Listening Tasks: Listener participants will listen to pre-recorded speech samples obtained from the tripod-mounted microphones. Speech samples will be played in a randomized order. Listeners will not be present at the time speech samples are recorded, and they will be blinded to all information about the speakers and to the contents of the sentences from both the SIT and picture description tasks prior to hearing them. Listeners will be seated at a comfortable distance from a loudspeaker, which will be fixed at a comfortable predetermined volume, and they will be asked to transcribe the data orthographically on prepared forms that will be numbered to match the presentation order of the stimuli. The SIT software will compute an intelligibility score by comparing transcribed words and sentences to the stimuli on the master lists. For the picture description task, sentences will be transcribed independently by the assessor and then compared to the listeners' transcriptions to determine the intelligibility score.
