What Is Speech Perception?

The process by which people acquire information through the perception of speech in communication. Mainly refers to the phonological perception of oral speech. It can be divided into three stages (or levels): the auditory stage, where the auditory organs receive acoustic signals and perform preliminary analysis on them; the voice stage, which combines some acoustic features to identify the voice and determine the order of individual sounds; phonemes At the stage, each sound is converted into a phoneme, and the sound rules are applied to continuous sounds, so that these sounds are meaningful sounds of a certain language. Speech perception is not only restricted by the physical characteristics of speech, but also by the context (including the context of speech) when talking. ^[1]

Speech perception includes verbal perception and written language perception. It is a category perception. For the perception of written language, Zhou Xiangeng made research in the 1920s, and many psychologists have done a lot of research on the influence of the structure, glyphs, fonts, strokes, and changes of Chinese characters on speech perception in the future. The results show that Perception of speech has both material-driven and concept-driven effects. The perception of speech is based on the perception of words and sentences, which is "material-driven"; on the other hand, the understanding of sentences is restricted by my old experience, which is "conceptual-driven".

The impact of these two aspects is also manifested in the verbal perception of spoken speech, which can be divided into three stages: the auditory stage, the language stage, and the phoneme stage. The listener first performs a preliminary auditory analysis of each sound, analyzes the input speech signal into various acoustic features, and then the listener combines these features to identify the language and determine the order of the individual sounds, and then converts the individual sounds into phonemes , And use phoneme rules for language continuity, recognizing that these sounds are meaningful sounds of a certain language, which is basically "material-driven", but the particularity of daily speech activities is that words and sounds are not Will be presented in isolation, but in the continuous activity of speech, so the bottom-up processing from the perceptual level to the semantic level must be combined with the top-down semantic level implementation to the perceptual level processing. The process of making speech perception is not a process of passively receiving external information biologically, but an active cognitive process. Nowadays the research of psycholinguistics has shifted from the emphasis on linguistic structure to the emphasis on semantics. ^[2]
