Could you build this?
No Developing an ultra-compact (100 KB) wake-word engine and streaming on-device speech stack running in real-time on a Raspberry Pi Zero requires deep embedded ML, digital signal processing, and low-level C++/WASM optimization.
What it would actually take: This requires acoustic modeling research, int8/int4 model quantization, and custom C/C++ or Rust inference engines utilizing SIMD/NEON intrinsics. Engineers need deep expertise in embedded systems, digital audio processing, and cross-compilation across ARM, Android NDK, and WebAssembly.
