An Automated Mood Diary for Older User’s using Ambient Assisted Living Recorded Speech

In this paper, we describe a system for recording of mood di aries in the context of an ambient assisted living and intelli gent coaching environment, which ensures privacy by design. The system performs affect recognition in speech features with out recording speech content in any form. We demonstrate re sults of affect recognition models tested on data collected in care-home settings during the SAAM project (Supporting Ac tive Ageing through Multimodal Coaching) using our custom designed audio collection hardware. The proposed system was trained using Bulgarian speech augmented with training data obtained from comparable mood diaries recorded in Scottish English. A degree of transfer learning of Scottish English speech to Bulgarian speech was demonstrated.
