An electrolarynx is a speaking aid device to artificially generate excitation sounds to help laryngectomees produce electrolaryngeal (EL) speech. Although EL speech is quite intelligible, its naturalness significantly suffers from the unnatural fundamental frequency (F0) patterns of the mechanical excitation sounds. To make it possible to produce more naturally sounding EL speech, we have proposed...
An electrolarynx is a device that artificially generates excitation sounds to produce electrolaryngeal (EL) speech. Although proficient laryngectomees can produce intelligible EL speech by using this device, it sounds quite unnatural due to the mechanical excitation. To address this issue, we have proposed several EL speech enhancement methods using statistical voice conversion and showed that statistical...
In human-to-human speech communication, various barriers are caused by some constraints, such as physical constraints causing vocal disorders and environmental constraints making it hard to produce intelligible speech. These barriers would be overcome if our speech production was augmented so that we could produce speech sounds as we want beyond these constraints. Voice conversion (VC) is a technique...
