Abstract :
Bone conduction is useful as a tool to accomplish speech enhancement in noisy environments. In this paper, we design a linear phase impulse response filter to reconstruct the quality of the bone-conducted speech signal obtained from a speaker. The bone-conducted speech observation as well as the normal speech information is effectively utilized to design the filter. From experimental results, the properties of the reconstruction filter are investigated.
