摘要： Methods and apparatus for performing speaker recognition comprise processing a video signal associated with an arbitrary content video source and processing an audio signal associated with the video signal. Then, an identification and/or verification decision is made based on the processed audio signal and the processed video signal. Various decision making embodiments may be employed including, but not limited to, a score combination approach, a feature combination approach, and a re-scoring approach. In another aspect of the invention, a method of verifying a speech utterance comprises processing a video signal associated with a video source and processing an audio signal associated with the video signal. Then, the processed audio signal is compared with the processed video signal to determine a level of correlation between the signals. This is referred to as unsupervised utterance verification. In a supervised utterance verification embodiment, the processed video signal is compared with a script representing an audio signal associated with the video signal to determine a level of correlation between the signals.

摘要： Methods and apparatus for automatically deriving multiple phonetic baseforms of a word from a speech utterance of this word are provided in accordance with the present invention. In one embodiment, a method of automatically generating two or more phonetic baseforms from a spoken utterance representing a word includes the steps of: transforming the spoken utterance into a stream of acoustic observations; generating two or more strings of subphone units, wherein each string of subphone units represents a string of subphone units substantially maximizing a log-likelihood of the stream of acoustic observations, and wherein the log-likelihood is computed as a weighted sum of a transition score associated with a transition model and of an acoustic score associated with an acoustic model; and converting the two or more strings of subphone units into two or more phonetic baseforms.
摘要翻译：根据本发明提供了从该词的语音发音自动导出单词的多个语音基本形式的方法和装置。在一个实施例中，从表示单词的口语表达自动生成两个或多个语音基本形式的方法包括以下步骤：将口语发音转换成声学观察流; 产生两个或更多个子电话单元串，其中每个子电话单元串表示基本上最大化声学观测流的对数似然性的子电话单元串，并且其中对数似然性被计算为转换分数的加权和与过渡模型和与声学模型相关联的声学评分相关联; 并将两个或更多个子电话单元串转换成两个或更多个语音基础形式。
