- [l] Aus der beliebten Serie "IT hinschmeißen und lieber Rosen züchten", heute: Das Gyroskop in eurem Smartphone ist sensibel genug für Spracherkennung.
We show that the MEMS gyroscopes found on modern smart phones are sufficiently sensitive to measure acoustic signals in the vicinity of the phone. The resulting signals contain only very low-frequency information (<200Hz). Nevertheless we show, using signal processing and machine learning, that this information is sufficient to identify speaker information and even parse speech.
Das Paper dazu. (Danke, Magnus)
