Auditory Perception of Voice Signals with Abnormal Sounding in Children

Invariant and noise-proof speech understanding is an important human ability, ensured by several mechanisms of the audioverbal system, which develops parallel to mastering linguistic rules. It is a fundamental problem of speech studies to clarify the mechanisms of this understanding, especially their role in the speech development. The article deals with of the regularities of auditory word recognition in noise by preschool children (healthy and with speech development disorders) and patients with cochlear implants. The authors studied the recognition of words using pictures (by children) and verbal monitoring, when the subjects were stimulated by isolated words with one or all syllables in noise. The study showed that children's ability to perceive distorted words develops in ontogeny and is closely related to the development of mental processes and mastering linguistic rules. The data on patients with cochlear implants also confirmed the key role of the central factors in understanding distorted speech.
