Problems solved by technology

[0005] In the context of Chinese language applications, choosing redundancies as wake-up words is very popular among users, and choosing redundancies-type wake-up words (such as "Tencent Tencent") has good wake-up performance. However, based on the currently provided wake-up word detection methods, Reasonable schemes have not been designed for redundant wake words, so in voice interactive devices, the detection performance of redundant wake words is poor

Embodiment Construction

[0048] The embodiment of the present application provides a method for speech recognition, a method and a device for detecting wake-up words, fully considering the pronunciation characteristics of the redundancies, and using the speech recognition model to calculate the score of each word in the redundancies. Only when the score meets the conditions can it be recognized as a wake-up word, thereby improving the performance of detecting redundancies-style wake-up words, with a higher wake-up rate and a lower false wake-up rate.

[0049]The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and not necessarily Used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein, for example, can be practiced in seq...

Abstract

The invention discloses an awakening word detectionmethod. The method is applied to the field of artificial intelligence, and particularly can be applied to the field of speech recognition. The methodcomprises the steps of acquiring speech information to be recognized, wherein the speech information to be recognized comprises a target word set that is composed of at least two repeated target wordsets, and each target word set comprises at least a target word; acquiring a target speech feature vector according to the speech information to be recognized; determining a target probability scoreset corresponding to the target speech feature vector via a speech recognition module; and if the target probability score set meets a speech awakening condition, determining that the speech information to be recognized comprises atarget awakening word that is one awakening word in the awakening word set. The invention discloses an awakening word detection device and terminal equipment. Accordingto the methods and device, the reiterative style awakening word detection performance is enhanced, the awakening rate is relatively high, and the mistakenly awakening rate is relatively low.

Description

[0001] This application is a divisional application of a Chinese patent application submitted to the China Patent Office on October 25, 2018, with the application number 201811253171.X, and the title of the invention is "a method for speech recognition, a method and device for detecting wake-up words". technical field [0002] The present application relates to the technical field of artificial intelligence, and in particular to a speech recognition method, a wake word detection method and a device. Background technique [0003] With the popularization of smart voice devices, human-computer interaction with smart devices through voice commands has become an important function. In voice interaction applications, users can wake up smart devices through voice wake words, so the wake word detection performance of smart devices has a significant impact on the human-computer interaction experience. [0004] At present, a method based on dynamic time warping (DTW) can be used for w...
