VoiceCAD - a simple voice controlled drawing system (1994)
What you see on the screen has been drawn by means of VoiceCAD, a simple system for demonstrating voice command controlled tools. The system employed a speaker-independent isolated-word recogniser and was based on the application of continuous density hidden Markov models (HMM). The system was developed in 1994 as a demostration tool and that time run on a PC (386/33) in real time.
