基于物理特征的音频相似度比对算法研究

针对电台播音需要将来自卫星的声音与拟发射的声音一致以保证播音安全,提出了一种基于物理特征的音频相似度比对算法.算法通过提取波形、包络、过零率等特征参数进行音频信号相似性的比较,并对比较结果进行融合,得出在不同环境下的待测音频相似性比较的优化方法,实验表明了该方法的有效性.

Audio comparison algorithm based on physical characteristics

In the light of the need for radio broadcasting,the sound from the satellite will be consistent with the sound to be transmitted to ensure the safety of broadcasting.This paper proposed an audio similarity comparison algorithm based on the physical characteristics and compared audio signal similarity by extracting the parameters like waveform,envelope and zero crossing rate to fuse the results of similarity comparison.At last,this paper summarized an optimization method under different environment for the similarity comparison of to be test audio,and showed the effectiveness of this method by the experiments.
