Embodiment Construction

[0024] The present invention is further described in conjunction with the following examples.

[0025] like figure 1 and 2 As shown, the voice interactive speaker in this embodiment reduces the echo cancellation error and accurately acquires the human voice in the case of interference from the speaker itself through the following steps.

[0026] The adjustment range of the playback volume of the voice interactive speaker is 0 to 100, and the playback volume is divided into 20 volume intervals according to the preset volume adjustment gradient 5 (the specific volume adjustment gradient and the number of volume intervals can be determined according to the actual situation of the speaker divide), and the maximum volume of each volume interval is used as the playback volume of the volume interval. Among them, it can be designed that the larger the playback volume, the smaller the volume range included in the preset volume adjustment gradient, so that more precise adjustments can...

Abstract

The invention relates to the technical field of intelligent loudspeakers, in particular to a computer readable storage medium and a voice interaction loudspeaker box utilizing the readable storage medium. The medium stores a computer program, and the computer program can be executed by a processor of the voice interaction loudspeaker box. According to the voice interaction loudspeaker box, reference parameters are set for correcting echo errors of the loudspeaker box at different sound volumes, the obtained corresponding relationship between an actual audio signal directly output by a main controller and the external echo collected by a microphone array is more accurate, therefore human voices can be more accurately obtained, the loudspeaker box can recognize a waking command according tothe more accurate human voices received by the loudspeaker box, and the waking rate of the loudspeaker box is increased.

Description

technical field [0001] The invention relates to the technical field of smart speakers, in particular to a computer-readable storage medium and a voice interactive speaker using the medium. The medium stores a computer program, and the computer program can be executed by a processor of the voice interactive speaker. Background technique [0002] With the rapid development of artificial intelligence and voice interaction technology, smart speakers have become a new hot spot in the market. Overseas giants represented by Google, Amazon, and Apple, as well as domestic companies such as Xiaomi, Himalaya, Baidu, and Tencent, are actively deploying smart speaker products . In China, due to the fierce price competition, the hardware design of smart speakers is gradually simplified due to cost constraints. The echo signal of the speaker makes the human voice wake-up command recognized by the speaker have a large error, which reduces the probability of the speaker being woken up. Co...
