Problems solved by technology

[0006] The technology of the present invention solves the problem: to overcome the unified decoding method adopted by the traditional voice command control system, which may easily cause voice command response errors, or the problem of being unable to respond, the present invention provides a new key voice retrieval system and method, aiming at several specific Keywords are searched, and the reverse viterbi decoding scheme is adopted at the same time to save memory, the response speed is within 100ms, the memory usage is within 9k, and the calculation amount is within 29Mips

Embodiment Construction

[0030] Such as figure 1 As shown, it is the UML sequence diagram of the whole system, figure 2 as a flow chart; from figure 1 It can be seen that the system consists of three modules, 1: engine interface part, 2: front-end voice processing module, 3: decoder module.

[0031] In the engine interface part, you can see the API of the entire engine, including: a, initialization, b, parameter setting, c, input audio interface, d, data processing interface, e, reset interface;

[0032] a. In the initialization interface, it is necessary to pass in the first memory address of the application, the first address of multiple wake-up resources, and the corresponding resource space size. The interface internally realizes the initialization of the memory address, completes the memory allocation of the front-end and the decoder, and completes the front-end voice processing. The parameters include the frame length (25ms in the embodiment of the present invention), the frame movement lengt...

Abstract

The invention discloses a keyword speech retrieval system and a keyword speech retrieval method. The keyword speech retrieval system comprises a multi-awakening resource module, a speech preprocessing module and a speech decoding module. According to the system and the method, retrieval is performed for several specific keywords, and an inverted-order Viterbi decoding scheme is adopted, so that memory is saved, response speed is within 100ms, memory usage is within 9k, and operation quantity is within 29Mips.

Description

technical field [0001] The invention relates to the technical field of voice signal processing, in particular to a method for using voice signal processing in the retrieval of certain keyword voices in continuous voices. Background technique [0002] It has become an urgent need for the current application and development of information technology to realize the humanized and intelligent effective interaction between man and machine, and to build an efficient and natural man-machine communication environment. Especially in recent years, with the popularity of wireless communication networks, intelligent portable mobile devices have played an increasingly important role in people's lives. Voice interaction is favored as the most natural and human interaction method, which improves the efficiency of human-computer interaction. [0003] Nowadays, in a society with highly developed technology, people have higher and higher requirements for the quality of life and higher driving...
