摘要:

本文提出了一种新的基于多锥度修正群时延函数的语音信号表示方法。一组音素为基础的实验,它表明,所提出的方法表现更好,现有的多锥度幅度(MT-MAG)估计技术,在方差和MSE方面,无论是在谱域和倒谱域。特别是,MT-MOGDF的性能被认为是最好的汤姆逊锥度。此外,MT-MOGDF技术的实用性是突出的说话人识别实验设置,其中获得的下一个最好的技术相比,约$20\%$的改进。此外,所提出的技术的计算要求是相当的MT-MAG。所提出的功能可以用于许多语音相关的应用程序,特别是,它是最适合那些需要说话人和语音信息。

英文摘要:

In this paper, a novel multitaper modified group delay function-based representation for speech signals is proposed. With a set of phoneme-based experiments, it is shown that the proposed method performs better that an existing multitaper magnitude (MT-MAG) estimation technique, in terms of variance and MSE, both in spectral- and cepstral-domains. In particular, the performance of MT-MOGDF is found to be the best with the Thomson tapers. Additionally, the utility of the MT-MOGDF technique is highlighted in a speaker recognition experimental setup, where an improvement of around $20\%$ compared to the next-best technique is obtained. Moreover, the computational requirements of the proposed technique is comparable to that of MT-MAG. The proposed feature can be used in for many speech-related applications; in particular, it is best suited among those that require information of speaker and speech.
