VIVOS is a free Vietnamese speech corpus consisting of 15 hours of recording speech prepared for | |
Vietnamese Automatic Speech Recognition task. | |
The corpus was prepared by AILAB, a computer science lab of VNUHCM - University of Science, with Prof. Vu Hai Quan is the head of. | |
We publish this corpus in hope to attract more scientists to solve Vietnamese speech recognition problems. | |
