In this paper, we present novel speaking-aid systems based on one-to-many eigenvoice conversion (EVC) to enhance three types of alaryngeal speech: esophageal speech, electrolaryngeal speech, and body-conducted silent electrolaryngeal speech. Although alaryngeal speech allows laryngectomees to utter speech sounds, it suffers from the lack of speech quality and speaker individuality. To improve the speech quality of alaryngeal speech, alaryngeal-speech-to-speech (AL-to-Speech) methods based on statistical voice conversion have been proposed. In this paper, one-to-many EVC capable of flexibly controlling the converted voice quality by adapting the conversion model to given target natural voices is further implemented for the AL-to-Speech methods to effectively recover speaker individuality of each type of alaryngeal speech. These proposed systems are compared with each other from various perspectives. The experimental results demonstrate that our proposed systems are capable of effectively addressing the issues of alaryngeal speech, e.g., yielding significant improvements in speech quality of each type of alaryngeal speech. |
