摘要： The invention refers to a method for comparing voice utterances, the method comprising the steps: extracting a plurality of features (201) from a first voice utterance of a given text sample and extracting a plurality of features (201) from a second voice utterance of said given text sample, wherein each feature is extracted as a function of time, and wherein each feature of the second voice utterance corresponds to a feature of the first voice utterance; applying dynamic time warping (202) to one or more time dependent characteristics of the first and/or second voice utterance e.g. by minimizing one or more distance measures, wherein a distance measure is a measure for the difference of a time dependent characteristic of the first voice utterance and a corresponding time dependent characteristic of the second voice utterance, and wherein a time dependent characteristic of a voice utterance is a time dependent characteristic of either a single feature or a combination of two or more features; calculating a total distance measure (203), wherein the total distance measure is a measure for the difference between the first voice utterance of the given text sample and the second voice utterance of said given text sample, wherein the total distance measure is calculated based on one or more pairs of said time dependent characteristic, and wherein a pair of time dependent characteristic is calculate total composed of a time dependent characteristic of the first or second voice utterance and of a dynamically time warped (202) time dependent characteristic of the respectively second or first voice utterance, or wherein a pair of time dependent characteristic is composed of a dynamically time warped (202) time dependent characteristic of the first voice utterance and of a dynamically time warped (202) time dependent characteristic of the second voice utterance.
摘要翻译：本发明涉及一种用于比较语音话语的方法，所述方法包括以下步骤：从给定文本样本的第一语音发音中提取多个特征（201），并从第二话音语音提取多个特征（201）所述给定文本样本，其中每个特征被提取为时间的函数，并且其中所述第二语音话语的每个特征对应于所述第一语音话语的特征; 将动态时间扭曲（202）应用于第一和/或第二语音话语的一个或多个时间依赖特性，例如。通过最小化一个或多个距离度量，其中距离度量是用于第一语音发音的时间相关特性与第二语音发音的对应时间相关特性的差的度量，并且其中语音话语的时间相关特性是单个特征或两个或更多个特征的组合的时间依赖特性; 计算总距离测量（203），其中所述总距离测量是用于所述给定文本样本的所述第一语音发音与所述给定文本样本的所述第二语音发声之间的差的度量，其中所述总距离测量基于一对或多对所述时间依赖特性，并且其中一对时间依赖特性是计算由第一或第二语音话语的时间依赖特性组成的总和以及分别第二或第二语音话语的动态时间扭曲（202）时间依赖特性或第一语音话语，或者其中一对时间依赖特性由第一语音话语的动态时间扭曲（202）时间依赖特性和第二语音话语的动态时间扭曲（202）时间依赖特性组成。
