Some type of sound normalizer to increase quiet whispers

The human voice provides a multitude of cues to person identity вЂ“ from only a short recording of a voice, listeners can discriminate between speakers, recognise them as familiar and identify them by their names (Kreiman & Sidtis, 2011). To do this, our theoretical and methodological frameworks need to be adjusted to explicitly include the study of within-person variability. In this paper, we propose that we need to extend the focus of voice-identity research to account for both вЂњtelling people togetherвЂќ as well as вЂњtelling people apart.вЂќ That is, we must account for whether, and to what extent, listeners can overcome within-person variability to obtain a stable percept of person identity from vocal cues. We argue that this obscures our understanding of voice-identity processing by controlling away an essential feature of vocal stimuli that may include diagnostic information. However, in most studies of voice-identity processing to date, the substantial within-person variability has been eliminated through the use of highly controlled stimuli, thus focussing on how we tell people apart. In order to successfully recognise someone from their voice, a listener needs to be able to generalize across these different vocal signals (вЂtelling people togetherвЂ™). Human voices are extremely variable: The same person can sound very different depending on whether they are speaking, laughing, shouting or whispering.
