Аннотация:This paper discusses the results of experimental researches in the field of auditory recognition of speech semantic content on the basis of Russian spoken discourses in noise. In the analysis some spoken discourses in noise were offered to listeners for auditory perception and then recognition of main topics and subtopics of the stimuli. In speech perception researches a listener is usually considered “a decoder” of sounds and syllables. The listeners were supposed to respond to questions about speech fragments or prosody of utterances. These experiments are relatively simple. More difficult is the task of speech signals recognition regarding intelligibility in noise, and most difficult are experiments on perceptual recognition and understanding of semantic content (topics and subtopics) of speech flow in noise. And our aim was to investigate the possibility of auditory recognition of the third type of researches.
