In this paper, we propose a spoken term detection algorithm for simultaneous prediction and localization of in-vocabulary and out-of-vocabulary terms within an audio segment. The proposed algorithm infers whether a term was uttered within a given speech signal or not by predicting the word embeddings of various parts of the speech signal and comparing them to the word embedding of the desired term. The algorithm utilizes an existing embedding space for this task and does not need to train a task-specific embedding space. At inference the algorithm simultaneously predicts all possible locations of the target term and does not need dynamic programming for optimal search. We evaluate our system on several spoken term detection tasks on read speech corpora.

研究了零资源环境下的示例查询口语词检测问题。现有技术的方法主要依赖于基于动态时间规整(DTW)的模板匹配技术,该技术使用从深度神经网络(DNN)提取的音素后验或瓶颈特征。我们使用单语和多语言瓶颈功能,并表明多语言功能的表现越来越好,更多的训练语言。先前,已经示出了基于DTW的匹配可以被基于CNN的匹配替换,同时使用后验特征。在这里,我们表明,基于CNN的匹配优于基于DTW的匹配使用瓶颈功能以及。在这种情况下,我们的QbE-STD系统的特征提取和模式匹配阶段相互独立地进行优化。我们建议将这两个阶段整合到一个完全基于神经网络的端到端学习框架中,以同时实现这两个阶段的联合优化。在两个具有挑战性的多语言数据集上对所提出的方法进行了评估:Spoken Web Search 2013和Query by Example Search on Speech Task 2014,在每种情况下都有显着的改进。
