Research On Locomotive Speech Recording And Querying System And Its Application

With the further development of the information technology, the real time detecting and recording equipment has become a popular field for the application of computer and its relative techniques. Therefore, in this degree paper, designing and applying an equipment to detect and record the locomotive operator's speech information is mainly concerned.The paper is made on the basis of two projects the author involved, namely, MVR01A multi-channel digital speech recording system and Meishan locomotive speech recording and querying system.The paper focuses on the following two aspects: The design and application of locomotive speech recording systemResearches, feelings, and views of the author about the project, mainly including: Researches on speech coding; Views on the relative software engineering concept occurring in the 'developing process of the project, such as how to guarantee thecontrollability of the developing process, the reliability of the lifestyle and issues concerning the reproduce of the project of same type.The paper traces a train of thought as follows:Creating a system based on the requirement of the design, summarizing and analyzing the main necessary techniques and ideas to apply it, and the author's own understanding during the practice.The paper takes steps forward in an order of raising, analyzing, solving and summarizing the problem.
