Open Datasets: GigaSpeech 2 – 30,000 Hours of Southeast Asian Multilingual Speech Recognition Open Source Dataset Released
The term “Giga” originates from “gigantic,” reflecting the vast audio resources available on the internet. However, the quality of these audio resources varies significantly, and high-quality audio-text pairs are particularly scarce and expensive to annotate, especially for low-resource languages. GigaSpeech, a highly successful open-source English dataset, addresses this issue by providing thousands of hours […]
