Data type: sound.

Applications: speaker identification.

LDC number: LDC2017S06.

Data: The speech recordings in this release were collected in 2009 and 2010 by LDC at its Human Subjects Collection facility in Philadelphia. This collection was part of the Mixer 6 project, which was designed to support the development of robust speaker recognition technology by providing carefully collected and audited speech from a large pool of speakers recorded simultaneously across numerous microphones. The telephone speech segments include two-channel excerpts of approximately 10 seconds and 5 minutes. There are also summed-channel excerpts in the range of 5 minutes. The microphone excerpts are 3-15 minutes in duration. As in prior evaluations, intervals of silence were not removed. The data included in this release is 8 bit ulaw with a sample rate of 8000. In addition to evaluation data, this package also consists of answer keys, trial and train files, development data and evaluation documentation.
