Keyword Detection (Live Audio + ML) — Zig

Source: apps/zig/example_keyword_live/src/main.zig | WASM demo not available — Zig 0.15 lacks wasm32-emscripten support

Real-time 'yes'/'no' keyword detection using on-board microphones and the TensorFlow Lite Micro micro_speech model. Audio is captured via I2S DMA, spectral features are extracted, and a neural network classifier runs inference every ~1 second.

Language-specific patterns

This example uses the ove Zig module with comptime feature detection (@hasDecl), generic types, defer-based cleanup, and catch-based error handling.
