发明名称 Method and system for reducing effects of noise producing artifacts in a voice codec
摘要 <p>There is provided a method of reducing effect of noise producing artifacts in a speech signal. The method comprises obtaining (310) a plurality of incoming samples of a speech subframe; summing (310) an energy level for each of the plurality of incoming samples to generate a total input level; comparing (320) the total input level with a predetermined threshold; setting (340) a gain value as a function of the total input level, where the gain value is between zero (0) and one (1), and where the function results in a lower gain value when the total input level is indicative of a silence area than when the total input level is indicative of a non-silence area; and multiplying (350) the plurality of incoming samples of the speech sub frame by the gain value.</p>
