A speaker recognizability test for communications systems
Panos E. Papamichalis, George R. Doddington · The Journal of the Acoustical Society of America · 1983
A Speaker Recognizability Test (SRT) has been designed which tries to establish how well a given communications system preserves a speaker's identity. Contrary to previous efforts, no attempt is made to identify the cues used by listeners for speaker recognition. Instead, listeners are asked directly to identify a speaker who says an utterance. The test is constructed as follows: Several sentences are collected from five male and five female speakers. One sentence from each speaker is used as reference. The listening team consists of ten listeners. Each listener is presented 20 different sentences and is asked to identify the speaker of each one of them by comparing it with the ten reference sentences. Among the issues considered in the design of the test is the choice of speakers, the use of reference sentences from the same or different sessions of data collection, and the use of processed or unprocessed speech for reference.
