The Wenzhou dialect is a Chinese dialect that is significantly distinct from Mandarin, the official language of China. It is among the most complex Chinese dialects and is nearly incomprehensible to people from regions such as Northern China, thereby creating substantial communication barriers. Therefore, the conversion between the Wenzhou dialect and Mandarin is essential to facilitate communication between Wenzhou dialect speakers and those from other Chinese regions. However, as a low-resource language, the Wenzhou dialect lacks publicly available datasets, and such conversion technologies have not been extensively researched. Thus, in this study, we create a parallel dataset containing Wenzhou dialect speech and the corresponding Mandarin text and build benchmark models for Wenzhou dialect speech-to-Mandarin text conversion. In particular, we fine-tune two self-supervised learning-based pretrained models, that is, TeleSpeech-ASR1.0 and Wav2Vec2-XLS-R, with our training dataset and report their performance on our test dataset as baselines for future research.

Large Language Models (LLMs) have demonstrated great potential for assisting developers in their daily development. However, most research focuses on generating correct code, how to use LLMs to generate personalized code has seldom been investigated. To bridge this gap, we proposed MPCoder (Multi-user Personalized Code Generator) to generate personalized code for multiple users. To better learn coding style features, we utilize explicit coding style residual learning to capture the syntax code style standards and implicit style learning to capture the semantic code style conventions. We train a multi-user style adapter to better differentiate the implicit feature representations of different users through contrastive learning, ultimately enabling personalized code generation for multiple users. We further propose a novel evaluation metric for estimating similarities between codes of different coding styles. The experimental results show the effectiveness of our approach for this novel task.
