  This paper presents a HMM-based speech recognition engine and its integration
into direct manipulation interfaces for Korean document editor. Speech
recognition can reduce typical tedious and repetitive actions which are
inevitable in standard GUIs (graphic user interfaces). Our system consists of
general speech recognition engine called ABrain {Auditory Brain} and speech
commandable document editor called SHE {Simple Hearing Editor}. ABrain is a
phoneme-based speech recognition engine which shows up to 97% of discrete
command recognition rate. SHE is a EuroBridge widget-based document editor that
supports speech commands as well as direct manipulation interfaces.
