Phone Conversations in Japanese

These phone conversations were recorded using the phone conversation module on Summa Linguae’s Robson app. The data set includes 500 hours of time-stamped and transcribed unscripted speech data (i.e. natural conversation) between two speakers. Each speech segment is at maximum 15 seconds in length. Each conversation is at least 15 minutes long. Calls with more than two speakers have been removed from the corpus. The transcription is done in time-stamped segments of 15 seconds in length at maximum. Each segment indicates the speaker, the start and the end of the segment, and additional information on the segment.
