After nearly fifty years of hard exploration and research, speech recognition technology research received a great deal of development, some of which are relatively mature technology has been gradually applied to daily life. But on the whole, speech recognition in research and practical aspects of the difficulty is still relatively large. This article presents an overview of speech recognition technology, the whole picture, including its development history, the key technology used in specific applications, as well as the current difficulties facing the trends and research.
