New publications:

(1) Multi-Language Conversational Telephone Speech 2011 -- South Asian was developed by LDC and is comprised of approximately 118 hours of telephone speech in five distinct language varieties of South Asia (i.e. the Indian sub-continent): Bengali, Hindi, Punjabi, Tamil and Urdu. The data were collected primarily to support research and technology evaluation in automatic language identification, and portions of these telephone calls were used in the NIST 2011 Language Recognition Evaluation (LRE). LRE 2011 focused on language pair discrimination for 24 languages/dialects, some which could be considered mutually intelligible or closely related.

Participants were recruited by native speakers who contacted acquaintances in their social network. Those native speakers made one call, up to 15 minutes, to each acquaintance. The data was collected using LDC's telephone collection infrastructure, comprised of three computer telephony systems. Human auditors labeled calls for callee gender, dialect type, and noise. Demographic information about the participants was not collected.

LDC has also released the following as part of the Multi-Language Conversation Telephone Speech 2011 series: Slavic Group (LDC2016S11)  and Turkish (LDC2017S09).
