A third of the transcripts (35 %, 145 hours) has been created very carefully using a systematic transcription approach and manual quality cross-checks, resulting in an orthographic basic transcription (Wendelstein, 2016).
the majority of the transcripts (65 %, 236 hours) does not follow the criteria of linguistic transcripts, was created without any postchecks and includes hardly any transcribed vocables (hesitations, back-channeling, disfluencies).
