voice assessment and EGG recordings. It is also useful in voice therapy to restore the voice in cases with non - malignant voice disorders, before and after medical and surgical management.
