A method for voice evaluation having three analysis steps is described. First, the subject is caused to stand with the arms at the sides and produce a yawn-sigh-like sound ('AH') without vibrato for approximately one second. The subject is instructed to begin the sound fairly high on the vocal scale, using the light mechanism of the voice, and to gradually lower (descend) the pitch of the tone in a smooth sliding/glissando effect. The tone descends through the middle voice and down through the chest voice or heavy mechanism of the voice, ending on the lowest tone that the subject can produce. The analyst listens to the quality of the descending tone evaluating it for clarity across the vocal scale and listening for disturbances in the quality, registration, resonance and placement of the tone, as well as a skip/interruption in the tone, a flutter/shakiness, a double tone, or any other vocal aberration. Second, the subject is caused to turn the head to a first side, facing the shoulder, without turning the torso, thus inhibiting the functioning of the vocal cord on the side being faced and allowing the vocal cord on the opposite side to vibrate freely so that it may be examined. The subject is then instructed to produce a yawn-sigh-like sound as described under the first procedure and the analyst listens to the tone produced and evaluates it as described in the first analysis step. Third, the subject is instructed to turn the head to the opposite side, facing the opposite shoulder, without turning the torso. The subject is then caused to produce the yawn-sigh-like sound as described under the first procedure and the analyst listens to the tone produced and evaluates it as described above. The analyst then compares the tone produced by the subject when facing forward with the tone produced when facing to the first side and then when facing to the opposite side. The tones produced are then analyzed to determine the type, severity and location of bumps or protrusions, swellings, or irritations.
