A novel voice collection scheme based on bone-conduction

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.
