This study investigated the extent to which noise impacts normal-hearing young adults' speech processing of sentences that vary in intelligibility. Intelligibility and recognition memory in noise were examined for conversational and clear speech sentences recorded in quiet (quiet speech, QS) and in response to the environmental noise (noise-adapted speech, NAS). Results showed that (1) increase...

Recently permutation multimedia ciphers were broken in a chosen-plaintext scenario. That attack models a very resourceful adversary which may not always be the case. To show insecurity of these ciphers, we present a cipher-text only attack on speech permutation ciphers. We show inherent redundancies of speech can pave the path for a successful cipher-text only attack. To that end, regularities ...

OBJECTIVE Reduced intelligibility is a central concern in speech-impaired children, especially for parents. The main purpose of this study was to develop normative data for the intelligibility of Flemish-speaking boys and girls (age 2;06-5;0 years) as judged by their parents. Additionally, the influence of familiarity, gender and age of the child was determined. PATIENTS AND METHODS Word, sen...

This paper uses listening tests to directly evaluate two speech pre-enhancement algorithms that were published in earlier work. The models were previously evaluated using purely objective measures. The methods under study aim to increase speech intelligibility by applying an adaptive spectral shaping filter to the speech signal. In both algorithms the shape of the filter is adapted so as to max...

When a target-speech/masker mixture is processed with the signal-separation technique, ideal binary mask (IBM), intelligibility of target speech is remarkably improved in both normal-hearing listeners and hearing-impaired listeners. Intelligibility of speech can also be improved by filling in speech gaps with un-modulated broadband noise. This study investigated whether intelligibility of targe...

Purpose A single-word identification test was used to study speech production in children and adults with Down syndrome (DS) to determine the developmental pattern of speech intelligibility with an emphasis on vowels. Method Speech recordings were collected from 62 participants with DS aged 4-40 years and 25 typically developing participants aged 4-7 years. Panels of 5 adult lay listeners tra...

Running Title: Syllable intelligibility for ltered cepstral trajectories Received: T. Arai et al., \Syllable intelligibility for ltered cepstral trajectories," JASA 2 Abstract We measured the intelligibility of syllables whose cepstral trajectories were temporally ltered. The speech signals were transformed to their LPC cepstral coeecients, and these coeecients were passed through diierent lter...
