Study of the characteristic parameters of the normal voices of Argentinian speakers

The voice is a multidimensional phenomenon that must be evaluated using special tools for determining acoustic parameters. These parameters are: the pitch or voice tone, the timbre, considered as the personality of the voice that is particular of each person (determined by fundamental frequency, its harmonics and formants) and the degree of hoarseness. During sustained vibration, the vocal fold will exhibit variations of fundamental frequency and amplitude; these phenomena are called “frequency perturbation” (jitter) and “amplitude perturbation” (shimmer). They reflect fluctuations in tension and biochemical characteristics of the vocal
