Perceptual features of aging male speech
David E. Hartman, Jeffrey L. Danhauer · The Journal of the Acoustical Society of America · 1975
Spontaneous speech samples of 46 male speakers between the ages of 25 and 70 years were played to 40 untrained listeners who estimated the speakers' ages. Samples which showed agreement among untrained listeners were played to 20 trained listeners who described the perceptual features of the given perceived ages via an a posteriori schema. Results showed characteristic perceptual features for four perceived age decades which could be classified to pitch, rate of speech, quality, and articulation. It was concluded that the features identified should be useful for defining the criteria of “normal” aging speech, and in traditional speaker recognition research.
