The organization and function of sounds within a language
Explication
Phonology is the study of how sounds function and are organized within a language, focusing on sound patterns and systems rather than individual sounds or their physical production.
20
Explication
The correct answer is 20 because the content states that English has approximately 20 vowel sounds in speech, which is a key fact about phonetics and vowel articulation.
To produce and shape speech sounds by modifying airflow
Explication
The primary role of speech organs is to produce and shape speech sounds by modifying airflow in the vocal tract, enabling clear and distinct pronunciation.
In the 19th century
Explication
The concept of vowel articulation was first systematically studied and established as part of phonetics during the 19th century, with scholars like Henry Sweet and Daniel Jones developing the classification of vowels.
Consonant articulation involves constriction of airflow, while vowel articulation involves an open vocal tract.
Explication
Consonant articulation involves constriction or obstruction of airflow in the vocal tract, whereas vowel articulation involves an open vocal tract without significant constriction, making this the key difference.
Hermann von Helmholtz
Explication
Hermann von Helmholtz is credited with pioneering the study of the physical and acoustic properties of sounds, including speech sounds, laying the groundwork for acoustic phonetics.
It helps learners produce more accurate pronunciation
Explication
Using phonetic transcription helps learners produce more accurate pronunciation by providing a precise visual representation of speech sounds, which enhances their ability to learn correct pronunciation.
By consciously varying pitch and stress to convey different emotions and grammatical meanings
Explication
The correct answer is to consciously vary pitch and stress, as suprasegmental features like intonation, stress, and rhythm are used to convey emotions, emphasis, and grammatical distinctions in speech. This practical application enhances communication effectiveness and naturalness.
English has approximately 20 vowel sounds and 24 consonant sounds in speech.
Explication
The correct answer is that English has approximately 20 vowel sounds and 24 consonant sounds in speech, which highlights the complexity of its sound system compared to its alphabet. This is a key feature because it shows that the number of spoken sounds exceeds the number of written vowels and consonants, reflecting the richness of English pronunciation.
