Problems solved by technology
However, in the interaction, when the sound of the questions answered by the local students is picked up by the far-field microphone and transmitted to the remote classroom, since the sound transmitted to the remote classroom will be amplified by the power amplifier at the far end, the amplified sound will be heard in the remote classroom. The omnidirectional microphone in the end classroom is collected back, which leads to problems such as echo, the audio playback effect is poor, and the interactive audio experience is effective

Embodiment approach
[0041] As an embodiment of the present invention, the method also includes, as figure 1 As shown, when the second-level audio collection collects the first audio information and the second audio information, different channels are used for collection; the first audio information collection link and / or the second audio information collection link are cut off. The method includes, correspondingly cutting off the transmission channel of the first audio information and / or the second audio information in the secondary audio collection (ie figure 1 left and right channels in ).
[0042] As an embodiment of the present invention, the method for judging whether the audio information collected by the secondary audio collection is the first audio information or the second audio information includes collecting voice command information and judging according to the voice command information. The voice command can be a direct voice command, or it can be judged according to the voice keywo...

The present invention relates to a remote interaction method and system, including a first-level audio collection, a second-level audio collection, and a third-level audio collection; the first-level audio collection includes the collection of first audio information and the collection of second audio information; the second-level The audio collection includes collecting the audio information collected by the first-level audio collection, which is local audio information; the third-level audio collection includes collecting the audio information sent by the remote end; the first audio information and the second audio information collected by the second-level audio collection. The audio information does not perform local audio playback; the audio information collected by the third-level audio acquisition performs local audio playback; the second-level audio acquisition performs mutually exclusive acquisition of the first audio information and the second audio information at the same time; Part or all of the first-level audio information collected by the second-level audio collection is echo-cancelled before being sent to the remote end. Compared with the prior art, the audio quality in the remote audio interaction process can be effectively guaranteed, and a better audio playback effect can be achieved.
Description
technical field [0001] The invention relates to the field of remote interaction, in particular to a remote interaction method and system requiring remote interaction such as teaching and conferences. Background technique [0002] The traditional on-site teaching method, because students can directly face the teacher, the classroom atmosphere is most likely to be driven by the teaching teacher, and can have more interactions. Therefore, the traditional on-site teaching method has always been the most popular, teaching The most effective way of teaching. With the development of the information age, the development of the Internet and the shortage of effective teaching resources, limited by space and time, only the traditional teaching method can no longer meet people's learning needs. A considerable number of learners study through the Internet. The method can be recorded video or remote online education, but both the recorded video and remote online education have the intera...
