2023's most interesting browser APIs
summary
Live demos show real browser capabilities: speech synthesis works locally but voices vary by device and language, and speech recognition requires permission and is inconsistently supported. Sensors (accelerometer, gyroscope, compass) drive interaction; a WebXR demo actually runs in-phone with Google Cardboard. Babylon.js and A‑frame combine camera, WebXR and sensor APIs into usable scenes. Heavy graphics and computation use Web Workers / Offscreen Canvas to avoid UI jank; raw JS compute in workers hits roughly ~60% of native C performance. Permissions and platform gaps remain.
