Continuous Voice Control

A voice interaction paradigm in which vocal parameters such as pitch, loudness, vowel quality, and timbre are used to provide smooth, proportional, real-time control of a system, as opposed to discrete voice commands that trigger specific actions. Continuous voice control is analogous to the difference between a joystick (continuous) and a button panel (discrete) — it allows users to smoothly steer a cursor, control robotic movements, or adjust parameters by varying their voice in real time. This approach does not depend on language or vocabulary, making it language-independent and usable by people who may not have intelligible speech. Continuous voice control is particularly relevant for assistive technology because it provides a richer control channel than discrete commands while requiring only the ability to produce vocal sounds.
