This study deals with the distinction of the fricative noises of the spanish fricatives /th/ and /f/. Previous studies revealed that fricative noises of both phonemes are perceptually similar, auditory identification being significantly dependent on contextual effects: /f/ in the /u/ context is well identified (about 85% correct identification rate), while in the /e/ context identification is much lower (about 60%). Identification of /th/ is low for every vocalic context (about 60%). These effects were identical for both Hypo and Hyper forms of speech. The objective of this paper is to determine which acoustic properties of /f/ in the /u/ context make it a well defined phoneme for the two different forms of speech. We conclude that the cues for the identification of the isolated fricative noise of /f/ seem to be in the low frequency region of the spectrum.
