A transcription corpus of daily conversations between elderly women who have never met each other before, with the aim of investigating ways to support elderly people in establishing new friendships. No particular theme for the conversation was specified.

  1. First-encounter conversation in real environment

    Eight healthy women over 70 years old were divided into two groups, and 12 conversations were recorded in pairs within each group. Each conversation takes about 10 minutes. (Distribution data is 9 conversations, excluding conversations in which one specific woman participates.)

  2. First-encounter conversation in remote environment

    The recordings were made using the video conferencing system Zoom with 8 women who were different from 1. After the first recordings, second recordings were also made two weeks later. Each conversation takes about 10 minutes.

This corpus consists of time-mapped texts for commercial audiobooks.

The total of 74 audiobooks (24 novels) were selected from a large number of commercial ones for speech synthesis research.
