In mobile devices, perceived speech signal degrades significantly in the presence of background noise as it reaches directly at the listener's ears. There is a need to improve the intelligibility and quality of the received speech signal in noisy environments by incorporating speech enhancement algorithms. This paper focuses on speech enhancement method including auditory masking propertie...
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...
In this study, we investigated whether the intelligibility-enhancing mode of speech production, known as “clear speech” produced by native and non-native talkers influenced speech intelligibility equally for native and non-native listeners. In a series of three experiments, we explored the effect of clear speech for various native and non-native talker and listener pairs. Combined, the results ...
The aim of present study is to evaluate and compare speech intelligibility in hearing impaired children with cochlear implants (CI) and hearing aid (HA) users and children with normal hearing (NH). The sample consisted of 45 Persian-speaking children aged 3 to 5-years-old. They were divided into three groups, and each group had 15, children, children with CI and children using hearing aids in H...
OBJECTIVE This study aimed to evaluate the long-term speech perception and speech intelligibility of congenitally and prelingually deaf children after cochlear implantation. It was a longitudinal study following 63 congenitally or prelingually deaf children up to 5 years after implantation. They each received a nucleus multichannel cochlear implant before they were 10 years old. METHODS Perce...
The effect of masking due to fluctuating sources on speech intelligibility is a phenomenon difficult to predict. Intelligibility scores vary with the efficiency of the energetic masking while the linguistic content of the message and listener’s cognitive performances add to the general incertitude that peaks for the case of masking speech. The present contribution proposes a signal-based assess...
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...
Dysarthria is a motor speech impairment affecting millions of people. Dysarthric speech can he far less intelligible than that of non-dysarthric speakers, causing significant communication difficulties. The goal of this work is to understand the effect that certain modifications have on the intelligibility of dysarthric speech. These modifications are designed to identify aspects of the speech ...
This study investigated the intelligibility of native and Mandarin-accented English speech for native English and native Mandarin listeners. The word-final voicing contrast was considered (as in minimal pairs such as `cub' and `cup') in a forced-choice word identification task. For these particular talkers and listeners, there was evidence of an interlanguage speech intelligibility benefit for ...
We investigated the speech intelligibility differences of normal and bone-conduction stereo headphones of target speech localized at 45◦ on the horizontal plane when competing noise is present. This was our effort to study the possible effect of crosstalk found in bone-conduction headphones on speech intelligibility. All sound sources were localized on the horizontal plane. Target speech was lo...
