Recent breakthroughs in NLP largely increased the presence of ASR systems in
our daily lives. However, for many low-resource languages, ASR models still
need to be improved due in part to the difficulty of acquiring pertinent data.
This project aims to help advance research in ASR models for Swiss German
dialects, by providing insights about the performance of state-of-the-art ASR
models on recently published Swiss German speech datasets. We propose a novel
loss that takes into account the semantic distance between the predicted and
the ground-truth labels. We outperform current state-of-the-art results by
fine-tuning OpenAI's Whisper model on Swiss-German datasets.

本研究旨在提高 ASR 模型在瑞士德语方言上的表现，通过提供对最新发布的瑞士德语语音数据集上现有现有 ASR 模型性能的深入了解。我们提出了一种考虑预测和真实标签之间语义距离的新型损失函数，通过对 Swiss-German 数据集上 OpenAI 的 Whisper 模型进行微调，取得了优于当前最新研究成果的结果。

Spaiche: Extending State-of-the-Art ASR Models to Swiss German Dialects

The goal of this work is to design a machine translation (MT) system for a
low-resource family of dialects, collectively known as Swiss German, which are
widely spoken in Switzerland but seldom written. We collected a significant
number of parallel written resources to start with, up to a total of about 60k
words. Moreover, we identified several other promising data sources for Swiss
German. Then, we designed and compared three strategies for normalizing Swiss
German input in order to address the regional diversity. We found that
character-based neural MT was the best solution for text normalization. In
combination with phrase-based statistical MT, our solution reached 36% BLEU
score when translating from the Bernese dialect. This value, however, decreases
as the testing data becomes more remote from the training one, geographically
and topically. These resources and normalization techniques are a first step
towards full MT of Swiss German dialects.

设计了一种机器翻译系统，使用字符级神经网络翻译文本，并结合基于短语的统计翻译，实现了对伯尔尼方言的 36% BLEU 得分的翻译。这些资源和规范化技术是通向瑞士德语方言全面机器翻译的第一步。
