What are the common features of language categories?

The similarities and differences of language categories are: the science of studying the essence, structure and development law of language.

The object of genre perception is vocal posture, and the process of perception is completed by decoding sound signals. The meta-analysis model holds that speech perception is an active meta-analysis process.

The transformation of language category from phonetic sound waves to phonetic symbols is completed through two processing stages. In the first stage, sound waves are converted into sound representations, and in the second stage, sound representations are converted into phonetic symbols.

Language category feature consciousness hypothesis holds that speech perception is the best proof through the theory of special feature consciousness. Experiments show that the fatigue of a certain phonetic feature will reduce the listener's response to the pronunciation with this feature.

Speech category awareness:

The perceptual process of a single speech can be divided into three stages: auditory stage, phonetic stage and phoneme stage. These three stages have different processing objects and characteristics. The main task of the auditory stage is to extract acoustic clues containing speech recognition information from the original speech.

The processing of speech stage is to recognize speech by combining acoustic cues extracted in auditory stage. The processing of phoneme stage is to convert the speech recognized in the previous stage into phonemes by using phoneme rules.

Phonetic category perception is particularly obvious in stops, fricatives and flowing sounds, but not in isolated vowels. If vowels are presented in context, they also show category characteristics. Language experience and dialogue practice will have certain influence on phonological category perception.
