发明名称 HIGH QUALITY SPEECH CODER AT LOW BIT RATES
摘要 In a speech coder, a spectral parameter computer obtains a plurality of spectral parameters from an input speech signal and quantizes the obtained spectral parameters. Even at low bit rates, the speech coder requires relatively less computational effort and experiences less sound quality deterioration.
