Suppressing Steady-state Portions of Speech for Improving Intelligibility in Various Reverberant Environments
In previous studies (Arai et al., 2001; Arai et al., 2002), we hypothesized that segments of an acoustic signal are masked by reverberation components of previous segments, degrading speech intelligibility. To reduce masking influences, we suppressed steady-state portions having more energy, but which are less crucial for speech perception. We have presently conducted a perceptual test with a s...
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...
متن کاملDecreasing speaking-rate with steady-state suppression to improve speech intelligibility in reverberant environments
1. Introduction It is known that strong reverberation affects speech intelligibility. Although early reflections often help speech intelligibility (the Haas effect, e.g., [1]) late reflections degrade speech intelligibility [2]. Overlap-masking in rever-berant environments is the main source of degradation in speech intelligibility [3–5]. Because of overlap-masking, reverberant components of pr...
متن کاملA preprocessing technique for improving speech intelligibility in reverberant environments: the effect of steady-state suppression on elderly people
In a large auditorium, perceiving speech may become difficult. One reason that reverberation degrades speech intelligibility is the effect of overlap-masking (Bolt and MacDonald, 1949; Nabelek and Robinette, 1978). Reverberation is a more critical issue for elderly people to perceive speech than it is for young people (Fitzgibbons and Gordon-Salant, 1999). Arai et al. suppressed steady-state po...
متن کاملEffects of suppressing steady-state portions of speech on intelligibility in reverberant environments
1. Introduction When listening to a lecture in a large auditorium it is often difficult to understand the speech. Among other factors, comprehension may be impaired by reverberation, which is sound reflecting from the wall, interfering with direct sound. Based on the modulation transfer function (MTF), the speech transmission index (STI) has been proposed as an objective measure for speech inte...
