Anotace:

The goal of the project is to address remediation and learning of speech sounds by evaluating the use of ultrasound tongue imaging as a visual feedback and exploring the link between speech production and perception. Although the ultrasound method has already shown positive results in clinical setting, it needs to be tested more thoroughly on larger sample of speakers, across different groups and evaluated over time. The method will be used for speech remediation in children with speech sound disorders and in adults learning a foreign language, as well as for learning isolated novel speech sounds in typical children and adults. The project objectives will be achieved via speech training employing ultrasound tongue imaging and comparing it to training with traditional methods used in clinical practice and foreign language learning. The success of the training will be evaluated with articulatory and acoustic analysis of pre- and post-training tokens, and with native listeners’ perceptual evaluation. The effect of trained production on perception will be assessed by comparing perceptual evaluation of participants’ own speech pre- and posttraining. The project will result in practical guidelines for clinical practice and foreign language teaching, with a potential for direct socio-economic impact by shortening the treatment and learning time. The outcomes will further enhance current understanding of perception-production influence in speech sound training. This interdisciplinary project will merge my experience in ultrasound tongue imaging, clinical speech research and practice, with the expertise of the host in foreign language speech, and it will bring ultrasound tongue imaging method to Czech Republic. As such, the project ensures acquisition and transfer of knowledge for both partners and opens opportunities for long-term carrier establishment of the fellow within academia and/or clinical practice.
