Abstract
A method of speech recognition and language-understanding analysis is provided. According to a segmental word-concept-tag compound N-gram model, an input speech is divided into a plurality of segmental phrases. Each segmental phrase is attached a tag to indicate whether said segmental phrase is a meaningful segmental phrase or a meaningless segmental phrase. The meaningless segmental phrases are deleted, and only the meaningful segmental phrases are reserved. The language-understanding analysis is carried out to the meaningful segmental phrases according to segmental sub-grammars.
