## Summary

Bertrand Irrisou and Gerald Friedland of Audeme discuss their ASR Shield, a credit-card-sized Arduino add-on that enables offline, speaker-independent voice recognition without cloud dependency. They explain how the board uses an Allwinner A13 ARM Cortex-A8 processor running Linux to run acoustic and language models, allowing users to program hundreds of custom sentences via a simple Arduino library. The founders detail the technical challenges of audio front-end design, including automatic gain control and handling echo, while noting the system's ~3W power consumption and the necessity of adult-voice training data which affects recognition for children.
