Speech as a feedback modality for smart objects

One part of the vision of ubiquitous computing is the integration of sensing and actuation nodes into everyday objects, clothes worn on the body, and in large numbers into the environment. These augmented environments require novel types of interfaces that provide for naturalistic and adaptive interaction depending on user context. In this paper, we investigate the use of speech synthesis on sensor nodes that may be integrated into smart objects. We evaluate the so-called Wireless Voice Node, a small, wireless sensor node with the ability to generate voice output as a novel feedback modality for applications for ambient intelligence. As an example, we present the design and implementation of a speaking doll integrating this node. Using voice output from the doll we aim at using speech synthesis to improve the playing experience of children.
