概括
大多数患有失言症的人不会将眼睛的运动与文本转化为语音 (TTS) 听觉输出同步. 这种缺乏模式同步可能会限制TTS技术对患有失语症的人的有效性.
科学领域:
- 神经科学是一个神经科学.
- 语音和语言病理学 语言病理学
- 人与计算机的交互
背景情况:
- 文字转化为语音 (TTS) 技术提供双模式 (听觉和视觉) 的内容呈现.
- 眼睛固定与听觉词汇呈现的同步对于TTS在失语症中的好处至关重要.
- 有限的研究存在于TTS使用阿法西亚患者的模式同步成就.
研究的目的:
- 通过使用TTS来调查TTS使用的失言症患者的模式同步的程度和频率.
- 检查阅读理解,阅读速度和模式同步之间的关系.
主要方法:
- 追溯分析九个成年人的眼睛跟踪数据与失语处理TTS通道.
- 模式同步定义为在特定时间窗口内发生的眼睛固定,与听觉文字呈现相比.
- 同步百分比和标准化阅读测试成绩之间的相关性分析.
主要成果:
- 只有三个参与者表现出一致的模式同步 (67-76%的单词).
- 一名参与者有不一致的同步 (58%),而五名参与者很少同步.
- 在阅读理解得分和模式同步之间发现了显著的正相关性.
结论:
- 默认的TTS速率并不能确保大多数失语患者的双模同步.
- 缺乏同步可能解释了TTS对这一群体的可变好处.
- 需要进一步的研究来优化TTS呈现以支持失言症.

01:10Higher Mental Functions of the Brain: Language
848
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

333
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

01:27Language and Cognition
346
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
