Ultrasound Images of the Tongue: A Tutorial for Assessment and Remediation of Speech Sound Errors

23.1K
Ultrasound imaging can be used to display the shape and movements of the tongue in real time during speech. The images can be used to determine the nature of speech sound errors. Visual feedback of the tongue can be used to facilitate improvements in speech sound production in clinical populations.

Design Consideration

556
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key...

Transmission Line Design Considerations

605
Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

Study Design for Navigated Repetitive Transcranial Magnetic Stimulation for Speech Cortical Mapping

1.9K
Navigated repetitive transcranial magnetic stimulation is a highly efficient non-invasive tool for mapping speech-related cortical areas. It helps in designing brain surgery and speeds up the direct cortical stimulation conducted during the surgery. This report describes how to perform speech cortical mapping reliably for preoperative evaluation and research.

Area of Science:

  • Augmentative and Alternative Communication (AAC)
  • Speech-Language Pathology
  • Human-Computer Interaction

Background:

  • Millions of Chinese-speaking individuals with severe speech disorders face significant barriers to societal participation.
  • Current methods for entering Chinese text into computer systems are complex, hindering adaptive access for those reliant on assistive technology.
  • Speech Generating Devices (SGDs) offer potential but require effective input methods for Chinese language.

Purpose of the Study:

  • To examine phonetic and logographic input methods for Chinese text entry on computer systems.
  • To evaluate the advantages and disadvantages of these input methods for individuals with complex communication needs.
  • To identify optimal strategies for enhancing computer accessibility for Chinese-speaking SGD users.

Main Methods:

  • Analysis of two primary input method categories: phonetic and logographic principles.
  • Evaluation of the complexities and translation requirements inherent in each input system.
  • Assessment of suitability for specific populations with diverse communication requirements.

Main Results:

  • Phonetic input methods may offer broader accessibility but can involve complex phonetic-to-character mapping.
  • Logographic input methods, while potentially more direct for character representation, can be challenging due to the vast number of characters.
  • Both methods present unique challenges and benefits depending on the user's specific communication profile and cognitive abilities.

Conclusions:

  • The choice of input method for Chinese SGDs significantly impacts user experience and functional communication.
  • Further research is needed to optimize both phonetic and logographic systems for improved adaptive access.
  • Tailoring input methods to individual user needs is crucial for maximizing the benefits of SGDs in the Chinese-speaking population.
