Services of personalized TTS systems for the Mandarin-speaking speech
impaired are rarely mentioned. Taiwan started the VoiceBanking project in 2020,
aiming to build a complete set of services to deliver personalized Mandarin TTS
systems to amyotrophic lateral sclerosis patients. This paper reports the
corpus design, corpus recording, data purging and correction for the corpus,
and evaluations of the developed personalized TTS systems, for the VoiceBanking
project. The developed corpus is named after the VoiceBank-2023 speech corpus
because of its release year. The corpus contains 29.78 hours of utterances with
prompts of short paragraphs and common phrases spoken by 111 native Mandarin
speakers. The corpus is labeled with information about gender, degree of speech
impairment, types of users, transcription, SNRs, and speaking rates. The
VoiceBank-2023 is available by request for non-commercial use and welcomes all
parties to join the VoiceBanking project to improve the services for the speech
impaired.
