在語言學習的情境中,學習者練習發音的過程,藉由耳朵接收到自己發出的聲音,瞭解自我的發音狀況,知覺自己實際發出來的聲音的正確性,對於學習如何發出正確的聲音,或是校正自己的發音,有很大的助益,然而在一般的學習環境,學習者聽到自己的聲音,會包含氣導音與骨導音的部分,氣導音為聲音由空氣介質傳播傳遞至耳膜的聲音,骨導音為聲音由人骨為介質傳遞至耳膜的聲音,然而骨導音與氣導音聲音是有所不同的,也因此學習者發音的過程,會聽見自己發出的骨導音干擾,學習者接收到失真的聲音,因而對自我發音的監控有負面的影響。 為了讓學習者能夠免除骨導音的干擾,而影響到自我發音的監控,本專利的技術藉由麥克風接收氣導音,再將氣導音藉由耳道式耳機來傳遞至耳膜,達到讓學習者免於骨導音的干擾之目的,此本藉由耳麥的方式可以讓學習者免於大部分的干擾,另外也有提供進階版本,使用主動式消除骨導音的技術,由骨導式麥克風接收學習者發音產生的骨導音,在接聲波訊號轉換為反向聲波,在經由骨導式耳機將反向聲波傳至人骨,抵銷原有之骨導音,來達到幾乎無骨導音干擾的效果,因此專業版本也可滿足正音或是歌手,需要很精準聽到自己的聲音的族群。 In language learning, learners hear their voices to understand their pronunciation in the learning process. To check the accuracy of pronunciation is helpful for making correct pronunciation or correcting pronunciation. However, learners are interrupted by the bond-conduction sound during the learning process. They hear the distorted sound and that is harmful to the pronunciation self-examination. For eliminating the interruption of bond-conduction sound, we use microphone to receive air-condition sound, then transfer the sound to ear drum through in-ear earphones. The design helps to prevent most interruption, and we also provide the technology to decrease the bond-conduction sound actively. We use bond-conduction microphone to receive bond-conduction sound, the sound is transferred to inverted sound, then transfer to human bond through bond-conduction earphones. Therefore, the technology provides advanced function for specific users who have the need to hear precise sound.
