The brain is responsible for controlling and coordinating the speech production process, but it is not a physical component of the vocal tract.

A phoneme is the smallest unit of sound that can distinguish one word from another in a language.

Neutralization is a process in which two or more phonemes merge into a single phoneme in certain contexts.

Speech recognition is the process of converting speech sounds into a digital representation that can be understood by a computer.

Rule-based systems are not commonly used in modern speech recognition systems due to their limited accuracy and flexibility.

Speech synthesis is the process of generating speech from a text or symbolic representation.

Waveform synthesis is not commonly used in modern speech synthesis systems due to its high computational cost and limited flexibility.

Phonetics is the study of the relationship between speech sounds and their acoustic properties.

There is no such thing as a Chinese Phonetic Alphabet.

Phonology is the study of the sound system of a language.

Elision is not a phonological rule, but rather a phonetic process that occurs during speech production.

Assimilation is the process of changing the pronunciation of a word to make it easier to pronounce.

Repetition is not a common type of speech recognition error.

Speech recognition evaluation is the process of evaluating the performance of a speech recognition system.

F-score is not a common metric for evaluating the performance of a speech recognition system.
