SMALL VOCABULARY TACTICAL SPEECH RECOGNIZER

THIS IS A PROPOSAL FOR THE DEVELOPMENT OF A SYSTEM FOR CONTINUOUS SPEECH RECOGNITION OF MODERATE SIZE VOCABULARIES WITH A LOW PERPLEXITY GRAMMAR, WHICH WOULD ACHIEVE ROBUST, HIGH PERFORMANCE UNDER SEVERE OPERATIONAL CONDITIONS. THE OBJECTIVE IS TO PROVIDE ADVANCED RECOGNITION CAPABILITIES FOR TACTICAL ENVIRONMENTS, SUCH AS MILITARY AIRCRAFT OR BATTLE MANAGEMENT, IN WHICH SPEAKERS ARE EXPOSED TO HIGH AMBIENT NOISE, AND SUBJECT TO PSYCHOLOGICAL AND PHYSICAL STRESS. THE MAIN EFFORTS IN THE DEVELOPMENT WILL CONSIST IN ELABORATING AND TESTING NEW METHODS OF HANDLING STRESS AND NOISE CONDITIONS, INTEGRATING THE IMPROVEMENTS INTO THE EXISTING HMM CONTINUOUS SPEECH RECOGNITION SYSTEM UNDER DEVELOPMENT AT DRAGON, AND DESIGNING AN ACTUAL PROTOTYPE. SPEECH RECOGNITION CAPABILITY IN REAL MILITARY ENVIRONMENTS. SPEECH INTERFACE TO COMMAND AND CONTROL BATTLE MANAGEMENT SYSTEMS. SMALL VOCABULARY VOICE DATA ENTRY APPLICATIONS IN NOISY ENVIRONMENTS.
