Problems solved by technology
Since the smart speakers in the room or meeting room are all in a fixed position, if the speaker is very close to the smart speaker, it will be better for the smart speaker to record and recognize the speaker's voice, and if the speaker is far away from the smart speaker , then the smart speaker records and recognizes the speaker's voice, there will be noise in the surrounding environment, and the signal-to-noise ratio of the voice signal will be very low
At the same time, multiple smart speakers working at the same time may respond to the same voice operation command, causing confusion

The invention discloses a smart device control method and system. More than one smart loudspeaker forms a smart loudspeaker array. The method comprises: a signal receiving delay difference between more than one smart loudspeaker is determined according to receiving situations for a same voice signal form a speaking person by the smart loudspeaker array; according to the signal receiving delay difference, a smart loudspeaker closest to the speaking person is determined; and the smart loudspeaker closest to the speaking person is controlled to respond to the voice signal. Therefore, the smart loudspeaker closest to the speaking person is determined to provide services for the speaking person, so that confusion caused by the simultaneous responses of multiple smart loudspeakers is avoided andthe power consumption of the smart loudspeakers is reduced.
Description
【Technical field】 [0001] The invention relates to computer application technology, in particular to an intelligent device control method and system. 【Background technique】 [0002] With the increasing maturity of speech recognition technology, more and more smart devices, such as smart speakers, are appearing in the market. Based on speech recognition technology, these smart devices provide consumers with a more convenient way of interaction. [0003] Current smart speakers usually have the function of recognizing sound and playing sound. In the prior art, there may be multiple smart speakers in a room or conference room to provide services for each speaker in the room or conference room, or to provide stereo or surround sound effects. Since the smart speakers in the room or conference room are all in a fixed position, if the speaker is very close to the smart speaker, it will be better for the smart speaker to record and recognize the speaker's voice, and if the speaker is...
