Voice interaction method and system

The embodiment of the invention provides a voice interaction method. The voice interaction method includes the steps that a first audio signal is received, and an audio-signal decoding library prearranged on a hardware layer is called for decoding; when a decoding result of the first audio signal is a rousing word of a main rousing command, the main rousing command is sent to a software layer, andmonitoring of a second audio signal is started; the audio-signal decoding library is called for parsing the monitored second audio signal; when a decoding result of the second audio signal is a rousing word of a function command, the function command corresponding to the rousing word is sent to the software layer to carry out corresponding operations, and when the second audio signal cannot be parsed, the second audio signal is sent to a preset voice cloud processing platform, text information of the second audio signal is determined according to feedback of the cloud processing platform, thetext information is sent
