Document Summary
L in 22 8 l e c t u r e 8. Our ears are sensitive to different frequencies, but are more sensitive to lower frequencies, which is why most speech sounds have acoustic features at lower frequencies (sibilant fricatives are therefore an exception) We need both high and low frequencies. Genetically, these people are predisposed to developing ear disease (in particular otitis media) Arabic sibilants arabic has three /s/ or esh sounds (i. e. voiceless fricative sibilants: the pharyngealized /s/ creates a vowel that is lower and further back. Mandarin chinese three voiceless sibilants as well: /s/, / / and / : they all have high intensity noise, but the distribution of the noise is different . /s/ higher energy at higher frequencies, like in english. / / energy is at slightly lower frequencies compared to /s/ Rhotics any r -like sounds (usually written out as well as r : different types: taps, trills, alveolar, retroflex, and uvular.
