Problems solved by technology

However, in the actual use process, the speaker of the sound box emits sound, which makes the sound box as a whole and the internal PCB board in a state of vibration, causing interference to the voice signal collected by the microphone. The invention patent application with the publication number CN107134286A discloses a The wireless audio playback method, music player and storage medium based on voice interaction, receive the user's control voice through the intelligent music player, connect the high-power speakers through wireless communication to play, set the receiving and playing devices separately, and reduce the impact of playing audio The effect of voice command recognition, but this method does not solve the impact of how to eliminate the vibration of the PCB board on the reception of voice signals when using an audio player to play audio. In this case, a low-power audio player can only be used as a controller use, it cannot be used as a player independently, which limits the use of the device

Embodiment 1

[0047] like figure 1 As shown, this embodiment provides a smart speaker audio playback method, including the following steps:

[0048] Step A: The smart speaker receives the wake-up voice and switches to the wake-up state. In the wake-up state, if the smart speaker is in the playback state, reduce the output volume of the smart speaker;

[0049] This embodiment is based on the wake-up voice to wake up the smart speaker. When the smart speaker is playing audio, it can actively reduce the playback volume after being awakened to facilitate receiving the user's subsequent voice commands, improve the recognition accuracy, and solve the impact of its own playback vibration on receiving control commands, thereby Enable smart speakers to effectively act as controllers and players, improving user experience.

[0050] The content of the wake-up voice is the identification name of the smart speaker, which can be defined by the user. The wake-up voice can switch the smart speaker from th...

Embodiment 2

[0068] The audio playback method provided by this embodiment includes the following steps:

[0069] A smart speaker audio playback method, comprising

[0070] Step i: the user speaks the wake-up voice of the smart speaker;

[0071] Step ii: The smart speaker receives the wake-up voice, switches to the wake-up state, and sends out a prompt message. In the wake-up state, if the smart speaker is in the playback state, reduce the output volume of the smart speaker;

[0072] Step iii: After the smart speaker sends out the prompt message, the user speaks the playback control voice that the smart speaker wants to execute;

[0073] Step iv: The smart speaker receives the playback control voice, extracts playback keywords based on the playback control voice, and analyzes the audio stream server address based on the playback keywords to generate a playback request;

[0074] Step v: The smart speaker accesses the corresponding audio streaming server based on the playback request;

Embodiment 3

[0078] base reference Figure 7 , based on the above audio playback method, this embodiment also provides a smart speaker audio playback device, including:

[0079] Wake-up module: used to receive the wake-up voice, switch to the wake-up state, and in the wake-up state, if the smart speaker is in the playback state, reduce the output volume of the smart speaker;

[0080] Play request generation module: used to receive playback control voice, analyze and generate play request;

[0081] Play request sending module: used to send the play request to the parsed audio stream server;

[0082] Audio stream data receiving module: used to receive the audio stream data returned by the audio stream server;

[0083] Play module: Play audio streaming data through smart speakers.

[0084] refer to Figure 8 , the play request generation module includes

[0085] Voice receiving and processing unit: used to receive sound information in the user's environment, and perform noise reduction p...

Abstract

The invention provides an intelligent sound box audio playing method. The method comprises the following steps that: A, an intelligent sound box receives wake-up voice and switches to a wake-up state, and in the wake-up state, if the intelligent sound box is in a playing state, the output volume of the intelligent sound box is reduced; B, the intelligent sound box receives playing control voice, extracts a playing keyword based on the playing control voice, and generates a playing request; C, an audio stream server is visited based on the playing request, and corresponding audio stream data are sequentially obtained from the audio stream server; and D, the intelligent sound box plays the received audio stream data. According to the intelligent sound box audio playing method and device, the electronic equipment and the storage medium of the invention, the playing volume is regulated and controlled based on the wake-up voice; the playing volume is actively reduced, so that the subsequent voice instruction of a user can be received conveniently, and the influence of playing vibration on receiving the control instruction is eliminated; different servers are accessed through a unified port, so that the use of a user is prevented from being influenced by a copyright problem, and the satisfaction is improved; and only keywords need to be detected, and error data are filtered out from the audio stream server level.

Description

technical field [0001] The invention relates to the technical field of smart speakers, in particular to an audio playback method, device, electronic equipment, and storage medium for a smart speaker. Background technique [0002] Smart speakers are a new type of smart electronic products, most of which have voice input functions and long-distance voice collection functions. By arranging multiple smaller MEMS microphones in a certain array, they are fixed on the PCB board inside the speaker. This enables the speaker to collect voices from various angles and directions very well. However, in the actual use process, the speaker of the sound box emits sound, which makes the sound box as a whole and the internal PCB board in a state of vibration, causing interference to the voice signal collected by the microphone. The invention patent application with the publication number CN107134286A discloses a The wireless audio playback method, music player and storage medium based on voi...
