Although speech is a highly natural mode of communication, building robust and usable speech-based interfaces is still a challenge, even if the target user group is restricted to younger users. When designing for older users, there are added complications due to cognitive, physiological, and anatomical ageing. Users may also find it difficult to adapt to the interaction style required by the speech interface. In this chapter, we summarise the work on spoken dialogue interfaces that was carried out during the MATCH project. After a brief overview of relevant aspects of ageing and previous work on spoken dialogue interfaces for older people, we summarise our work on managing spoken interactions (dialogue management), understanding older people's speech (speech recognition), and generating spoken messages that older people can understand (speech synthesis). We conclude with suggestions for design guidelines that have emerged from our work and suggest directions for future research.
