Use Of Synthetic Speech In Tests Of Speech Discrimination, Jane S. Gordon
Use Of Synthetic Speech In Tests Of Speech Discrimination, Jane S. Gordon
Dissertations and Theses
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 …
One-Third Octave Band Augmented Speech Discrimination Testing For Cochlear Impaired Listeners, Dianne Heath
One-Third Octave Band Augmented Speech Discrimination Testing For Cochlear Impaired Listeners, Dianne Heath
Dissertations and Theses
The purpose of this study was to investigate the effects of a 500 Hz and 3,150 Hz one-third octave band augmentation on the speech discrimination ability of listeners with cochlear hearing impairments. The results were analyzed both within the experimental group of subjects included in the present study and in comparison with data collected on a control group of normal hearing subjects reported earlier.
One-Third Octave Band Augmented Speech Discrimination Testing For Normal Hearing Listeners, Nancy Marie Bowen
One-Third Octave Band Augmented Speech Discrimination Testing For Normal Hearing Listeners, Nancy Marie Bowen
Dissertations and Theses
The purpose of this study was to investigate the effects of a 500 Hz and 3150 Hz one-third octave band augmentation on the speech discrimination ability of normal hearing listeners and whether such effects vary with signal presentation level. The augmented portion of monosyllabic words was systematically varied from 5-55dB above the intensity level of the unfiltered version of the words and presented simultaneously to one ear.
