摘要:

语言识别(LID)在许多语音处理应用中具有相关性。对于语码转换语音的自动识别,传统的方法通常采用LID系统来检测话语中存在的语言。在现有的工作中,语码转换语音的LID涉及单独的底层语言的建模。在这项工作中,我们提出了一个联合建模为基础的LID系统的代码切换语音。为了实现同样的目标,已经探索了基于注意力的端到端(E2 E)网络。为了开发和评估所提出的方法,最近创建的印地语-英语代码转换语料库已被使用。为了对比的目的,LID系统采用连接主义的时间分类为基础的E2 E网络也被开发。在比较两种LID系统时,注意力基于方法导致更好的LID准确性。通过绘制E2 E网络的注意力权重,证明了该方法对语码转换边界的有效定位。

英文摘要:

Language identification (LID) has relevance in many speech processing applications. For the automatic recognition of code-switching speech, the conventional approaches often employ an LID system for detecting the languages present within an utterance. In the existing works, the LID on code-switching speech involves modelling of the underlying languages separately. In this work, we propose a joint modelling based LID system for code-switching speech. To achieve the same, an attention-based end-to-end (E2E) network has been explored. For the development and evaluation of the proposed approach, a recently created Hindi-English code-switching corpus has been used. For the contrast purpose, an LID system employing the connectionist temporal classification-based E2E network is also developed. On comparing both the LID systems, the attention based approach is noted to result in better LID accuracy. The effective location of code-switching boundaries within the utterance by the proposed approach has been demonstrated by plotting the attention weights of E2E network.
