Important prosody characteristics for spontaneous speech recognition

Abstract

For languages, especially for Czech language featured by a free-word-ordering, the prosody serves a critical information for the recognition and understanding system. For some sentences the speaker's style is essential to determine the core of the communication, depending on a speaker who thus emphasises a meaning of the sentence. This paper describes the first results of speaker's style determination. The experiments show that the speech recognition quality is increased by the style determination by using prosody characteristics.
