Description:*Introduction* Multi-Language Conversational Telephone Speech 2014 - Spanish & Portuguese was developed by the Linguistic Data Consortium (LDC) and is comprised of approximately 123.8 hours of telephone speech in Spanish and Portuguese. The data was collected primarily to support research and technology evaluation in automatic language identification; portions of these recordings were used in the NIST 2015 and 2017 language recognition evaluations. The collection focused on language pair discrimination for 20 languages/dialects, some of which could be considered mutually intelligible or closely related. *Data* This corpus contains 569 recordings covering Brazilian Portuguese, Caribbean Spanish, European Spanish and Latin American Spanish. Participants were recruited by native speakers who contacted acquaintances in their social networks. Those native speakers made one call, up to 8 minutes, to each acquaintance. The data was collected using LDC's telephone collection infrastructure. Human auditors labeled calls for language, quality, callee gender, dialect type and noise. All audio data is presented in FLAC-compressed MS-WAV (RIFF) file format (*.flac); when uncompressed, each file is 2 channels, recorded at 8000 samples/second with samples stored as 16-bit signed integers, representing a lossless conversion from the original mu-law sample data as captured digitally from the public telephone network. The following table summarizes the total number of calls, total number of hours of recorded audio, and the total size of compressed data: Group Lanugage Calls Hours Size (GB) Portuguese Portuguese - Brazillian 20 4.78 0.26 Spanish Spanish - Carribean 105 23.69 1.16 Spanish Spanish - Europe 205 44.20 0.26 Spanish Spanish - Latin America 239 51.13 2.51 *Samples* Please view these samples: * Brazilian Portuguese (FLAC) * Caribbean Spanish (FLAC) * European Spanish (FLAC) * Latin American Spanish (FLAC) *Updates* No updates at this time.
