A great number of rooms are dedicated to a voice communication between a singular speaker and a group of listeners. Those rooms could be as small as meeting room and classrooms or larger like auditoriums and theatres. There is a major demand for them to assure the highest possible speech intelligibility for all listeners in the room. Classrooms are an example of rooms where a very good speech i...

This study examined the influence of mixing faces and voices on the audiovisual intelligibility. The goal is to study the effect of combining two sources of information on the audiovisual intelligibility. Cross-talker dubbing was performed between faces and voices of 10 meaningful sentences pronounced by 10 talkers: 5 females and 5 males. Human subjects were asked to rate the articulation of th...

The speech intelligibility index (SII) (ANSI S3.5-1997) provides a means for estimating speech intelligibility under conditions of additive stationary noise or bandwidth reduction. The SII concept for estimating intelligibility is extended in this paper to include broadband peak-clipping and center-clipping distortion, with the coherence between the input and output signals used to estimate the...

Increased global interaction has led to increased communication between individuals with wide ranging linguistic experience. As a consequence, the ramifications of accent in speech production need to be better understood. It is plausible that differences in speech intelligibility due to accent type affect gross intelligibility in different ways. These differences may be differentially affected ...

Based on the noise-replacement paradigm, recent studies showed that vowels carried more perceptional information for sentence intelligibility than consonants. Considering that vowels contain many important acoustic cues for speech perception, this study further assessed the effect of spectral degradation to the intelligibility of Mandarin vowel sentences. Mandarin sentences were processed to ge...

OBJECTIVE In persons with a speech pathology, improved intelligibility is the fundamental goal of treatment. Identification of specific phonetic features that affect intelligibility, contributes to selecting intervention targets. The main purpose of this study was to investigate whether a segmental analysis based on a perceptual phoneme intelligibility assessment is reliable and can be used for...

Studies on fast speech have shown that word-level timing of fast speech differs from that of normal rate speech in that unstressed syllables are shortened more than stressed syllables as speech rate increases. An earlier experiment showed that the intelligibility of time-compressed speech could not be improved by making its temporal organisation closer to natural fast speech. To test the hypoth...

PURPOSE The purpose of this study was to compare men with women in terms of speech intelligibility, to investigate the validity of objective acoustic parameters related with speech intelligibility, and to try to set up the standard data for the future study in various field in prosthodontics. MATERIALS AND METHODS Twenty men and women were served as subjects in the present study. After record...

Mand functions for two stimuli (A1 and A2) were trained for 3 children with autism and were then incorporated into two related conditional discriminations (A1-B1/A2 -B2 and B1-C1/B2-C2). Tests were conducted to probe for a derived transfer of mand response functions from A1 and A2 to C1 and C2, respectively. When 1 participant failed to demonstrate derived transfer of mand response functions, t...
