J Speech Lang Hear Res
. 2021 Nov;
65(1):5-21.
PMID: 34843405
Purpose: The goal of this study was to examine the effects of increases in vocal effort, without changing speech intensity, on respiratory and articulatory kinematics in young adults with typical...

PMID: 34621100
Speech nasalization is achieved primarily through the opening and closing of the velopharyngeal port. However, the resultant acoustic features can also be influenced by tongue configuration. Although vowel nasalization is...

PLoS One
. 2020 Apr;
15(4):e0231484.
PMID: 32287289
Purpose: This study aimed to evaluate the role of motor control immaturity in the speech production characteristics of 4-year-old children, compared to adults. Specifically, two indices were examined: trial-to-trial variability,...

J Speech Lang Hear Res
. 2019 Sep;
62(10):3655-3666.
PMID: 31525305
Purpose Previous studies of speech articulation have shown that individuals who can perceive smaller differences between similar-sounding phonemes showed larger contrasts in their productions of those phonemes. Here, a similar...

J Speech Lang Hear Res
. 2017 Dec;
60(12):3404-3416.
PMID: 29204608
Purpose: This study examined the relationship between the magnitude of neck-surface vibration (NSVMag; transduced with an accelerometer) and intraoral estimates of subglottal pressure (P'sg) during variations in vocal effort at...

. 2016 Oct;
59(5):1025-1034.
PMID: 27701628
Purpose: The purpose of this study was to determine the effects of biofeedback on control of nasalization in individuals with typical speech. Method: Forty-eight individuals with typical speech attempted to...
