中文简介:	本文提出了一种自动提取和评估发音变体的“稳定性”的方法（即，模型的充分性以适应这种变化），基于每个词典单词的多个发音和参考基础形式发音的知识。在语音识别中建模发音可变性的大多数方法基于发音图（包括所有发音变体）的推断（通过遍历HMM模型），通常接着是所得图的平滑（例如，贝叶斯）。
课程简介:	This paper presents an approach to automatically extract and evaluate the ``stability'' of pronunciation variants (i.e., adequacy of the model to accommodate this variability), based on multiple pronunciations of each lexicon words and the knowledge of a reference baseform pronunciation. Most approaches toward modelling pronunciation variability in speech recognition are based on the inference (through an ergodic HMM model) of a pronunciation graph (including all pronunciation variants), usually followed by a smoothing (e.g., Bayesian) of the resulting graph.
