The WikiTongues speech corpus is a collection of conversational audio across 700+ languages.
It can be used for spoken language modelling or speech representation learning.
This dataset includes the raw unsegmented audio in a 16kHz single channel format.
Each clip is usually 2-10 minutes long, and contains one or more speakers conversing in their language(s).
Sometimes, a speaker may switch languages within a single clip.
The total dataset size is around 70 hours.
**The current version of the dataset does not include labels for the language(s) being spoken in each clip. This information will be included in an update in the near future**
This dataset was crawled from the [WikiTongues project](https://wikitongues.org/), which collected the original recordings.
We use this corpus to train [XEUS](https://huggingface.co/espnet/xeus), a multilingual speech encoder for 4000+ languages. For more details about the dataset and its usage, please refer to our [paper](https://wanchichen.github.io/pdf/xeus.pdf) or [project page](https://www.wavlab.org/activities/2024/xeus/).
