Product Design – Board development and production

Detecting people's swear words was the main goal of this project. Users can add specific words into the device memory, and it will react in case that anybody around it says the forbidden word. The reaction is notified with loud audio and bright light signal, which needs to be acknowledged by pressing the jar cover. The main challenge of the project was to get the speech recognition algorithm to work with a satisfying level of accuracy. The first decision was to use the offline Sphinx open-source library but this was later changed to the online Google voice recognition engine. The project was realized with a Raspberry Pi device. In order to enable the sound and light alarms, battery charging and other functionalities, a Raspberry PI add-on board was developed and produced.
