METHOD AND DEVICE FOR QUANTIZING VOICE SIGNALS IN A BAND-SELECTIVE MANNER
摘要
The present invention relates to a method and device for quantizing voice signals in a band-selective manner. A voice decoding method may include inversely quantizing voice parameter information produced from a selectively quantized voice band and performing inverse transform on the basis of the inversely quantized voice parameter information. Thus, according to the present invention, coding/decoding efficiency in voice coding/decoding may be increased by selectively coding/decoding important information.
