Non-Verbal Cues01:29

Non-Verbal Cues

698
Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

16.8K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

5.9K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Area of Science:

  • Speech Pathology
  • Biomedical Engineering
  • Machine Learning

Background:

  • Hypernasality is a key speech characteristic in cleft palate (CP) patients.
  • Current hypernasality grading relies on subjective clinical experience, impacting diagnostic accuracy.
  • Accurate grading is crucial for determining the need for follow-up surgical interventions.

Purpose of the Study:

  • To develop an automated system for objective hypernasality grading in CP speech.
  • To enhance the diagnostic process for CP speech disorders.
  • To provide a reliable tool for assessing the severity of hypernasality.

Main Methods:

  • Utilized a database of CP speech from Sichuan University.
  • Extracted speech features including pitch, energy bands, cepstrum, MFCC, and short-time energy.
  • Employed a K-Nearest Neighbors (KNN) classifier for automatic grading into four severity levels.

Main Results:

  • The automated system achieved an 80.4% classification rate for four hypernasality grades.
  • Demonstrated good performance in distinguishing between normal, mild, moderate, and severe hypernasality.
  • Investigated the influence of gender on the proposed feature set.

Conclusions:

  • The proposed automated system offers a promising approach for objective hypernasality assessment in CP speech.
  • This technology can potentially standardize and improve the evaluation of speech in cleft palate patients.
  • Further research can refine features and explore gender-specific adjustments for enhanced accuracy.
