These recordings are from a panel or presentation, in which the VoxWave team explained VOCALOID to the French community.
This video also has English subtitles available.
For those of you who are not yet acquainted with ALYS, she is a new VOCALOID being developed by VoxWave, bilingual in French and Japanese.
Her artwork has been illustrated by Saphirya, the winner of her design contest, which received over 200 entries. Her voice provider will be Poucet, the popular YouTaite (YouTube-based Utaite).
Given this conference informing the French community about VOCALOID, I think it would be safe to say that we will be getting more information on ALYS soon, so stay tuned!
