Redefining speech processing in the world’s most linguistically diverse nation.
Sarvam Audio: A Solution for India’s Linguistic Diversity
India’s linguistic richness is a marvel of human culture, boasting 22 official languages and hundreds of dialects. However, for AI, this presents a unique challenge. Conventional models like GPT-4o and Gemini 3 Flash often struggle with the common practice of code-mixing—the fluid blending of languages within a single conversation.
Sarvam Audio, built on the powerhouse Sarvam 3B model, is engineered specifically for this complexity. By utilizing an audio-first processing approach, it captures the subtle nuances of spoken communication across Hindi, Tamil, Telugu, Malayalam, Marathi, Bengali, and Indian English.
