An Overview of Speech Recognition Technology

With the speech recognition research intensifying gradually in recent years, it is particularly important to grasp the research direction of this filed. This paper summarizes the theoretical algorithms in the development of speech recognition. Firstly, we introduce the specific process of speech recognition, including biometrics acquisition, preprocessing, feature extraction, biometrics pattern matching and recognition results. Besides, we emphatically introduce feature extraction and matching recognition algorithm. We also introduce the application platform, and give the specific application scenarios. Finally, we put forward the shortcomings of the research and prospect the future development trend.
