Speech Recognition Technology Summarize Voice recognition technology, also known as automatic speech recognition Automatic Speech Recognition, (ASR), whose goal is the human voice in the content words into a computer readable input, such as keys, binary code or sequence of characters. And speaker recognition and speaker verification is different from the latter try to identify or confirm the issue and not one voice of the speaker's words contain the content. Speech recognition technology, including voice dialing, voice navigation, control room equipment, voice document retrieval, data entry and other simple dictation. Voice recognition technology and other natural language processing techniques such as machine translation and speech synthesis technology combine to build a more complex applications, such as voice to voice translation. Speech recognition technology in the fields of: signal processing, pattern recognition, probability theory and information theory, vocal mechanism and hearing mechanism, artificial intelligence and so on. History Before the invention of early computer, the idea of automatic speech recognition has already been put on the agenda, early vocoder can be regarded as speech recognition and synthesis of the prototype. The 1920 production of "Radio Rex" toy dog may be the first speech recognition, and when the dog's name is calling when it can pop up from the base. The earliest computer-based speech recognition system is composed of AT & T Bell Labs developed Audrey speech recognition system, which can identify the number of 10 in English. The speech recognition method is to track the resonance peak. The system has been a 98% accuracy. To the late 1950s, the London College (Colledge of...
