我们提出了一种新型的实用输入接口，用于识别非可听杂音(NAM)，即识别没有声带振动产生的不可听语音。我们利用医用听诊器的原理，研制了一种贴在皮肤上的麦克风附着器，找到了采集肌肉传导NAM声音振动的理想位置，并用NAM样本重新训练了声学模型。然后，使用Julius日语听写工具包，我们测试了实际使用该方法取代外部麦克风分析空气传导语音声音的可能性。
We propose a new style of practical input interface for the recognition of non-audible murmur (NAM), i.e., for the recognition of inaudible speech produced without vibration of the vocal folds. We have developed a microphone attachment, which adheres to the skin, applying the principle of a medical stethoscope, found the ideal position for sampling flesh-conducted NAM sound vibration and retrained an acoustic model with NAM samples. Then, using the Julius Japanese Dictation Toolkit, we tested the possibilities for practical use of this method in place of an external microphone for analyzing air-conducted voice sound.
