These will allow the old people or the high risk patients to benefit from medical supervision at home. We develop in collaboration with TIMC-IMAG laboratory, a system of telemonitoring in a habitat equipped with physiological sensors, position encoders of the person, and microphones. The originality of our approach consists in replacing the video camera monitoring, hardly accepted by the patients, by microphones which record the sounds in the apartment. The microphones carry out a multichannel sound acquisition system which, thanks to the sound information coupled with physical information, will enable us to identify any situation of distress. We describe below the practical solutions chosen for the acquisition system and the recorded corpus of situations.
