本文研究了骨传导语音的音高特性。在不利条件下，语音信号的基音确定无法达到预期的准确度。骨导语音对环境噪声具有鲁棒性，并且在较低频谱区域具有规则的谐波结构。这两个特性使其非常适合音高跟踪。文献中很少有关于骨导语音的报道，以方便从同时记录的空气传导语音中检测和去除不需要的信号。在本文中，我们表明，即使在高噪声环境中，骨导语音也可以用于鲁棒的基音确定，这在许多实际语音通信应用中非常有用，例如语音增强、语音/说话人识别等。
This paper investigates the pitch characteristics of bone conducted speech. Pitch determination of speech signal can not attain the expected level of accuracy in adverse conditions. Bone conducted speech is robust to ambient noise and it has regular harmonic structure in the lower spectral region. These two properties make it very suitable for pitch tracking. Few works have been reported in the literature on bone conducted speech to facilitate detection and removal of unwanted signal from the simultaneously recorded air conducted speech. In this paper, we show that bone conducted speech can also be used for robust pitch determination even in highly noisy environment that can be very useful in many practical speech communication applications like speech enhancement, speech/speaker recognition, and so on.
