| Summary: | 碩士 === 國立臺北科技大學 === 電子電腦與通訊產業研發碩士專班 === 95 === This paper is pertinent to the principle based Adaptive Mulit-Rate (AMR) and its relevant theory. As the AMR speech coding specifications and simulation programs are complicated and not easy to understand, it takes a lot of time for the R&D (Research and Development) engineers to understand its structure.
With the development of AMR, use Unified Modeling Language (UML) for analysis and design to get a reference model of AMR. This model is provided to different people for use. Furthermore, it is also a pre-requisite for setting standards for AMR reference model. It satisfies the needs of AMR Technology Company which requires techniques in real time in order to save the developing time for communication and research department engineer. This is a pre-requisite, since in such a highly competitive telecommunication industry developing time needs to be very less, as the commercialization of R&D products has become a key point to obtain maximum profits.
Finally, the paper proposes an AMR reference model and develops a value added service via speech system without changing the content of the program and maintaining the communication specifications of the AMR receiver. The purpose is to allow the mobile users take benefit of this reference model and examine all the possibilities and practicalities of it.
