- This database contains two non-contemporaneous recordings of each of 68 female speakers of Standard Chinese (a.k.a. Mandarin and Putonghua).
- 60 of the speakers are from north eastern China, and 8 are from southern China.
- Each speaker was recorded in three speaking styles:
- casual telephone conversation (cnv)
- information exchange task over the telephone (fax)
- pseudo-police-style interview (int)
- Recordings were made at China Criminal Police University in Shenyang, China, under the supervision of Cuiling Zhang.
- Data collection was financially supported by an International Association for Forensic Phonetics and Acoustics (IAFPA) Research Grant:
- Zhang, C., & Morrison, G.S. (2009). Forensic comparison of Chinese female voices. Application for an International Association for Forensic Phonetics and Acoustics Research Grant.
