High quality harmonic excitation linear predictive speech coding at 2 kb/s
The paper presents a high quality harmonic excitation linear predictive (HE-LPC) speech coder operating at 2 kb/s based on a harmonic excitation model with two bands. The system incorporates novel features such as: combined pitch detection; residual harmonic matching voicing determination; extraction and interpolation of residual harmonic magnitudes. Subjective listening tests indicate that this coder has the same quality as that of the Federal Standard MELP (mixed excitation linear prediction) coder at 2.4 kb/s, whether the training database is from Chinese or English.
