Could you build this?
Partial Building an Android floating window UI is straightforward, but real-time on-device audio capture, low-latency multilingual ASR, and translation pipeline require specialized mobile ML optimization.
What it would actually take: The app requires an Android native stack (Kotlin/NDK) using Android's MediaProjection API for system audio capture, alongside quantized on-device ASR models (e.g. Whisper.cpp / Sherpa-ONNX) and a translation engine. The difficult parts are streaming audio without latency, optimizing memory and NPU/GPU inference to avoid thermal throttling, and synchronizing floating overlay subtitles across arbitrary Android apps.
