摘要翻译：
本文提出了一种嗓音变形系统，用于喉切除术，即手术切除全部或部分喉或语音盒，特别是喉癌患者。实现语音变形的一种基本方法是提取源语音系数，然后将其转换为目标说话人的语音参数。在本文中，我们使用高斯混合模型(GMM)来映射从源到目的地的系数。然而，使用传统的/常规的基于GMM的映射方法会导致转换语音的过平滑问题。因此，我们提出了一种独特的基于GMM的语音变形和转换方法，克服了传统方法的过平滑效应。该方法采用声门波形分离和激励预测技术，不仅消除了过平滑现象，而且转换后的声道参数与目标相匹配。此外，由此获得的合成语音被发现具有足够高的质量。因此，基于一种独特的GMM方法提出了语音变形，并根据各种主观和客观评价参数对语音变形进行了批判性评价。此外，本文还介绍了一种应用于喉切除患者的语音变形，该方法部署了这一独特的方法。

英文摘要：
This paper proposes a voice morphing system for people suffering from Laryngectomy, which is the surgical removal of all or part of the larynx or the voice box, particularly performed in cases of laryngeal cancer. A primitive method of achieving voice morphing is by extracting the source's vocal coefficients and then converting them into the target speaker's vocal parameters. In this paper, we deploy Gaussian Mixture Models (GMM) for mapping the coefficients from source to destination. However, the use of the traditional/conventional GMM-based mapping approach results in the problem of over-smoothening of the converted voice. Thus, we hereby propose a unique method to perform efficient voice morphing and conversion based on GMM,which overcomes the traditional-method effects of over-smoothening. It uses a technique of glottal waveform separation and prediction of excitations and hence the result shows that not only over-smoothening is eliminated but also the transformed vocal tract parameters match with the target. Moreover, the synthesized speech thus obtained is found to be of a sufficiently high quality. Thus, voice morphing based on a unique GMM approach has been proposed and also critically evaluated based on various subjective and objective evaluation parameters. Further, an application of voice morphing for Laryngectomees which deploys this unique approach has been recommended by this paper.
