Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0047] The voice search optimization method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 is connected to an external communication network through a data network or a wireless network, or works offline. After acquiring the voice signal input by the user, the terminal 102 may perform matching analysis on the input signal (for example, the aforementioned voice signal) and a preset template. If the terminal 102 determines that there is a preset template matching the input signal after matching analysis, then ...

Abstract

The invention relates to a voice search optimization method. The method comprises: an input signal is obtained and a matched analysis is carried out on the input signal and a preset template; if one preset template matching the input signal exists, a search state of a WFST network is reset; according to the WFST network after search state resetting, pre searching is carried out on the preset template matching the input signal to obtain an optimized WFST network corresponding to the preset template; and on the basis of the optimized WFST network, searching of all frames of voice signals is completed to obtain a searching result. In addition, the invention also discloses a voice search system. When the input signal matches the preset template, the search state of the WFST network is reset; pre searching is carried out in the WFST network after search state resetting according to the preset template, so that the optimized WFST network is obtained; and according to the optimized WFST network, all frames of voice signals are searched and the searching result is outputted. Therefore, a problem of low identification accuracy in the traditional voice identification mode is solved; and thusthe voice identification accuracy is improved substantially.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice search optimization method, device and voice search system. Background technique [0002] With the continuous innovation of information technology, various smart devices are also being updated rapidly. Speech recognition technology, one of the popular technologies of many smart devices, is a typical representative of data information applications. Speech recognition technology can recognize a given speech into corresponding text information. Therefore, it is widely used in various intelligent interactive devices, such as the voice wake-up function and voice assistant functions of intelligent interactive devices. [0003] The traditional speech recognition method generally extracts the features of the input speech signal frame by frame, and calculates the corresponding classification probability according to the acoustic model. Complete the search of all speech...
