This file contains documentation on the Russian through Switched Telephone Network (RuSTeN), Linguistic Data Consortium (LDC) catalog number LDC2006S34 and ISBN 1-58563-388-7.
This corpus was developed as part of ?Trawl? (Automatic Voice Identification System in Telephone Channel). The purpose of the project was to develop software for automatic identification of speakers based on voice samples acquired through telephone channels. The training of the system was performed with the telephone speech corpus RuSTeN.
The RuSTeN (Russian through Switched Telephone Network) database was recorded between March 2001 and February 2003 by Speech Technology Center using the "forget-me-not" professional telephone recording and archiving software package developed by STC. The files were recorded with sample frequency 11025 Hz, one-channel, 16-bit linear.
Each of the speakers made at least five calls from different locations and/or telephone sets. Most of the calls were made from home or an office environment with uncontrolled noise level. Additionally, one call per speaker was made from a public telephone (with either street or metro station noise in the background). The recordings are spontaneous (sometimes guided by the near-end speaker) conversations between the caller and the speech database collector on various subjects (the weather, the caller's biography, hobbies, etc.) and include approximately 150 seconds of the far-end and at least five seconds of the near-end speaker. Besides, each time the caller was asked to utter the usual digits set (0-9) and the words "yes" and "no."
The time interval between two successive sessions is at least two days. The database contains 125 speakers (far-end), 58 male and 67 female. Each far-end speaker is represented by at least five speech files. The sound files are in the wav-format. The speech filenames contain the following information: FFF (far-end speaker number) and SS (session number).
