Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with specific examples, but not as a limitation of the present invention.

[0038] The Chinese voice interactive non-inductive control system based on Raspberry Pi edge computing of the present invention includes an edge terminal, a mobile terminal, an external control module and an edge computing detection and scheduling module; To elaborate:

[0039] Such as figure 1 As shown, the hardware system uses the Raspberry Pi as the mobile control terminal and the Internet of Things interface device, including the voice device module and the speech synthesis module, which has the advantage of being common to other Internet of Things modules on the market. The external control module adopts the I2C bus communication method , connected with drones and smart home interfaces; the edge end uses an X86 edge server to recognize speech through the end-to-end deep neural network MASR, and performs speech s...

Abstract

The invention discloses a Chinese voice interaction non-inductive control system based on Raspberry Pi edge calculation and a method thereof, and the system comprises an edge end, a mobile end, an external control module, and an edge calculation detection and scheduling module. According to the invention, the sizes of a speech recognition model and a speech synthesis model are small; the edge calculation and offline work can be realized, the equipment is directly deployed in mobile terminal equipment without depending on a network, the functions of voice synthesis and voice recognition can berealized under an offline condition, the problems of voice recognition and interaction functions under severe conditions such as unsmooth network or attack are solved, and the function of Chinese voice recognition interaction under a severe environment is realized.

Description

technical field [0001] The invention belongs to the field of computer technology, and relates to speech recognition technology, in particular to a Chinese speech interaction senseless control system and method based on raspberry pie edge computing. Background technique [0002] Speech recognition is to convert a piece of speech signal into corresponding text information. The system mainly includes four parts: feature extraction, acoustic model, language model, dictionary and decoding. In order to extract features more effectively, it often needs to be collected. The sound signal is preprocessed by filtering, framing, etc., and the signal to be analyzed is extracted from the original signal; after that, the feature extraction work converts the sound signal from the time domain to the frequency domain to provide a suitable feature vector for the acoustic model; In the model, the score of each feature vector on the acoustic feature is calculated according to the acoustic charac...
