THE USE OF DIGITAL COMPUTERS IN SPEECH ANALYSIS AND SYNTHESIS
Abstract
A new approach toward the goal of compressed digital speech communication is based on speech data reduction in successive stages. First, the voice signal is measured in a Vocoder type of analyzer and the output information digitized. The spectrum pattern data is then reduced by selecting the best approximations from a stored set of spectrum patterns, and reading out the pattern serial numbers. This data is further reduced by selection of the best approximations from a stored set of pattern sequences and pitch sequences. The serial numbers of the sequences are transmitted. At the receiver, an inverse process expands the information to a voice output. (Author)
