摘要

本文提出了一种提取语音特征用于G. 729编码语音内容完整性验证的方法，该方法可以最大限度地降低计算成本并减小特征的大小。实验结果表明，该方法对语音传输中常见的再压缩、音量变化、重采样和转码等操作具有较强的鲁棒性，并且能够区分内容保留操作和恶意修改操作，在篡改检测方面表现良好。

Content Integrity Verification for G.729 Coded Speech

This paper proposes a method to extract speech features for content integrity verification of G. 729 coded speech, which could minimize the computation cost and reduce the sizes of the features. Experiments results show that the method is robust to common operations in speech transmission such as recompression, volume changing, re-sampling and transcoding, and also does well in tamper detection for its ability to distinguish content preserving operations from malicious modifications.
