線形予測法（LPC）残差波を用いて自然発声に近い音声を得るハンズフリー型電気式人工喉頭の開発

抄録

The Conventional electrolarynx (EL) restores the voice of people who have lost their voice, however, its voice sounds like a robot and it occupies user's one hand. Therefore, we developed a hands free wearable electrolarynx that improves the voice quality with the LPC residual wave as the vibration sound. Our device outputs the voice with a clearer formant on F3 and F4 than conventional EL does. Thus, we verified that the individuality of the voice can be expressed with our device.
