AI Thermometer is an app that uses machine learning to listen to the sound of water being poured into a cup to tell you the temperature of the water. Sceptical? Hear the difference yourself!
Even without knowing it, most people can tell the temperature difference of water by listening to it (50>Carlos Velasco et. al.). This app makes this way of telling temperature more precise and can be used for e.g. brewing different teas at their intended temperatures. It is also a neat experiment hinting at the surprising abilities our AI overlords one day will have ;).
AI Thermometer was developed by Petter Säterskog. Axel Ericsson, Viktor Hallman and Erik Säterskog helped out with discussions and creating training data.
The accuracy is higher at high temperatures and the app is not intended to be used for temperatures < 50°C (122°F). The accuracy (RMSD) reaches ±3°C when tested under optimal conditions but is generally lower. The free version measures in multiples of 10°C (20°F), the upgrade allows for higher precision and also a visualized probability distribution and an 80% confidence interval.
This app needs one permission:
• Microphone access. This is so that the app can listen to the sound of pouring water.
