Reliability of clinical voice parameters captured with smartphones – measurements of added noise and spectral tilt
(ISCA, 2019-09-20)Smartphones have become powerful tools for data capture due to their computational power, internet connectivity, high quality sensors and user-friendly interfaces. This also makes them attractive for the recording of ... -
The effects of syllable and sentential position on the timing of lingual gestures in /l/ and /r/
(International Phonetic Association, 2019-08-10)This paper is an ultrasound-based articulatory study of the impact of syllable-position and utterance position on gesture timing in liquid consonants in American, Irish and Scottish English. Mixed effects modelling was ... -
The effects of syllable and utterance position on tongue shape and gestural magnitude in /l/ and /r/
(International Phonetic Association, 2019-08-10)This paper is an ultrasound-based articulatory study of the impact of syllable-position and utterance position on tongue shape and tongue-gesture magnitude in liquid consonants in American, Irish and Scottish English. Mixed ... -
Say again? Individual acoustic strategies for producing a clearly-spoken minimal pair wordlist
(International Phonetic Association, 2019-08-10)People make their speech clearer in difficult conversational contexts using global mechanisms (e.g. “Lombard Speech”) and by targeted enhancements of linguistic constituents (“hyperspeech”). We describe production changes ... -
Say again? Individual articulatory strategies for producing a clearly-spoken minimal pair wordlist
(International Phonetic Association, 2019-08-10)We describe articulatory differences (lingual and labial) between two versions (neutral and clear) of a CVC wordlist of 12 targets (V = /ieaɔoʉ/; C_C = /p_p/ or /m_m/). A companion paper describes the background; the ... -
Bulgarian vowel reduction in unstressed position: An ultrasound and acoustic investigation
(International Phonetic Association, 2019-08-10)Vowel reduction in Contemporary Standard Bulgarian (CSB) has been variously claimed to involve raising, no change or lowering of the high vowels /iəu/. There is a general agreement that the low vowels /ɛaɔ/ are raised when ... -
Inequality in access to hearing care for older adults in residential homes
(Oxford University Press, 2019-07-31)Background The population of older people in residential homes is projected to rise. There are unrecognized hearing difficulties among residents and prevalence of hearing loss in this population is underreported. This can ... -
Systematic review of ultrasound visual biofeedback in intervention for speech sound disorders
(Wiley, 2019-06-10)Background As cost and access barriers to ultrasound technology have decreased, interest in using ultrasound visual biofeedback (U-VBF) as a tool for remediating speech sound disorders (SSD) has increased. A growing body ... -
The impact of aphasia on Internet and technology use
(Taylor & Francis, 2019-04-13)Purpose: This study compared Internet use post-stroke in people with aphasia (n = 25) and without aphasia (n = 17). The purpose was to understand how people with aphasia were using the Internet and to investigate the impact ... -
Towards ordinal classification of voice quality features with acoustic parameters
(ESSV, 2019-03-09)The human voice is capable of fine-grained variation that results in listener attributions of various psychological, social and biological factors. The complexity of this process is reflected in the number and richness ... -
Assessing voice health using smartphones: Bias and random error of acoustic voice parameters captured by different smartphone types
(Wiley, 2019-02-19)BACKGROUND: Occupational voice problems constitute a serious public health issue with substantial financial and human consequences for society. Modern mobile technologies like smartphones have the potential to enhance ... -
Gestural delay and gestural reduction. Articulatory variation in /l/-vocalisation in Southern British English
(Edinburgh University Press, 2019)The vocalisation of /l/, as currently observed in Southern British English (SBE), involves weakening of the consonantal tongue tip (TT) gesture. Such weakening can be conceptualised in terms of spatial reduction, where the ... -
A comparison of acoustic and articulatory parameters for the GOOSE vowel across British Isles Englishes
(Acoustical Society of America, 2019)This study quantifies vocalic variation that cannot be measured from the acoustic signal alone and develops methods of standardisation and measurement of articulatory parameters for vowels. Articulatory-acoustic variation ... -
Secure account-based data capture with smartphone – preliminary results from a study of articulatory precision in clinical depression
(De Gruyter Mouton, 2019)Smartphones provide an attractive way of sourcing data for linguistic researchers, potentially collecting recordings in more natural environments and thus with higher ecological validity than recordings made in a recording ... -
Awareness of and support for speech, language and communication needs in Children’s Hearings
(CELCIS (Centre for Excellence for Looked After Children in Scotland), 2018-12-18)Looked-after children commonly experience speech, language and communication needs (SLCN) (McCool & Stevens, 2011; Department for Education, 2017). Unidentified and unmet SLCN have negative effects on children’s educational ... -
Association of proximal elements of social disadvantage with children's language development at 2 years: An analysis of data from the Children in Focus (CiF) sample from the ALSPAC birth cohort
(Wiley, 2018-11-27)Background: An association between social disadvantage and early language development is commonly reported in the literature, but less attention has been paid to the way that different aspects of social disadvantage affect ... -
Tongue shape dynamics in swallowing using sagittal ultrasound
(Springer, 2018-06-28)Ultrasound imaging is simple, repeatable, gives real-time feedback, and its dynamic soft tissue imaging may make it superior to other modalities for swallowing research. We tested this hypothesis and measured certain spatial ... -
UltraSuite: A Repository of Ultrasound and Acoustic Data from Child Speech Therapy Sessions
(International Speech Communication Association, 2018-06-17)We introduce UltraSuite, a curated repository of ultrasound and acoustic data, collected from recordings of child speech therapy sessions. This release includes three data collections, one from typically developing children ... -
The use of electropalatography in the treatment of speech disorders in children with Down Syndrome: a randomised controlled trial
(2018-06-08)Background: Electropalatography (EPG) records details of the location and timing of tongue contacts with the hard palate during speech. It has been effective in treating articulation disorders that have failed to respond ... -
An ultrasound study of the development of lingual coarticulation during childhood
(Karger, 2018-04-11)Background/Aims. There is growing evidence that coarticulation development is protracted and segment-specific, and yet very little information is available on the changes in the extent of coarticulation across different ...
