ABSTRACT:
A monosyllabic recognition apparatus is disclosed which includes a first memory which stores reference vowel patterns respectively representing vowel categories of known reference monosyllables of a preselected language, which are classified in accordance with the type of vowel characteristics of the language, the vowel categories independently including categories corresponding to a contracted sound and a syllabic nasal sound in addition to categories of basic vowels; a second memory which stores reference consonant patterns respectively representing consonant categories of the language, which are classified in accordance with the type of consonant characteristics of the language. A characteristic extracting section generates the acoustic parameter data of the input speech, which is divided by a segment processing section into monosyllabic acoustic parameter components. A speech recognition processing section compares each of the monosyllabic acoustic parameter components with the reference vowel and consonant patterns and performs monosyllable recognition in accordance with the determination of the vowel and consonant categories of the reference patterns which maximally resemble the monosyllabic acoustic parameter components.
