title: Speech intelligibility index transfer functions and speech spectra for two Swedish speech recognition tests.
abstract: Speech spectra and Speech Intelligibility Index (SII) transfer functions are presented for the Swedish PB word material (SPB) and for a Swedish sentence material known as Hagerman's Sentences (HS). The transfer function were derived from the normative recognition scores in noise previously obtained from normal-hearing subjects. The transfer function for HS is very similar to a transfer function for familiar English sentences. The function for SPB is more like functions of other monosyllabic word test materials. The slope of the HS transfer function is twice as steep as the slope of the SPB function. The long-term rms spectra of the speech materials and their associated noise signals are presented and recommended to facilitate accurate SII calculations with these speech tests.
