Comparison of Nasalance Measurements from Accelerometers and Microphones and Preliminary Development of Novel Features
نویسندگان
چکیده
This study compares four nasalance measures computed as ratios between the amplitude of signals recorded with accelerometers and microphones. Two new measures based on RMS amplitude differences between the nasal signal and either the vocal folds vibration signal (LND) or the oral acoustic signal (OND) are introduced. Measures were compared on a total of 584 utterances produced by four native French speakers. Results show that (1) all measures separate nasal from oral consonants, (2) the different experimental setups cannot be considered equivalent, (3) difference-based measures appear to better describe the time course of nasality than ratio-based measures.

A Novel System-Level Calibration Method for Gimballed Platform IMU Using Optimal Estimation
An accurate calibration of inertial measurement unit errors is increasingly important as the inertial navigation system requirements become more stringent. Developing calibration methods that use as less as possible of IMU signals has 6-DOF gimballed IMU in space-stabilized mode is presented. It is considered as held stationary in the test location incorporating 15 di...
متن کاملEstimation of transpalatal nasalance during production of voiced stop consonants by noncleft speakers using an oral-nasal mask.
OBJECTIVE Our objective was to estimate nasalance due to transpalatal transfer of acoustic energy during production of voiced stop consonants by noncleft speakers. We also determined the relationship between the transpalatal nasalance and fundamental frequency (F0) of the speakers. METHOD Participants were 8 men and 10 women (mean age = 21.9 years, SD = 4.0) without cleft palate who produced ...

Background and purpose: Proper resonance is a major factor for the comprehension of speech in individuals with hearing loss. These people have low speech intelligibility caused by inappropriate resonance. Therefore, nasalance measurement is a principal aspect of the assessment of people with hearing loss. This study aimed at determining nasalance in children with hearing loss. Materials and me...

متن کاملDevelopment and Validation of the Preliminary Version of Brief Inpatient Satisfaction Scale (BISS)
Background and Objectives: Questionnaire-based survey is the most common way of assessing patient satisfaction. However, most relevant survey instruments have been developed in western countries, and valid and reliable context-specific survey tools in this area are lacking. To help filling this gap, in this study we have developed and validated the preliminary version of the novel Brief Inpatie...
