Embodiment Construction

[0053] The embodiment of the present invention discloses a voice recognition method, device, and electronic equipment, aiming to narrow the recognition range of the recognition engine according to the wake-up command while waking up the recognition engine through a wake-up command. The accuracy of speech recognition in the recognition range is higher, and therefore, the accuracy of speech recognition can be improved.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The present invention provides a voice recognition method and device, and electronic equipment, which receives voice input and recognizes the voice input as a wake-up command through a wake-up engine. While using the wake-up command to wake up the search engine, it determines the Compared with the entire recognition range of the recognition engine, the recognition range corresponding to the wake-up command is relatively small. Therefore, the recognition range of the recognition engine is narrowed. Compared with the larger recognition range, the recognition range is smaller. The accuracy of searching for targets in a small range is higher.

Description

technical field [0001] The invention relates to the field of pattern recognition, in particular to a voice recognition method and device, and electronic equipment. Background technique [0002] At present, speech recognition technology has been more and more widely used. Existing voice recognition methods applied to smart TVs usually first receive a wake-up command input by the user, wake up the voice control mode according to the wake-up command, and then search for objects according to the user's voice command, and present the searched objects to the user. For example, the smart TV receives the wake-up command "Voice Assistant" input by the user, that is, enters the voice control module, and then receives the user's voice "Journey to the West", and presents objects related to "Journey to the West" to the user. Usually, the search scope of the recognition engine is often massive, therefore, the search results obtained by the existing speech recognition method are often not...
