AI Engineer Intern
Peppo AI
- Built an offline AI voice assistant on Raspberry Pi, connecting microphone input, speech recognition, local LLM response generation, and text-to-speech without cloud APIs.
- Improved response time from 20–25s to 4.48s by profiling the pipeline, tuning execution flow, and improving audio buffering on limited hardware.
- Added live local-model switching without restarting the system, making experiments and model comparisons faster.
