Recent Advances in Speaker Recognition

介绍了话者识别技术的国内外最新研究进展情况．文章概要地介绍了所研究的题目和内容，重点讨论了近来引起普遍关注和兴趣的新探索和新技术．其中包括ＶＱ和Ｅｒｇｏｄｉｃ－ＨＭＭ方法、与文本无关的识别方法、文本提示型识别方法、参数／距离标准模型匹配技术、校正模型的方法和话者确认中一种先进的阈值方法．虽然在话者识别方面已取得了一些进展和成果，还有许多问题有待于解答、探索．

The introduces recent advances in speaker recognition technology. The paper discusses general topics and issues.The second part is devoted to a discussion of more specific topics of recent interest that have led to interesting new approaches and techniques.They include VQ and ergodic-HMM-based text-independent recognition methods, a text-prompted recognition method, parameter/distance normalization and model adaptation techniques, and methods of updating models and a proiori thresholds in speaker verification.Although many recent advances and successes have been achieved in speaker recognition, there are still many problems for which good solutionsremain to be found. The last part of this paper describes 16 open questions about speaker recognition.
