The+giant+leaps+in+language+technology+--+and+who%27s+left+behind+%7C+Kalika+Bali
access_time26 days ago
Thousands of languages thrive across the globe, yet modern speech technology -- with all of its benefits -- supports just over a hundred. Computational linguist Kalika Bali dreams of a day when technology acts as a bridge instead of a barrier, working passionately to build new and inclusive systems for the millions who speak low-resource languages. In this perspective-shifting talk, she outlines what happens when a language is omitted from the digital landscape -- and what can be gained when communities keep pace with the future.
