A follow-up question: is anyone aware of research on OE in speech perception? The only study I can find is:
Peter, B., Larkin, T., & Stoel-Gammon, C. (2009). Octave-shifted pitch matching in nonword imitations: The effects of lexical stress and speech sound disorders. The Journal of the Acoustical Society of America, 126(4), 1663-1666.
