subtopic

RAG lookup and Hindi/Hinglish support

10 min applied15 min research2 curated resources

Add a lookup_faq tool that searches your FAQ documents (a small vector store) and returns the best answer in 1–2 sentences. Make the agent bilingual: a multilingual STT setting or an Indian-language STT, a TTS voice that speaks Hindi/Hinglish naturally, and a prompt rule to reply in the caller's language. Test 10 Hinglish calls.

Builds on: 4.3 Prepare the documents, 4.4 Generate the answer, 4.4 Sentence embeddings
