Each speaker was recorded under two of three driving environments (parked, city driving and highway driving) with recording conditions such as fan on/off and window up/down. Each speaker will be recorded 150 utterances and spontaneous utterances per environment and totally 300 utterances were recorded for each speaker.
Four high quality audio channels (C1: SHURE SM10A, C2: SENNHEISER ME104, F1: AKG Q400, F2: AKG Q400) and at least two popular cars in the country were used for the recording.
