This paper describes a speech-input interface function, called speech shift, that enables a user to specify a speech-input mode by simply changing (shifting) voice pitch. While current speech-input interfaces have used only verbal information, we aimed at building a more user-friendly speech interface by making use of nonverbal information, the voice pitch. By intentionally controlling the pitch, a user can enter the same word with it having different meanings (functions) without explicitly changing the speech-input mode. Our speech-shift function implemented on a voice-enabled word processor, for example, can distinguish an utterance with a high pitch from one with a normal (low) pitch, regard the former as voice-command-mode input (such as file-menu edit-menu commands) the latter as regular dictation-mode text input. Our experimental results from twenty subjects showed that the speech-shift function is effective, easy to use, a labor-saving input method.
