Abstract: TiogaVoice allows users to incorporate voice annotations into Tioga documents. The user interface is designed to be lightweight and easy to use, since spontaneity in adding vocal annotations is essential. Voice within a document is shown as a distinctive shape superimposed around a character, so that the document's visual layout and its contents as observed by other programs (e.g., compilers) are unaffected. Users point at text selections and use menus to add and listen to voice.

Simple voice editing is available: users can select a voice annotation and open a window showing its sound profile. Sounds from the same or other voice windows can be cut and pasted together, and a lightweight `dictation facility' that uses a record/stop/backup model can be used to record and incorporate new sounds conveniently. Editing is done largely at the phrase level (never at the phoneme level), representing the granularity at which editing can be done fastest and with least effort. The voice itself can be annotated with text. This and several other features have been designed to add speed and meaning to the editing process. The dictation facility can also be used when placing annotations straight into documents.
