With the advent of technology, the availability of linguistic data in digital format has been increasingly encouraged to facilitate its use not only in different areas of Linguistics but also in related areas, such as natural language processing. Inspired by a protocol for digitizing the NURC (‘Cultured Linguistic Urban Norm’) project collection — one of the most influential in Brazilian Linguistics —, this paper aims to present the textto-speech alignment process of the NURC-Sao Paulo Minimal ˜ Corpus. This subcorpus comprises 21 audio files and audioaligned multilevel transcripts according to linguistically motivated intonation units (≈18 hours, ≈155 k words), covering three text genres. The dataset — currently used to evaluate methods for processing the entire NURC-SP corpus — is publicly available on the Portulan Clarin repository [CC BY-NCND 4.0] (https://hdl.handle.net/21.11129/0000-000F-73CA-C).
