Five-stage transformation of the speech signal

five-stage transformation of the speech signal in a message:

1. Peripheral auditory analysis,
2. Central auditory analysis,
3. Acoustic-phonetic analysis,
4. Phonological analysis and,
5. Higher order analysis (lexical, syntactic and semantic).

1. Peripheral auditory analysis refers to the process by which the ear receives and physically processes the incoming speech signal. This includes the mechanical and neural processes that occur in the ear, such as the conversion of sound waves into neural impulses.
2. Central auditory analysis refers to the process by which the brain interprets and organizes the neural impulses from the ear. This includes the processing of sound features such as pitch, loudness, and timbre.
3. Acoustic-phonetic analysis refers to the process by which the brain analyzes the specific features of the speech sounds themselves, such as the individual phonemes and their duration and intensity.
4. Phonological analysis refers to the process by which the brain recognizes and organizes the phonemes into larger units, such as syllables and words.
5. Higher order analysis refers to the process by which the brain interprets the meaning of the words and sentences and how they fit into the context of the overall message. This includes lexical, syntactic, and semantic analysis, in which the brain interprets the meaning of the words, the grammatical structure of the sentences and the context of the conversation.
