Description
Summary:Voice input for command and control, message sorting by voice, and advanced low-bit-rate voice communications systems are discussed in relation to automatic speech recognition (ASR) technology applications. Several research efforts in the areas of ASR and speech synthesis technology, which forms the basis for voice input /output systems, are described for military airborne and ground-based applications. The success of the speech enhancement unit in noise reduction for both human and machine listeners is documented and shown to be indispensible for the ASR used in message sorting, and for many command-and-control applications in harsh environments. Two experimental low-bit-rate systems, one phonetically based, the other based on vector, or block quantization, are compared. ASR technology is shown to have the potential to increase the effectiveness of man-machine communications in a variety of military applications, such as equipment maintenance and computers. Further research is necessary to solve some basic problems.
