What happens to a voice assistant when a pressure cooker whistles mid-sentence? For most speech models, it falls apart. Thatโ€™s the problem the IndoML team set for 250+ teams at the IndoML 2026 Datathon. #IndoML2026 #SpeechAI #IndicLanguages #OpenData #ResponsibleAI

Truly inclusive AI takes more than good intentions. It takes sustained investment, collaboration, and the representation of every voice.
