Mechanisms of Speech Formation and Perception of Complex Sounds
Abstract According to classical concepts, the relationship between the first two formants is the feature that determines the identification of long vowels in speech. However, the characteristics of vowels may considerably vary depending on the conditions of their production. Thus, the aforementioned features that are valid for adult speech cannot be extended to speech signals with high fundamental frequencies, such as infant speech or singing. On the basis of the studies of preverbal infant vocalizations, singing, and speech imitation by talkingbirds, it is shown that the stable features of vowel-like sounds are the positions and amplitude ratios of the most pronounced spectral maxima (including those corresponding to the fundamental frequency). The results of the studies suggest that precisely these features determine the categorical identification of vowels. The role of the relationship between the frequency and amplitude characteristics in the vowel identification irrespective of the way the vowel is produced and the age and state of the speaker, as well as in the case of speech imitation by talkingbirds, is discussed.
