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:

概括

视觉语音提示,如部运动,有助于人们更好地理解语音,特别是在杂的环境中. 这种视觉语音节奏信息有助于语音感知,即使有外国口音.

科学领域:

  • 听觉和视觉感知是听觉和视觉感知.
  • 语音沟通 语音沟通
  • 语音学 语音学 语音学

背景情况:

  • 视觉语音信息可以增强语音感知.
  • 以视觉方式传达的语音节奏的作用是不太了解的.
  • 外国口音可以影响语音感知和视觉线索的实用性.

研究的目的:

  • 调查视觉语言是否提供了可用于语音感知的节奏信息.
  • 为了确定如何节奏熟悉,受外国口音的影响,影响视觉语言的好处.
  • 探索视觉节奏线索在音视觉语音感知中的贡献.

主要方法:

  • 与澳大利亚英语听众一起进行了噪音语音感知任务.
  • 来自母语和非母语英语使用者 (不同的口音) 的句子以音频单独 (AO),口罩音频视觉 (AVm) 和音频视觉 (AV) 条件呈现.
  • 后续实验检查了在听力改善的情况下,具有强烈外国口音的言语.

主要成果:

  • 在所有口音类型中,语音识别在AV条件中是最好的.
  • 视觉语音 (AVm) 对熟悉的节奏 (没有/弱口音) 的识别比AO更好,但对不熟悉的节奏 (强口音) 没有.
  • 没有发现视觉线索 (AVm与AO) 对强烈的外语口音发言有任何益处,即使在更可听的条件下.
