Embodiment Construction

[0026] Design idea and design principle of the present invention:

[0027] 1. The purpose of the present invention is to eliminate the interference of the TV to the speech recognition device. Since it is to eliminate the interference of the TV, the audio signal of the TV will be removed from the mixed audio signal. Just imagine how difficult it is to separate a voice stream that has at least two voices mixed together, and then remove one of them. It's like pouring a bottle of blue ink and a bottle of red ink together, and then need to extract the red ink, which is probably impossible. However, in fact, in addition to the mixed signal, we can get the original signal before the mixed signal is generated, and this original signal is the reference signal.

[0028] 2. In the present invention, the reference signal is a clean TV audio signal without other audio, and the reference signal is used as a sample signal in "echo cancellation". As the name suggests, this signal is used in ...

Abstract

The invention discloses a device eliminating interference of a television on a speech recognition device, which comprises an audio receiver connected with the audio output end of the television, an HDMI audio and video separator connected with the HDMI audio and video output end of a set top box of the television, a video output unit, a first audio output unit, an audio selector, an echo elimination unit, a speech enhancement and noise reduction unit, an audio acquisition unit, a second audio output unit, and a playback module, wherein the echo elimination unit is connected with the audio selector, the audio acquisition unit and the speech enhancement and noise reduction unit; and the audio selector is connected with the HDMI audio and video separator and the audio receiver. Technologies such as television audio signal introduction, HDMI audio and video separation, television video restoration, television audio restoration, audio selection, echo elimination, speech enhancement and noise reduction and audio acquisition are combined together, a new technical scheme in which the television and an intelligent speech device can be used at the same time is formed, and the problem that the television and the intelligent speech device can be used at the same time can be solved.

Description

technical field [0001] The invention relates to the technical field of smart TVs, in particular to a device for eliminating interference from a TV to a voice recognition device. Background technique [0002] Fun smart speaker devices are becoming more and more popular now. The basic playback function of smart speakers is no different from ordinary speakers we use every day. After adding the concept of intelligence, this speaker is no longer just a device for playing music. It has more diverse ways of use and interaction with users. It is universally welcomed. For example, the user can say to the smart speaker: "Play me a song by Andy Lau", and the smart speaker will automatically play Andy Lau's song without manual selection of the song. The reason why smart speakers can read human speech depends on speech recognition technology. [0003] However, at present, whether it is the speech recognition module installed inside the smart speaker or the speech recognition module in...
