A developer has successfully implemented a 13.1 million parameter Automatic Speech Recognition (ASR) conformer model on a low-cost ESP32-S3 microcontroller. Through distillation and quantization, the model was reduced to fit within 14MB of flash memory and 256KB of SRAM, enabling it to transcribe 8 seconds of audio. While inference speed is still slow, it represents a significant improvement over previous attempts, and the developer advocates for more research into model efficiency to make AI more accessible on affordable hardware.
