ALC contains recordings of German speakers that are either intoxicated or sober. The type of speech ranges from read single digits to full conversation style. Recordings were done during drinking test where speakers drank beer or wine to reach a self-chosen level of alcoholic intoxication. The actual level of intoxication was measured by breath alcohol and blood samples taken immediately before the speech recording. Recordings were performed in two standing automobiles to ensure a constant acoustic environment across the different recording locations; both, the intoxicated and sober condition recording were done in the same car and supervised by the same investigator (dialogue partner). In the intoxicated state 30 items were sampled from each speaker (set A), while in the sober state 60 items were recorded (set NA; set A being a subset of set NA).
