Speech perception -- Testing, Speech synthesis
The purpose of this study was to develop two tape-recorded synthetic speech discrimination test tapes and assess their intelligibility in order to determine whether or not synthetic speech was intelligible and if it would prove useful in speech discrimination testing. Four scramblings of the second MU-6 monosyllable word list were generated by the ECHO l C speech synthesizer using two methods of generating synthetic speech called TEXTALKER and SPEAKEASY. These stimuli were presented in one ear to forty normal-hearing adult subjects, 36 females and 4 males, at 60 dB HL under headphone&. Each subject listened to two different scramblings of the 50 monosyllable word list, one scrambling generated by TEXTALKER and the other scrambling generated by SPEAKEASY. The order in which the TEXTALKER and SPEAKEASY mode of presentation occurred as well as which ear to test per subject was randomly determined.
