Description:*Introduction* HKUST Mandarin Telephone Speech, Part 1 was developed by Hong Kong University of Science and Technology (HKUST). In 2004, HKUST was contracted to collect and transcribe 200 hours of Mandarin Chinese conversational telephone speech from Mandarin speakers in mainland China under the DARPA EARS framework. The first 50 hours of speech and transcripts were released in June 2004 to the EARS community for the RT-04 NIST evaluation. NIST partitioned the remaining 150 hours of collection into training, development and evaluation sets. This release contains the training and development sets with 873 and 24 calls, respectively. *Data Collection* Subject recruitment was done in several cities across mainland China. Most subjects did not previously know each other. To encourage more meaningful conversation, topics similar to those in Fisher English were designed. All calls were operator-assisted, namely, an operator would call two participants as scheduled to initiate a call. Subjects were asked about demographic questions before they were bridged for normal conversation. Their answers to the demographic questions were recorded on separate files. Subjects were allowed to talk up to 10 minutes. With a few exceptions, most calls are of the maximum length. Although subjects were allowed to make up to three calls, all subjects made just one call in this release with one exception, where PIN 10683 and PIN 10686 belong to a single individual. Each side of a call was recorded on a separate .wav file, sampled at 8-bits (a-law encoded), 8Khz. They were multiplexed later in sphere format with a-law encoding preserved. In the case where one side was shorter than the other, the shorter side was padded with silence. In the release, the file name of each recorded call is in the format of date_time_Apin_Bpin.sph and the corresponding transcript is in the same format with .txt extension. *Speaker demographics* Subjects were asked to provide several pieces of demographic information, including gender, age, native language/dialect, birthplace, education, occupation, phone type, etc. Given that Standard Mandarin is not the native dialect in many regions of China but is the official language of education and speakers may or may not have regional accents speaking Mandarin, it was decided that subjects birthplaces were divided into Mandarin-dominant and non-Mandarin-dominant regions and all calls were audited and classified into standard and accented types without further distinctions. Selected demographics - age, gender, birthplace, phone type and accent for each side of the call and the topic ID for the call - are provided as a tab-delimited, plain-text, tabular file. *Samples* To review an example of this corpus, please examine this wav or mp3 audio samples.
