This preliminary study was designed to ascertain the relative intelligibility of the twenty-six individual spoken alphabet letters when presented to normal listeners over a 45-db range of levels. The gain function for the pooled results of 26 letters spoken by three experienced speakers to 18 listeners has a sigmoidal shape. The 15-db increase in presentation level from 10 to 25 db yields a 65% increase in correct identification for all letters. The average slope of the pooled curve for all letters between 20 and 80% was 4.34% per db. The curves appear to be similar to those of the more difficult stimuli such as the monosyllable PB lists and unselected disyllabic lists. Percentages of correct identifications for each letter at each presentation level are also presented. [ABSTRACT FROM AUTHOR] |
