Problems solved by technology

[0004] Due to the complexity of the algorithms involved, chips with few underlying resources and low communication rates are not capable of speech recognition tasks. Specific speech recognition chips on the market are required to make speech interactive speakers, but speech recognition chips are system-level chips, and the price is relatively high. , leading to an increase in the cost of voice interactive audio

Embodiment Construction

[0027] The invention is further described in combination with the following examples.

[0028] see figure 1 , figure 1 Is a schematic diagram of the hardware structure of the broadcasting system. figure 1 Among them, the broadcasting system is mainly composed of a speaker 1 and a mobile phone 2. The mobile phone 2 performs pluggable communication with the USB serial port socket 14 on the speaker 1 through a USB data cable.

[0029] The inside of speaker 1 is equipped with figure 2 The chip 11 shown is a non-voice recognition chip with USB serial port resources, and the price is cheaper than a voice recognition chip. Speaker 1 is also equipped with such image 3 The DAC decoder 12 and the speaker 13, the chip 11, the DAC decoder 12, and the speaker 13 are electrically connected in sequence. After the mobile phone 2 downloads the song, it transmits the song to the USB serial port base 14. The chip 11 forwards the song on the USB serial port base 14 to the DAC decoder 12 for decoding...

Abstract

The invention relates to the field of voice interaction, in particular to a voice interactive broadcast system and a loudspeaker box therein. The system stores a computer readable storage medium; theprogram in the computer readable storage medium can be executed by a chip in the system, and the system uses a mobile phone as an external device of the voice interactive loudspeaker box; a specific app is installed on the mobile phone, and the app runs the existing hardware resources of the mobile phone, thereby realizing a song downloading function and a voice recognition task which are supposedto be performed by the voice interactive loudspeaker box. Thus, the voice interactive loudspeaker box can leave out a built-in WIFI module, and the chip of the voice interactive loudspeaker box can also use a non-speech recognition chip with less underlying resources; and the cost of the voice interactive loudspeaker box is reduced when the voice interaction function of the loudspeaker box is also realized.

Description

Technical field [0001] The invention of the invention relates to the field of voice interaction, in particular to a voice interactive broadcasting system and a speaker in the system. A computer-readable storage medium is stored in the system, and a program on the computer-readable storage medium can be executed by a chip in the system. Background technique [0002] The voice interactive speaker mainly relies on a built-in chip to perform voice recognition on the user's voice collected by the microphone. After recognizing the name of the song spoken by the user, the corresponding song is downloaded from the network server through the built-in WIFI module. [0003] In the process of speech recognition, the chip needs to preprocess the user's speech, including multiple processing steps such as speech signal sampling, filtering and noise reduction, speech enhancement, feature extraction, etc., to extract one group or several from the speech signal waveform. The group can describe the c...
