Fear/voice chatbot

Banuri Koushik Reddy requested to merge fear/voice-chatbot into main

Summary This MR implements comprehensive internationalization (i18n) and localization (l10n) across the application, establishing Telugu as the primary default language. It also completes the "Voice-to-Voice" loop for the AI assistant, relocating the voice interface to the chatbot area for a more integrated user experience.

Key Changes

  1. Internationalization (i18n) & Localization (l10n)
  • Default Language: Updated App.jsx to initialize the application in Telugu ('te').
  • Expanded Translation Schema: Updated src/i18n/ (English, Telugu, Hindi) to include new keys for the AI Assistant, including bot names, greetings, and action tooltips.
  • Dynamic UI Updates: Refactored the "Kisan Sahayak" chatbot to dynamically switch its greeting message and interface labels whenever the global language state changes.
  1. Voice Assistant Relocation & Automation
  • Relocation: Moved the microphone interface from the main SearchBar to the BotAssistant header to provide a focused AI interaction point.
  • Hands-Free Interaction: Implemented automated message dispatch. When a user speaks, the transcript is automatically sent to the AI (Groq/Gemini) without requiring a manual click of the "Send" button.
  • Text-to-Speech (TTS) Integration: Added a "Voice-Out" feature where the bot automatically reads its response aloud in the user's selected language (Telugu, Hindi, or English) if the query was initiated via voice.
  1. UI/UX Improvements
  • Button Discoverability: Redesigned the voice assistant button in the chatbot header to be larger and more prominent (High-contrast white square).
  • Visual Feedback: Added pulsing animations and dynamic placeholder text ("Listening...") to indicate active voice recording states.

Technical Notes

  • Exclusively Groq/Gemini: The AI service now supports high-speed Groq (Llama 3.3) with a seamless fallback to Gemini.
  • Rate-Limit Protection: All AI and data requests continue to use the centralized apiClient queue to prevent 429 errors.
  • Browser Compatibility: Voice features are optimized for Web Speech API compatible browsers (Chrome/Edge).

Testing Instructions

  1. Verify the app loads in Telugu by default.
  2. Open the chatbot and verify the greeting is in Telugu.
  3. Click the microphone icon, ask a question in Telugu, and verify the bot responds and speaks back in Telugu.
  4. Switch the language to English via the header globe icon and verify the chatbot greeting updates instantly.
