摘要： Activity is determined for each frequency band in a frame, and when it is determined that an activity-OFF state has not continued for a predetermined number of times for preceding frames, normal coding processing is performed for the frequency band. When it is determined that the activity-OFF state has continued for the predetermined number of times or more, DTX coding is performed for the frequency band. After this processing has been performed for all of the bands of one frame, a total power of the one entire frame and the power of the band or bands to which the DTX coding is applied are calculated. Subsequently, a new target bit value is calculated based on a ratio of the total power of the one entire frame and the power of the band or bands to which the DTX coding is applied.

摘要： A voice/music determining apparatus is configured to calculate first feature parameters for discriminating between a voice signal and a musical signal; and calculate second feature parameters for discriminating between a musical signal and a background-sound-superimposed voice signal. A first score is calculated to indicate likelihood that the input audio signal is a voice signal or a musical signal as a sum of weight-multiplied first feature parameters. A second score is calculated to indicate likelihood that the input audio signal is a musical signal or a background-sound-superimposed voice signal as a sum of weight-multiplied second feature parameters. It is determined whether the input audio signal is a voice signal or a musical signal on the basis of the first score. Further, it is determined whether the musical signal is the input audio signal is a background-sound-superimposed voice signal on the basis of the second score.
