This study investigated the development of spatial release from masking in children using closed-set Mandarin disyllabic words and monosyllabic carrying lexical tones as test stimuli speech spectrum-weighted noise a masker.Twenty-six ages 4-9 years 12 adults, all with normal hearing, participated recognition tests under 2 conditions: (a) spatially mixed presented front (NF), (b) separated side (NS) different signal-to-noise ratios (SNRs). Performance-SNR psychometric functions were obtained...
This study investigated the contributions of temporal periodicity cues and effectiveness enhancing these for Cantonese tone recognition in noise. A multichannel noise-excited vocoder was used to simulate speech processing cochlear implants. Ten normal-hearing listeners were tested. Temporal envelope (TEPCs) below 500Hz extracted from four frequency bands: 60–500, 500–1000, 1000–2000, 2000–4000Hz. The test stimuli obtained by combining TEPC-modulated noise signals individual bands. For...
To compare the speech perception performance of older adults with that adult cochlear implant (CI) recipients in a single center Hong Kong.A retrospective study 14 CI users (age at operation, 56 to 77 yr old) and 18 53 who received CIs were matched for duration profound deafness. The outcome indicator their includes ratings 0 7 on category (SPC), which is based test scores 6, 12, 24 mo after implantation. Statistical analyses used SPC between two groups tested intervals. Results specific...
AbstractAbstractThe benefits of bimodal hearing (cochlear implant and aid in opposite ears) children are well documented English-speaking populations (Ching et al., 2000; Holt 2005) but not much evidence has been reported from using tonal languages. The lexical tones languages heavily loaded with semantic grammatical information, which essentially represented by the fundamental frequency (F0) low-order harmonics speech signal. This unique linguistic feature means that language-speaking CI...
MAPPID-N was developed to assess the speech-recognition abilities in noise of Mandarin-speaking children on disyllabic words, and lexical tones monosyllabic a picture-identification test format. Twenty-six normal-hearing aged four nine years listened repeatedly materials where spatially mixed with or separated from speech, different signal-to-noise (SNR) ratios, obtain performance-SNR functions SNR for 50% correct scores (SNR-50%). SNR-50% improved age only when speech but not suggesting...
Temporal envelope and periodicity components (TEPC) in the speech signal have potentials to offer important cues for recognition especially tonal languages. The aims of this study are: (i) investigate degree contributions TEPC lexical tone identification Cantonese; (ii) whether or not vary among different frequency bands. results these investigations would reveal if there are any frequency-specific that identification.TEPC monosyllable words carrying tones, were extracted by method full-wave...
Two Cantonese-speaking children with cleft palate participated in an EPG treatment programme focused on sibilants. Remediation was rapid, and systemic changes occurred as a result of generalization. Implications for the description nature affricates, their developmental route difficulty they pose speech disorders are addressed. The findings discussed within model output constraints according to theory phonological neighbourhood complexity.
The amplification outcomes of two hearing aid prescriptions, NAL-NL1 and Digital Perception Processing (DPP), nine moderate to moderately severe hearing-impaired adults were compared in the same digital instrument. aims at optimizing speech intelligibility while amplifying signal a normal overall loudness level (Dillon, 1999). DPP focuses on restoring based impaired cochlear excitation models (Launer Moore, 2003). In this comparison, resulted better sentence recognition performance than...
Children with hearing loss who require special school placement may have a wide range of audiometric configurations. Since such children will vary in auditory status their amplification requirements also be diverse. This study examined the audiological records 231 attending four schools for impaired Hong Kong to gain an understanding common patterns found and rehabilitation needs.Data on children's aetiology loss, status, tympanometric findings electroacoustic characteristics aids were...
This paper describes a study on the effectiveness of expanding temporal envelope and periodicity component (TEPC) for Cantonese tone perception. The ultimate goal is to develop speech processing techniques that can improve perception hearing prosthesis users. popular Chinese dialect with complex lexical system. TEPCs are extracted from few predefined frequency bands. A nonlinear expansion method applied increase modulation depth TEPCs, in order make information more salient. To simulate...
One of the recent developments in education speech-language pathology is to include literacy disorders and learning disabilities as key training components curriculum. Disorders reading writing are interwoven with speaking listening, which should be managed holistically, particularly children adolescents. With extensive clinical linguistics, language disorders, other theoretical knowledge skills, pathologists (SLPs) best equipped most competent professionals screen, identify, diagnose,...

CANDILET-N is a closed-set speech-recognition test to assess lexical tone recognition in noise for Cantonese speakers. The consists of 60 items four-alternative forced-choice paradigm, with male and female speaker versions. Each plate two disyllabic-word minimal pair their respective phonemic distracters. Psychometric performance SNR (signal-to-noise ratio) functions from 26 normal hearing adult subjects were fitted logistic regression model obtain the 50% correct score (SNR-50%) individual...
Temporal envelope and periodicity components (TEPCs) in the speech signal offer important cues for recognition. A recent study revealed that TEPCs extracted from high-frequency regions contribute significantly to Cantonese lexical tone recognition at monosyllabic word level (Yuen et al., 2006). The aim of current was compare contributions different frequency connected speech, using same or noise band carriers a very limited number bands. Test stimuli were disyllabic minimal pairs differing...
ABSTRACT Children with disordered speech patterns have particular difficulties fricatives and affricates, it is also well documented that these segments are vulnerable in children cleft palate (Grunwell, Sell & Harding, 1993). This the case for both English‐speaking Cantonese‐speaking children. The sibilant system Cantonese differs from English several ways: there no voiced cognates, affricates alveolar, only five (/f/, /s/ /ts/ /ts h / /h/). We hypothesised teaching fricative (grooving)...
