xSID-audio 0.2

xSID-audio consists of audio recordings for xSID, a multilingual dataset for slot and intent recognition. For more details and a data statement, see:

• Verena Blaschke, Miriam Winkler, and Barbara Plank. 2026. Standard-to-Dialect Transfer Trends Differ across Text and Speech: A Case Study on Intent and Topic Classification in German Dialects. In Proceedings of the 64th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers), pages 6807–6829, San Diego, California, United States. Association for Computational Linguistics.

Release 0.2 of xSID-audio contains audio recordings for the validation and test sets of the xSID 0.5 splits for German (de) and for Bavarian as spoken in rural Upper Bavaria (de-ba). xSID-audio consists of read speech. The audios for German and Bavarian are recorded by the same speaker. More details are in the data statement in the appendix of Blaschke, Winkler & Plank (2026).

Updates:

• v0.2: Updates to the metadata TSV files (no updates to the audio files):
  • A. This fixes a misalignment between the Bavarian sentence IDs on the one hand, and the German sentences & Bavarian audios on the other hand in the xSID test files. This part of the update corresponds exactly to how we used the data in the experiments for the ACL 2026 paper.
  • B. It also provides updated text versions of a few xSID sentences whose original translations deliberately included orthographical/grammatical errors (see Appendix F of van der Goot et al., 2021), which are fixed in the audio version to make the recordings more natural, or abbreviations which were expanded for the audio recordings (e.g., "AK" -> "Alaska", "Nov." -> "November"). The Text column contains the recorded version, Text_original the version as it appears in xSID.
• v0.1: Initial release.

Using and citing xSID-audio

We share the audio recordings for research on processing spoken language data, but do not permit their use in the context of speech synthesis or voice cloning.

If you use xSID-audio, please cite the publication in which we introduce the dataset:

Please also cite the publications associated with xSID listed at the bottom of this file (at least the publications for related to the German and Bavarian xSID data: van der Goot et al., 2021, and Winkler et al., 2024).

Folder structure and file types:

• The folders de and de-ba contain the recordings for the German and Bavarian data, respectively.
• They each contain a subfolder for the validation (valid) and test (test) splits.
• Each recording is a WAV file (recording rate: 48 kHZ, bit rate: 768 kBit/s).
• The TSV files in the top-level folder (xsid_{de,de-ba}_{valid,test}.tsv) contain the instance ID for each sentence, the text from xSID 0.7, the intent from xSID 0.7, and the corresponding audio path.
