Anordnung zur harmonischen Sprachcodierung.

摘要

A harmonic coding arrangement where the magnitude spectrum of the input speech is modeled at the analyzer (120) by a relatively small set of parameters and, significantly, as a continuous rather than only a line magnitude spectrum. The synthesizer (160), rather than the analyzer, determines the magnitude, frequency, and phase of a large number of sinusoids which are summed to generate synthetic speech of improved quality. Rather than receiving information explicitly defining the sinusoids from the analyzer, the synthesizer receives the small set of parameters and uses those parameters to determine a spectrum, which, in turn, is used by the synthesizer to determine the sinusoids for synthesis.
