Speech intelligibility testing for new technologies
There are several tests of speech intelligibility currently available which employ a variety of methods. The most appropriate method for testing intelligibility of speech transmitted via telephony is a forced choice task in which listeners hear speech samples and identify what they hear from among a set of alternatives displayed onscreen. This methodology allows tests to be run quickly and scor...
متن کاملAdaptive bandwidth measurements of importance functions for speech intelligibility prediction.
The Articulation Index (AI) and Speech Intelligibility Index (SII) predict intelligibility scores from measurements of speech and hearing parameters. One component in the prediction is the "importance function," a weighting function that characterizes contributions of particular spectral regions of speech to speech intelligibility. Previous work with SII predictions for hearing-impaired subject...
متن کاملSpeech Intelligibility and Fire Alarm Systems
Introduction Messages broadcast over Emergency Voice Communication Systems (EVCS) can provide information to help occupants decide what actions to take for different event scenarios, such as fires, weather events, or terrorist attacks. It is imperative, therefore, that people receive content that is comprehensible. Such understanding can be influenced by the message itself, the talker and liste...
متن کاملMode of communication and classroom placement impact on speech intelligibility.
OBJECTIVE To examine the impact of classroom placement and mode of communication on speech intelligibility scores in children aged 8 to 9 years using multichannel cochlear implants. DESIGN Classroom placement (special education, partial mainstream, and full mainstream) and mode of communication (total communication and auditory-oral) reported via parental rating scales before and 4 times afte...
متن کاملA MAP based approach to adaptive speech intelligibility measurements
This paper presents an adaptive procedure applied to measurements of speech intelligibility using the modified rhyme test. It is argued that the required speech-to-noise (SNR) ratio could be estimated with sufficient accuracy with as few as 25 utterances. The present procedure is based on the maximum a posteriori criterion, and it is demonstrated how the standard deviation of the SNR estimate c...
