We present you database Spanish ES voices, named AhoSLABI, which designed allow development new support technologies for this impairment. The primarily consists recordings 31 (27 males 4 females) pronouncing phonetically balanced sentences. Additionally, it includes parallel sentences 9 healthy speakers (6 3 facilitate tasks require small corpora, voice conversion or synthetic adaptation. Apart from sentences, sustained vowels set isolated words, can be valuable on analysis, diagnosis evaluation. paper describes main contents database, recording protocols procedure, well labeling process. acoustic characteristics speaking rate, durations recordings, phones silences, other compared those reduced voices. In addition, we describe an experiment improve performance ASR system speakers. resource will made available scientific community hope used life laryngectomees.
