The Business Problem
Text chatbots fail to engage hands-busy users, needing high-performance voice-loop tech.
Research & Planning
Tested audio encoders latency to configure fast speech-to-text workflows.
Develop an Ionic Angular app connected to a Python Flask API and Gemini models.
Design & Architecture
Designed a minimal audio visualizer indicating active recording states.
Angular frontend, Flask API processing audio chunks, connected to Gemini models.
Implementation & Testing
Coded WebAudio buffers scripts, Flask transcription API hooks, and text-to-speech feedback.
Tested voice loop responses on mobile web browsers under multiple network speeds.
Deployment & Outcomes
Hosted frontend client on Vercel and Flask backend API on Render nodes.
Achieved sub-2s voice chatbot latency with high accuracy transcription.
Key Outcomes
- Voice response latency reduced under 2 seconds
- Word error rate (WER) dropped below 5%
- Supported 30+ translation languages natively
Lessons Learned
Uploading raw audio in OGG compression saved 60% bandwidth compared to WAV uploads.
The voice translation is fast and intuitive. It behaves like a real conversation.
