Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The voice processing method provided by the present invention specifically relates to a smart home system, such as Figure 1a As shown, the smart home system includes a smart speaker 100 and a smart home device 120. The smart speaker 100 is used to collect voice signals, and the voice signals include various voice signals that the smart speaker 100 can collect in the space where it is located. . According to the collected voice signal, the smart speaker 100 performs voice interaction with the user 130 alone, wherein the user 130 sends the voice signal to the smart speaker 100 according to his own needs; or communicates with the smart home device 120 to assist the smart home device 120 Perform voice interaction with the user 130, wherein the smart home device 120 includes, but is not limited to: a smart TV, a pr...

Abstract

The invention discloses a voice processing method applied to a smart loudspeaker box. The method comprises: when a smart loudspeaker box is switched to be in a voice collection accessory mode, a soundaccompaniment signal sent by a preset intelligent household device is set to be an echo cancellation self-noise reference signal; according to a preset buffer area setting algorithm, a buffer area isset to store the echo cancellation self-noise reference signal of the corresponding retardation time length; and on the basis of the echo cancellation self-noise reference signal stored in the bufferarea, echo cancellation self-noise processing is carried out a voice signal collected by the smart loudspeaker box. In addition, the invention also discloses a smart loudspeaker box and a readable storage medium. Therefore, the awakening rate and recognition rate for the far-field voice by the smart loudspeaker box serving as the voice collection accessory of the intelligent household device areincreased.

Description

technical field [0001] The invention relates to the field of smart speakers, in particular to a voice processing method, a smart speaker and a readable storage medium. Background technique [0002] At present, far-field voice-interactive smart speakers on the market are mainly used as a voice-interactive smart speaker alone. Although some smart speaker products have voice command control for other smart home devices such as smart TVs, such as controlling the switch on and off of the TV, Volume adjustment, etc., but this is only limited to simple command control. When a smart speaker is used as a voice collection accessory for a smart home device, the audio signal sent by the smart home device to the smart speaker will interfere with voice wake-up and recognition. Self-noise signals affect the wake-up rate and recognition rate of far-field voices by smart speakers. [0003] The above content is only used to assist in understanding the technical solution of the present invent...
