摘要

传统的电喉(EL)可以恢复失声者的声音，但它的声音听起来像机器人，而且它占据了使用者的一只手。因此，我们开发了一种免提可穿戴式电喉，以LPC残波作为振动声来改善语音质量。我们的设备能够再现低于500赫兹的声音，接近基本频率，但从1700赫兹到4000赫兹，传统的EL连续显示的频率响应比我们的设备更接近用户声音的频谱。因此，发现基本频带的周期性声音比个性或音质更接近人类语言。

Development of a hands-free electrolarynx for obtaining a human-like voice using the LPC residual wave

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 was able to reproduce sounds below 500 Hz, which is close to the fundamental frequency, but from 1700 Hz to 4000 Hz, the conventional EL continuously showed a frequency response closer to the spectrum of the user's vocal sound than our device. Thus, the periodic sound of the fundamental frequency band was found to be closer to human speech than individuality or sound quality.
