Building Performant Voice Agents in India

India's rapid growth in the voice agent sector has led to the strategic deployment of LiveKit Cloud's regional agents in Mumbai to minimize latency by co-locating AI models such as speech-to-text (STT), large language models (LLM), and text-to-speech (TTS) near voice agents. This setup reduces latency through optimized paths between users, agents, and models, demonstrating a significant improvement in performance compared to globally dispersed architectures. With a focus on serving India's diverse linguistic landscape, LiveKit supports a range of STT and TTS models catering to multiple Indian languages. It is recommended to use regional SIP trunk providers for telephony, ensuring local call quality, compliance with Indian regulations, and adherence to data residency requirements. LiveKit facilitates this process by offering co-located Deepgram STT models and a Mumbai-based deployment option, with fallbacks to other regions if necessary, while also providing guidance for optimal setup and compliance.
