# Can I get a free sample before purchasing?

Yes — many datasets in the catalog offer free samples so you can validate format, quality, and fit before committing to a purchase.

Sampling is the fastest way to de-risk a data purchase. For speech corpora, samples typically include audio recordings alongside their aligned transcripts, so you can check signal quality and annotation precision directly. To request a sample, browse the catalog at datamall.thordata.com, filter by modality, and submit a request for the datasets you are evaluating. If the catalog does not contain exactly what you need, you can submit a custom requirement and discuss a proof-of-concept batch with the consultant instead.
