Embodiment Construction

[0045] In the speech recognition method in the prior art, when speech recognition is performed, speech recognition processing is usually performed on multiple sound frames obtained by dividing the sound data to be recognized at a fixed frame rate (Fixed Frame Rate, FFR). Since some of the divided sound frames do not include speech information, performing speech recognition processing on these non-speech frames that do not include speech information is not only meaningless for speech recognition, but also wastes computing resources. , to slow down the speech recognition speed.

[0046] In order to solve the above-mentioned problems in the prior art, the technical solution adopted in the embodiment of the present invention can save computing resources and increase the speed of speech recognition by selecting sound frames satisfying preset conditions from the sound data to be recognized for speech recognition. Improve user experience.

[0047] In order to make the above objects,...

Abstract

The invention provides a speech recognition method and a device thereof. The speech recognition method comprises the steps of subjecting obtained sound data to the framing treatment to obtain at least two voice frames; selecting a voice frame that meets a selection condition out of the above at least two voice frames; calculating the speech recognition score of the voice frame that meets the selection condition; on the condition that the calculated speech recognition score is greater than a preset score threshold, subjecting the obtained sound data to the voice recognition. According to the technical scheme of the invention, computing resources are saved and the speech recognition speed is improved.

Description

technical field [0001] The invention belongs to the technical field of voice recognition, in particular to a voice recognition method and device. Background technique [0002] Mobile terminals refer to computer equipment that can be used on the move, broadly speaking, including mobile phones, notebooks, tablet computers, POS machines, vehicle-mounted computers, etc. With the rapid development of integrated circuit technology, mobile terminals already have powerful processing capabilities, and mobile terminals are changing from a simple communication tool to a comprehensive information processing platform, which also adds a wider development space to mobile terminals. [0003] The use of a mobile terminal usually requires a certain concentration of the user's attention. Today's mobile terminal devices are equipped with touch screens, and users need to touch the touch screens to perform corresponding operations. However, when the user cannot touch the mobile terminal device,...
