まとめ
オーストラリア英語のコダ音では,はっきりとした音のジェスチャーによって音が聞こえなくなります. コダ /t/ は収縮を用い, /k/ と /s/ は広がりを用い, /p/ は中間の動作を示している.
科学分野:
- 言語学
- 音声学
- 音響分析
背景:
- 声の無さは,状の広がり (呼吸困難) または収縮 (状化) によって引き起こされる.
- 英語のコダ音はしばしば特定の音のジェスチャーを含みますが,オーストラリア英語の直接的な測定は限られています.
研究 の 目的:
- オーストラリア英語のコダ音 /p,t,k,s/ の無音化に起因する音のメカニズム (広がり vs.収縮) を調べる.
- コダの前の母音の 音学と電光学を分析する
主な方法:
- エレクトログラトグラフィー (EGG) と音響分析を用いた.
- オーストラリア英語の無音コダ /p,t,k,s/ の前の母音を分析した.
主要な成果:
- コダ / t / は,グルタル収縮と関連していました.
- /k/ と /s/ のコダは 球状の広がりを示した.
- /p/は中途半端な グロータルジェスチャーを示した.
結論:
- オーストラリアの英語では,少なくとも2つの異なるグラタル戦略が使われています.
- これらの戦略は,発音の場所と潜在的に母音のアイデンティティによって影響を受けるようです.

01:24Components of Language
392
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

01:11The Auditory Ossicles
2.0K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:27Language and Cognition
440
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.

01:10Tip-of-the-Tongue Phenomenon
226
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
721
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
