Could you build this?
No The product is a quantized streaming speech recognition model running in real time on an ESP32-P4 microcontroller. Building that requires embedded ML optimization, model quantization, and hardware-specific kernels that vibe coding cannot provide.
What it would actually take: A real version needs a streaming transducer model trained or converted for on-device use, quantized to 2 and 4 bits, and an inference engine tuned to the ESP32-P4 vector instructions and memory layout. It also needs audio front-end and real-time scheduling on the chip. This takes embedded ML and DSP engineers, plus the board and training data.
