摘要:

在本文中,我们提出了一个口语术语检测算法,同时预测和定位的词汇表内和词汇表外的音频段内的条款。该算法通过预测语音信号的各个部分的词嵌入并将其与所需术语的词嵌入进行比较来推断术语是否在给定的语音信号内发出。该算法利用一个现有的嵌入空间的任务,并不需要训练一个特定于任务的嵌入空间。在推理时,该算法同时预测目标项的所有可能位置,并且不需要动态规划进行最优搜索。我们评估我们的系统上读语音语料库的几个口语术语检测任务。

英文摘要:

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.
