Tactical Speaker Identification Speech Corpus (TSID)

<h3>Introduction</h3> <p>The Tactical Speaker Identification Corpus (TSID), which was collected by Douglas Reynolds and Gerald C. O'Leary of MIT Lincoln Labs, contains recordings of 35 speakers (four female, 31 male), using a variety of different radio transmitters and receivers. </p><h3>Data</h3> The recording sessions were conducted by assembling the speakers into seven groups of five, then having each speaker perform the following tasks: - read a list of TIMIT sentences - read a list of digit strings - give directions for traveling from one point to another using a map (unscripted map task) <p>Each speaker performed this set of tasks on each of three transmitters (xmtr1-3), and the utterances were recorded simlutaneously on DAT recorders attached to each of six receivers (rcvr1-6), which were located at some distance (well out of ear-shot) from the transmitter. Recordings were also made at the same time on a DAT recorder near the speaker using a head-mounted microphone to provide a reference wide-band recording of the speech (refwb). </p><p>As a result, the corpus is organized along four dimensions: speaker, transmitter, receiver, and speaking task; this organization can be viewed as a four-dimensional matrix, with 35x3x7x3 cells. Due to some occasional mishaps and malfunctions during the collection, some cells in this matrix are either empty or only partially full. </p><p>In addition to the tasks listed above, three pairs of speakers also participated in a two-way map task using xmtr3; in this case, one of the speakers in the task gives directions to the other for tracing a route on a map, and both speakers are recorded on a single audio channel at each of the receivers (except for the "refwb" recording: the two speakers were separated by some distance, using radio communication to perform the task, and only one of them used a head-mounted microphone and local DAT recorder for wide-band recording). </p><h3>Updates</h3> There are no updates at this time. </br>
