MuPe Life Stories Dataset
A new publicly available dataset consisting of 289 life story interviews (365 hours), featuring a broad range of speakers varying in age, education, and regional accents.
Metadata:
- audio_id: Sequential id for the interview;
- audio_name: Unique code for the interview;
- file_path: Wav audio file path;
- speaker_type: R is the interviewee, P/1 is interviewer 1, P/2 is interviewer 2 and so on;
- speaker_code: Unique code for the speaker;
- speaker_gender: Gender of the speaker;
- education: Education level of the interviewee, filled only when speaker_type = 'R';
- birth_state: Birth state (region) of the interviewee, filled only when speaker_type = 'R';
- birth_country: Birth country of the speaker;
- age: Age of the interviewee, calculated with recording_year minus year of birth, filled only when speaker_type = 'R';
- recording_year: The year when the audio was recorded;
- audio_quality: Can be high or low;
- start_time: The start time in the original complete audio file;
- end_time: The end time in the original complete audio file;
- duration: The duration of the segment;
- normalized_text: Text normalized in lowercase and without punctuation marks;
- original_text: Text before normalization.
- racial_category: Racial category may be Black, White, Pardo (Mixed) and Asian. Few interviews have this information.
