Description: 本程序用于测量增强语音与纯净语音的对数谱距离，用于语音增强。对数谱距离越小，表明增强语音与纯净语音越接近，增强语音质量越好；反之，则增强语音质量越差。-Calculates the average log-spectral distance between CLEAN and NOISY
signals. Frames are 25ms long with 60 percent (15ms) overlap, hamming
windowed. RS is the remove silence option (default: 0) if 1, the program
uses a Voice Activity Detector to find non-speech frames and eliminates
them from calculation of LSD. FS is the sampling frequency (Default
10KHz). Platform: |

Description: ITU-T G.722.2
国际电信联盟G.722.2建议书，2003年7月版。该建议书是语音通讯领域的压缩标准，被GSM，WCDMA，3GPP等采用，题目为16kbit下的宽带语音编码，使用自适应多率宽带编码。
内容主要有代数码激励线性预测编码(ACELP)，话音活动检测(VAD)等。-This Recommendation describes the high quality Adaptive Multi-Rate Wideband (AMR-WB)
encoder and decoder that is primarily intended for 7 kHz bandwidth speech signals. AMR-WB
operates at a multitude of bit rates ranging from 6.6 kbit/s to 23.85 kbit/s. The bit rate may be
changed at any 20-ms frame boundary.
Annex C includes an integrated C source code software package which contains the implementation
of the G.722.2 encoder and decoder and its Annexes A and B and Appendix I. A set of digital test
vectors for developers is provided in Annex D. These test vectors are a verification tool providing an
indication of success in implementing this codec.
G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP
specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector. Platform: |
