Title:
オーディノイズリダクション回路、該オーディノイズリダクション回路を用いたスマートターミナル及び授業方法
Document Type and Number:
Japanese Patent JP6433073
Kind Code:
B2
Abstract:
The invention provides an audio noise reduction circuit, an intelligent terminal and a teaching method using this audio noise reduction circuit, where a dual microphone array is used for abatement of noise, ICA algorithm is used for blind source analysis; the audio noise reduction circuit is used to realize the extraction and separation of voice and improve the voice quality in noisy environment, so that the user can also obtain clear voice communication or recording effect even in noise environment; through real-time acquisition and recording of the audio information of teacher, the invention realizes the real-time recording of teaching voice data and solves the following problem: when the learning content is preset in the intelligent terminal, the learning experience is relatively monotonous, leading to unsatisfactory results of learning. Additionally, the invention also realizes the wireless sharing of high quality teachers and the real-time synchronous feedback in the process of teaching and learning, featuring such advantages as high interaction and good results of learning.
