Speech interfaces for mobile communications

This paper explains speech interfaces for mobile communication. Mobile interfaces have three important design rules: do not disturb the user's main task, work within the restrictions of user's ability, and minimize the resource requirements. Social acceptance is also important. In Japan, trial and regular services with speech interfaces in mobile environments have already been launched, but they are not widely used. They must be improved in mobile interfaces. The speech interface will not replace Web browsers, but should support and interwork with other interfaces. We also have to discover contents that suit speech interfaces.
