Does vowel recognition relate to pitch? Acoustics Virtually Everywhere (AVE), Maurer et al., 2020
	> Close	Background The vowel spectrum of natural sounds relates to fundamental frequency (fo) Sound series for illustration   Series of sounds produced by a woman with extensive variation of fundamental frequency (fo) in the range of 131–784 Hz (levels given according to musical C-major scale). The sounds for the closed and mid-closed vowels illustrate a pronounced relation of the lower vowel spectrum and fo. The sounds for the mid-open and open vowels illustrate inconsistent or weak or absent relation of the lower vowel spectrum and fo and point at the nonuniform character of the relation. > Series 1: Sounds of /i/ > Series 2: Sounds of /y/ > Series 3: Sounds of /e/ > Series 4: Sounds of /ø/ > Series 5: Sounds of /ɛ/ > Series 6: Sounds of /a/ > Series 7: Sounds of /o/ > Series 8: Sounds of /u/ The series were previously shown in Maurer et al (2019).
