Design of Song Ordering System Based on Speech Recognition

In this paper, the song-ordering system designed based on speech recognition uses STM32 single-chip microcomputer as the main control unit to realize the corresponding functions. The designed system includes the design of hardware and the realization of software functions. The rest have LD3320 speech recognition module, OLED display module, and voice broadcast module as song playback module. The working process is mainly completed by sending the protocol, that is, the voice recognition module receives the voice command, and the serial port sends the protocol to trigger the microcontroller control part. The system meets the following functions: it has the function of voice recognition and analysis, and completes the remote control of the corresponding tasks by recognizing voice commands; it realizes the basic voice song request function, which meets some basic requirements and can display the relevant information of the currently playing song.After continuous debugging and functional testing, the system successfully realized the functions of using voice to control the completion of song ordering, displaying the basic information of the song on the display screen, and successfully playing the song. Finally successfully completed a language song ordering system with stable operation, correct functions, convenient, quick and intelligent.
