- Datatang 'application-validation multimodal corpus, phase 1' (应用验证多模态语料（一期）), one set, off-the-shelf brand and model 数据堂
The same central buyer that bought Lifewood speech data in 2024 (named only by an ID code, Shenzhen) bought a Datatang multimodal corpus. A winning bid for Datatang's own product (brand 数据堂, not custom), so a purchase of existing data; the notice does not state its size. Amount and supplier confirmed in a browser read of the notice on 21 Oct 2026; ccgp.gov.cn refuses scripted reads, so the quote sets out the notice's table cells in order.
The payer's own page, China Government Procurement Network (ccgp.gov.cn), winning-bid notice 22 Sep 2026: 应用验证多模态语料（一期）采购项目中标公告
