Description:
*Introduction* 2006 NIST Speaker Recognition Evaluation Training Set was developed by LDC and NIST (National Institute of Standards and Technology). It contains 595 hours of conversational telephone speech in English, Arabic, Bengali, Chinese, Hindi, Korean, Russian, Thai and Urdu and associated English transcripts used as training data in the NIST-sponsored 2006 Speaker Recognition Evaluation (SRE). The ongoing series of SRE yearly evaluations conducted by NIST are intended to be of interest to researchers working on the general problem of text independent speaker recognition. To this end the evaluations are designed to be simple, to focus on core technology issues, to be fully supported and to be accessible to those wishing to participate. The task of the 2006 SRE evaluation was speaker detection, that is, to determine whether a specified speaker is speaking during a given segment of conversational telephone speech. The task was divided into 15 distinct and separate tests involving one of five training conditions and one of four test conditions. Further information about the test conditions and additional documentation is available in the 2006 SRE Evaluation Plan. *Data* The speech data in this release was collected by LDC as part of the Mixer project, in particular Mixer Phases 1, 2 and 3. The Mixer project supports 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 and in different communicative situations and/or in multiple languages. The data is mostly English speech, but includes some speech in Arabic, Bengali, Chinese, Hindi, Korean, Russian, Thai and Urdu. The telephone speech segments are multi-channel data collected simultaneously from a number of auxiliary microphones. The files are organized into three types: two-channel excerpts of approximately 10 seconds, two-channel conversations of approximately 5 minutes and summed-channel conversations also of approximately 5 minutes. The speech files are stored as 8-bit u-law speech signals in separate SPHERE files. In addition to the standard header fields, the SPHERE header for each file contains some auxiliary information that includes the language of the conversation and whether the data was recorded over a telephone line. English language transcripts in .ctm format were produced using an automatic speech recognition (ASR) system. *Samples* For an example of the data contained in this corpus, review this audio sample. *Updates* None at this time.
