ORAL2008 is another spoken corpus available within the framework of the Czech National Corpus project. Its aim is appropriate representation of authentic spoken language. The corpus is built from material recorded in the whole of Bohemia in 2002–2007 using the same repository of recordings and their transcriptions as its predecessor, corpus ORAL2006. Individual transcriptions already included into ORAL2006 are not be re-used in ORAL2008, so that there is no intersection between the two corpora. Moreover, ORAL2008 is fully balanced according to the main sociolinguistic categories of the participating speakers: gender – male (M) / female (Z), age – under 35 (I) / over 35 (V), education – elementary or secondary (B) / university (A), and region of childhood residence (according to Bělič's division) – Central Bohemia / Northeast Bohemia / Southwest Bohemia / Czech borderland (these four regions are marginally supplemented also by Bohemian-Moravian transient region).

ORAL2008 is compiled from transcriptions of 297 recordings. All of the recordings were made in informal situations, which means the speakers knew each other and had friendly relationships. The total length of recordings is 6 883 minutes, that is almost 115 hours, and they contain a total of 1 000 097 words uttered by 995 speakers.

The recordings were made and the transcriptions carried out by students of Prague and regional universities, as well as other collaborators of the ICNC.
