METHOD AND APPARATUS FOR ENCODING SPEECH

摘要

METHOD AND APPARATUS FOR ENCODING SPEECH In a speech encoder a Fourier transform of the speech is provided. The Fourier transform is equalized by normalizing the spectrum coefficients to a curve which approximates the shape of the spectrum. Both the curve and the equalized spectrum are encoded. Preferably, only a baseband of the normalized spectrum is encoded and that baseband is repeated in the decoder.
