Improving Code-Switching Language Modeling with Artificially Generated Texts Using Cycle-Consistent Adversarial Networks
Chia-Yu Li, Ngoc Thang Vu · 2020
This paper presents our latest effort on improving Codeswitching language models that suffer from data scarcity.We investigate methods to augment Code-switching training text data by artificially generating them.Concretely, we propose a cycle-consistent adversarial networks based framework to transfer monolingual text into Code-switching text, considering Code-switching as a speaking style.Our experimental results on the SEAME corpus show that utilizing artificially generated Code-switching text data improves consistently the language model as well as the automatic speech recognition performance.
