Multilingual Speech & Dialect Audio Data Collection in India
Building production Automatic Speech Recognition (ASR), Text-to-Speech (TTS), and Large Audio Models (LAMs) for global and regional deployments requires diverse, real-world voice data. India’s linguistic landscape — spanning 22 official languages and over 700 regional dialects — presents the ultimate benchmark for voice AI robustness.
