What technology does speech recognition embody?

Speech recognition technology, also known as AutomaticSpeechRecognition (ASR), aims to transform the lexical content in human speech into computer-readable input, such as keys, binary codes or character sequences. Unlike speaker identification and speaker confirmation, the latter tries to identify or confirm who the speaker is, not the lexical content contained in it. Speech recognition technology belongs to an important branch of artificial intelligence, involving many disciplines, such as signal processing, computer science, linguistics, acoustics, physiology, psychology and so on. , is a key link in man-machine natural interaction technology. Speech recognition is technically more complicated than speech synthesis, but it is more widely used. The biggest advantage of speech recognition ASR is that the user interface is more natural and easy to use. The fields involved in speech recognition technology include: signal processing, pattern recognition, probability theory and information theory, vocal mechanism and auditory mechanism, artificial intelligence and so on.
