AI总结:

本文提出Faetar自动语音识别基准,一个极度低资源的Franco-Provençal语变体语料库,含5小时标注和20小时无标签语音,并报告了使用无标签数据继续预训练的多语言基础模型达到30.4%最佳音素错误率的基线结果。

摘要:

我们推出了Faetar自动语音识别基准(Faetar Automatic Speech Recognition Benchmark),这是一个旨在挑战当前低资源语音识别方法极限的基准语料库。Faetar是一种主要在意大利使用的Franco-Provençal语变体,没有标准正字法,除基准中包含的资源外,几乎没有现存文本或语音资源,且与其他形式的Franco-Provençal语差异显著。该语料库来源于实地录音,其中大部分含有噪声,仅有5小时录音配有匹配的转写文本,且强制对齐质量参差不齐。语料库还包含额外20小时的无标签语音。我们报告了最先进的多语言语音基础模型的基线结果,最佳音素错误率为30.4%,该结果是通过使用无标签数据集对基础模型进行持续预训练的流程获得的。

英文摘要:

We introduce the Faetar Automatic Speech Recognition Benchmark, a benchmark corpus designed to push the limits of current approaches to low-resource speech recognition. Faetar, a Franco-Provençal variety spoken primarily in Italy, has no standard orthography, has virtually no existing textual or speech resources other than what is included in the benchmark, and is quite different from other forms of Franco-Provençal. The corpus comes from field recordings, most of which are noisy, for which only 5 hrs have matching transcriptions, and for which forced alignment is of variable quality. The corpus contains an additional 20 hrs of unlabelled speech. We report baseline results from state-of-the-art multilingual speech foundation models with a best phone error rate of 30.4%, using a pipeline that continues pre-training on the foundation model using the unlabelled set.
