一种开放词汇表语音驱动的文本检索方法

A Method for Open-Vocabulary Speech-Driven Text Retrieval

Atsushi Fujii, Katunobu Itou, Tetsuya Ishikawa

摘要:

虽然最近的检索技术不限制索引词的数量,但词汇表外(OOV)词在语音识别中至关重要。针对语音查询的信息检索,我们填补了语音识别和文本检索在词汇量方面的空白。给定一个口头查询,我们生成一个转录和检测OOV的话,通过语音识别。然后,我们将检测到的OOV单词对应到目标集合中索引的术语以完成转录,并在集合中搜索与完成的转录相关的文档。我们通过实验证明了我们的方法的有效性。

英文摘要:

While recent retrieval techniques do not limit the number of index terms, out-of-vocabulary (OOV) words are crucial in speech recognition. Aiming at retrieving information with spoken queries, we fill the gap between speech recognition and text retrieval in terms of the vocabulary size. Given a spoken query, we generate a transcription and detect OOV words through speech recognition. We then correspond detected OOV words to terms indexed in a target collection to complete the transcription, and search the collection for documents relevant to the completed transcription. We show the effectiveness of our method by way of experiments.
