提出了一种基于骨导的高噪声环境下语音采集方案。在同步采样条件下，从时域和频域两个方面比较了骨导和气导在抗噪声性能上的差异。除了高频损耗外，所提出的方案实现了更好的性能。为了解决这一问题，提出了一种基于LMS自适应滤波器的均衡方法。分析结果表明，均衡后语音的频率上限范围增大。
A novel voice collection scheme based on bone-conduction in the high-noise environment is proposed in this paper. On the condition of synchronic sampling, the difference between bone-conduction and air-conduction on terms of anti-noise property is compared in the time and frequency domains. Better performance is achieved in the proposed scheme except for the high-frequency loss. In order to solve the problem, equalization based on LMS self-adaptive filter is introduced. The analysis results indicate that the upper limit frequency range of the equalized speech is increased.
