Intelligibility of speech spoken in noise/reverberation for older adults in reverberant environments
Speech intelligibility is in general lower for older adults than young adults in reverberant environments such as train stations or airports. We aim at to make speech announcements intelligible in public spaces. Speech spoken in noise, i.e., noiseinduced speech, is usually more intelligible than speech spoken in a quiet environment for young people when they are heard in noise, a phenomenon cal...
متن کاملIntelligibility of speech spoken in noise and reverberation
When we speak in an environment with noise, we often modify our speech production, and speech spoken in noise is generally more intelligible than speech produced in a quiet environment, which is known as the Lombard effect. Our goal is to provide intelligible speech announcements in noisy and/or reverberant public spaces, such as train stations. Thus, the present paper examines whether speech s...
متن کاملElderly listeners with low intelligibility scores under reverberation show degraded subcortical representation of reverberant speech
In order to elucidate why many elderly listeners have difficulty understanding speech under reverberation, we investigated the relationship between word intelligibility and auditory brainstem responses (ABRs) in 28 elderly listeners. We hypothesized that the elderly listeners with low word intelligibility scores under reverberation would show degraded subcortical encoding information of reverbe...
متن کاملImproving speech synthesis for high intelligibility under adverse conditions
We investigate methods of improving the intelligibility of synthetic speech under noisy or low-fidelity acoustic conditions. Techniques explored improve speech in a natural manner, such that training won’t be required for the user to understand the enhanced speech. While the improvements are natural in this respect, the changes aren’t limited to creating only speech that is achievable by a huma...
متن کاملDesigning modulation filters for improving speech intelligibility in reverberant environments
In this paper, we propose a new technique to design modulation filters to reduce degradation of speech intelligibility in reverberant environments. Using the inverse modulation transfer function, we design data-derived modulation filters for each speech frequency band. These filters preprocess speech signals between a microphone and a loudspeaker that radiates speech into a performance hall. Us...
