 ### ORTOFON
-The **ORTOFON corpus** captures spontaneous spoken language used in informal situations between speakers who know each other. It follows the ORAL series of informal spoken Czech corpora in its data collection design. The recordings are transcribed in two tiers - orthographic and phonetic. Together with the DIALEKT corpus, these are the first two spoken Czech corpora to have multi-tier transcription. Similar to the ORAL2013 corpus, speakers come from all over the Czech Republic and selected sociological information is collected about them.
