Little is known about intraspeaker changes in voice across changing speaking situations in everyday life. In this study, we examined acoustic variations between and within 5 talkers and their effect on the likelihood that voice samples would not be identified as coming from the same talker. Talkers were drawn from a large database recorded to capture everyday variations in vocal characteristics...

Previous research employing a real-time auditory perturbation paradigm has shown that talkers monitor their own speech attributes such as fundamental frequency, vowel intensity, vowel formants, and fricative noise as part of speech motor control. In the case of vowel formants or fricative noise, what was manipulated is spectral information about the filter function of the vocal tract. However, ...

Speech perception and talker identification are intertwined. Speech from a single talker is recognized more efficiently than speech from multiple talkers; likewise, in the “language familiarity effect”, talker identification is more accurate in one's native language than a foreign one. Models of speech perception implicate episodic memory to explain effects of phonetic variability. We investiga...

A visual fixation study tested whether 7-month-olds can discriminate between different talkers. The infants were first habituated to talkers producing sentences in either a familiar or unfamiliar language, then heard test sentences from previously unheard speakers, either in the language used for habituation, or in another language. When the language at test mismatched that in habituation, infa...

Morton, Marcus, and Frankish (1976) report that listeners hear acoustically isochronous digit sequences as anisochronous. Moreover, given a chance to adjust intervals in the sequences until they are perceptually isochronous, the listeners introduce systematic deviations from isochrony. The present series of studies investigates these phenomena further. They indicate that when asked to produce i...

The Navajo Code Talkers, who faithfully transmitted messages in an indecipherable code to support U.S. military efforts from 1942 to 1945, are widely credited with the achievement of numerous victories in the Pacific theater during World War II (WWII), among them the capture of Iwo Jima by the Marine Corps in 1945.1-3 Originally a highly classified military secret, the Code Talkers’ work was co...
