Speech Technique Research Of Intelligence Robot

Intelligence robot is on the direction support by national "863" program . Speech recognition and synthetic technology is one of the main embodiment of smart robot techniques , which made natural man-machine conversation, so that robots can follow men's command. Applied in information service, enterprise advertisement publicity ,machine guide etc. Speech recognition and synthesis technologies are two key technologies to achieve both voice communicating, and establishing of tongue system with ability to listen and speak . Be an important competition market of the information industry in the new century.This text looked back the development of the intelligence robot at first , combined with application of speech technique in the intelligence speech robot, discussed the development and existent problem of speech recognition and synthesis technology. Pointed out the development direction of the speech synthesis in the future and the meaning of the Chinese language speech synthesis, introduced foundation knowledge of the speech signal processing included mathematics model of the modern phonetics and the speech signal, and some characteristic of various speech synthesis technique and the Chinese language speech, discussed investigation of speech synthesis and with linear Predictive synthesize(LPC) realized carry out Chinese language speech synthesis.In this text, some researches to the process and method of the speech signal processing is carried on; making use of the physical model created by the speech signal, used the LPC technique to take this physical model into abstract, gained mathematics model of the speech signal .Making use of the LPC technique , built up a linear prognosticate model in the meantime, examine keynote period of sonant, realized a Chinese language speech synthesis on the base of LPC technology finally. In the end ,discussed application of speech synopsis and embedded TTS Chinese language speech synthesis using in the intelligence robot, and put forward own standpoint.With using the Microsoft TTS engine , drew up a TTS demo with Vc++6.0 language .At the ending of this text , made summary to the work being done, and discussed development direction of the intelligence robot speech technique aftertime.
