Using similar recording and analysis techniques, the long-term average speech spectra of English and Mandarin were compared in order to identify difference that might influence hearing-aid fitting strategies. Despite the well-documented pitch contour differences between English and Mandarin, no significant difference was found in the long-term average spectral analysis. Implications for hearing-aid prescription are discussed.
