The use of segment-based features and segmentation networks
in a segment-based speech recognizer complicates
the probabilistic modeling because it alters the sample space
of all possible segmentation paths and the feature observation
space. This paper describes a novel Baum-Welch training
algorithm for segment-based speech recognition which
addresses these issues by an innovative use of finite-state
transducers. This procedure has the desirable property of
not requiring initial seed models that were needed by the
Viterbi training procedure we have used previously. On the
PhoneBook telephone-based corpus of read, isolated words,
the Baum-Welch training algorithm obtained a relative error
reduction of 37% on the training set and a relative error
reduction of 5% on the test set, compared to Viterbi
trained models. When combined with a duration model,
and more flexible segmentation network, the Baum-Welch
trained models obtain an overall word error rate of 7.6%,
which is the best result we have seen published for the 8,000
word task.

基于段的语音识别中对基于段的特征和分段的网络的使用，会因为它改变了所有可能分段路径的样本空间和特征观察空间，而使得其盖然论建模变得复杂。这篇论文描述了一种新颖的Baum-Welch训练算法，它以对有限状态变换器的创造性地运用来处理基于段的语音识别中的这些问题。其过程相比于Viterbi训练过程有令人欣喜的优势，那就是它不需要最初的原始模型。以从电话号码簿上的文本得到的孤立词为数据，Baum-Welch训练算法相比于从Viterbi训练得到的模型，在训练模块减少了37%的相关误差，在识别模块减少了5%的相关误差。当由Baum-Welch训练算法得到的模型与一个持续时间的模型和更多复杂的分段网络相结合之后，它的总体的单词差错率为7.6%，这是我们目前看到的已发表的8000单词任务中结果最好的。
