What is it about?
This paper presents an experiment with seniors and people with visual impairment in a voice-controlled smart home using the SWEET-HOME system. The experiment shows some weaknesses in automatic speech recognition which must be addressed, as well as the need of better adaptation to the user and the environment. Indeed, users were disturbed by the rigid structure of the grammar and were eager to adapt it to their own preferences. Surprisingly, while no humanoid aspect was introduced in the system, the senior participants were inclined to embody the system. Despite these aspects to improve, the system has been favourably assessed as diminishing most participant fears related to the loss of autonomy.

Why is it important?
The autonomous SWEET-HOME system aims at helping old people living alone at home. It was evaluated by its potential users (old healthy persons and visually impaired people) because the social acceptance is very important . Without acceptance a system could not be helpful.
Perspectives
New research are in progress to define and develop, in conjunction with end users, the features of a distant voice controlled home automation system that will adapt to the user and that can be used in real conditions (noise, presence of several people).
