Problems solved by technology

[0004] However, if figure 1 As shown, in the actual voice interaction scene, in addition to the voice of the target object, there are generally many unfavorable acoustic factors such as equipment echo, voice of non-target speakers, external noise interference, room reverberation, etc.
Therefore, the original sound received by the sound pickup device is a speech signal with noise and low signal-to-noise ratio, which is not conducive to the processing of the speech recognition algorithm, resulting in the inability to perform effective human-computer speech interaction
[0005] For the above problems, no effective solutions have been proposed so far

Embodiment Construction

[0031] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0032] Considering that if the original audio signal collected by the microphone array of the smart device can be enhanced, noise signals such as device echo, non-target speech, and environmental noise can be suppressed, thereby improving the signal-to-noise ratio of the target speech, then speech recognition can be effectively improved. ...

Abstract

The invention provides a speech recognition method, intelligent equipment and an intelligent television. The method comprises the steps of separating original speech data into one or more paths of speech data; determining a confidence level of each path of separated speech data; and performing speech recognition on the speech data with the highest confidence level. According to the method, influences of noise on the speech data can be reduced, the problem that at present speech recognition accuracy is not high due to existence of interference sound such as noise and the like is solved, the speech data can be accurately recognized, and more effective human-computer interaction can be performed.

Description

technical field [0001] The present application belongs to the technical field of the Internet, and in particular relates to a voice recognition method, a smart device and a smart TV. Background technique [0002] With the development of computers, the Internet, mobile Internet, and the Internet of Things, smart devices (such as mobile phones, computers, smart homes, smart robots, etc.) are used more and more frequently. In the past, a single human-computer interaction method based on keyboard, mouse, remote control, etc. has been unable to meet the demand for smart device control. Correspondingly, the demand for voice recognition and voice control has become more and more extensive, and voice interaction will also become a A wider range of human-computer interaction. [0003] In human-computer voice interaction, smart devices convert voice commands into text through voice recognition technology, and then understand the intent of the command through semantic understanding te...
