Abstract

A device, computer program and method for outputting linguistic information. The voice output device, for example, includes an output information acquisition unit acquiring linguistic information and attribute information. Attribute information includes an attribute added to each linguistic element included in the linguistic information. A tactile pattern storage unit stores a predetermined tactile pattern corresponding to each linguistic element. A tactile pattern acquisition unit acquires the tactile pattern from the tactile pattern storage unit. A voice output unit reads aloud the linguistic elements and a tactile pattern output unit outputs, in parallel with reading aloud each linguistic element, the tactile pattern corresponding to the attribute added to the linguistic element, thereby allowing a user to sense the tactile pattern by the sense of touch.
