Description
Technical field
The present invention relates to intelligent voice system, particularly a kind of Computer Distance Education system.
Background technology
Speech recognition includes the process for the word said is converted into text.Generally, speech recognition system is by oral
Sound is mapped to the readable voice of series of computation machine, and to those voices to and the relevant known speech pattern of word compare.
Such as, mike can accept following analogue signal, and described analogue signal is converted into the numeral being hereafter divided into more segment
Form.The element of digital section with said language can be compared.Compare according to this and to the environment sending those voices
Analyzing, system is capable of identify that voice.
Typical speech recognition system can include acoustic model, language model and dictionary.In short, acoustic model
Numeral including each voice of the set that can be combined to generate word, phrase etc. represents.Language model distributes a series of words
The probability that language will occur together in specific sentence or phrase.Voice sequence is converted into the intelligible word of language model by dictionary
Language.
