This was my first research project as a graduate student at Indiana University where I started out in David Pisoni’s speech perception laboratory. The basic question we addressed was whether details of the voice of a speaker were encoded in long-term memory representations for spoken words. Many leading theories at the time suggested that voice attributes were normalized out during speech recognition, which meant that details of the voice of the speaker would be absent from any long-term memory representations of spoken words. We instead found evidence that words are better recognized when they are spoken by the same speaker, which meant that long-term memory representations do contain perceptual details. This empirical work was an important foundation for my later research examining how perceptual details are encoded in visual memories for objects that support recognition, categorization, and identification.
