Automatic speech translation based on the semantic structure

Describes a system for the semantic-based translation of spoken or written limited-domain utterances. The semantic structure, as the output of a semantic decoder, serves as the interlingua level. A word-chain generator combined with a linguistic post-processor produces the corresponding word chain in the target language. Both the semantic decoder and the word chain generator work with pure stochastic and trainable knowledge bases. The grammatical features of certain words can be easily extracted with the aid of both the word chain and the semantic structure
