The Research of Speech Recognition Based on Deep Learning
Abstract
In now the era of Internet screen, voice recognition function can be as complete and the computer exchange of hot technology, to be the bottom. In today's society, deep learning can find important information in a large number of databases, and learning deep is a hot spot in pattern recognition field. To it as a theoretical basis, has great practical significance to speech recognition, deep learning is mainly the nonlinear transform of the various levels of information extraction skills, through the level of, the realization of the modeling of the program. This paper mainly introduces the basic knowledge of speech recognition and learning deep, and focuses on how to apply learning deep to speech recognition research.
In view of development of computers and bid, data, the technology of deep learning, on the basis of voice and image processing, come into being,. Traditional technology of speech sounds demands high quality of personal skills, and it is a cc u r a c v is lower, applying deep learning to the recognition of speech sounds,imitating, the speech learning, and recognition of the brain.Utilizing, deep learning, to filter and train the features, during, the process of voice analysis, will rise the accuracy of the recognition of speech massively.
