Introduction

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.

Data

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)

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).

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.

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).
