Soundfree is creating a tool for people with hearing loss.
The tool recognizes important sounds. For example, a smoke detector or a baby's cry.
Johanna is a student at the University of Tartu. She has worked on improving the Soundfree tool.
It is difficult for the hearing impaired to record sounds. The algorithm does it for them.
The algorithm extracts the important part from the audio clip. Background noise is removed.
Johanna found that 10 audio clips are sufficient. Sometimes even 5.
The tool requires a microphone and a smart device. The microphone records sounds. The user receives a notification when the model detects an important sound.
The model recognizes sounds almost like a human. The sound of a doorbell and a smoke detector is easy to recognize. Knocking is more difficult.
Johanna continues her work. Her work helps the hearing impaired live better.
