Assessment of Ventilation II: Respiratory Depth and Rhythm

1.6K
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Summary
This summary is machine-generated.

Visual speech cues, like jaw movements, help people understand speech better, especially in noisy environments. This visual speech rhythm information aids speech perception even with foreign accents.

Area of Science:

  • Auditory and Visual Perception
  • Speech Communication
  • Phonetics

Background:

  • Visual speech information can enhance speech perception.
  • The role of speech rhythm conveyed visually is less understood.
  • Foreign accents can impact speech perception and the utility of visual cues.

Purpose of the Study:

  • To investigate if visual speech provides rhythm information usable for speech perception.
  • To determine how rhythm familiarity, influenced by foreign accents, affects the benefit of visual speech.
  • To explore the contribution of visual rhythm cues in audio-visual speech perception.

Main Methods:

  • A speech perception in noise task was conducted with Australian English listeners.
  • Sentences from native and non-native English speakers (varying accents) were presented in Audio-Only (AO), Audio-Visual with mouth covered (AVm), and Audio-Visual (AV) conditions.
  • A follow-up experiment examined speech with a strong foreign accent under improved audibility.

Main Results:

  • Speech recognition was best in the AV condition across all accent types.
  • Visual speech (AVm) improved recognition over AO for familiar rhythms (no/weak accent) but not for unfamiliar rhythms (strong accent).
  • No benefit of visual cues (AVm vs. AO) was found for strong foreign accent speech, even in more audible conditions.

Conclusions:

  • Visual speech rhythm, potentially conveyed by jaw motion, aids speech perception.
  • The effectiveness of visual rhythm cues depends on rhythm familiarity and the degree of foreign accent.
  • Visual speech information, including rhythm, is crucial for robust speech perception in challenging listening conditions.
