Abstract
A speech recognition system includes a server, a data transmission interface and a speech recognition device. The speech recognition device builds a connection with the server through the data transmission interface. The speech recognition device includes a microphone, an output unit and a processing unit. The processing unit transmits received user information to the server through the data transmission interface to obtain a corresponding personal dictionary file. The personal dictionary file is generated according to history of speech recognition result and related data, which is used by others recently. The processing unit receives a voice signal to be recognized through the microphone and converts it into a digital characteristic file according to a voiceprint file of the user. The processing unit searches the personal dictionary file according to the digital characteristic file to obtain a speech recognition result for outputting through the output unit.
