Contrastive Linguistics

• Consonant sounds can be classified as bilabial, labiodental, dental, alveolar, palatal, velar, glottal, and nasal consonants.
• The positioning of the tongue affects vowel production, with front-tongue positions producing high vowels (i/e) and back-tongue positions producing low vowels (a).
• Vowel sounds are produced by the vocal cords vibrating to create sound waves that pass through the mouth and nose.
• Tone is an important feature of many languages, including Chinese, Vietnamese, Thai, Lao, Burmese, Khmer, and some African languages.
• Contrastive analysis can be used to develop teaching materials, assess language proficiency, and inform second-language acquisition research.
• Contrastive analysis can be used as an aid in language learning, teaching, translation, and second-language acquisition research.
• Labiodental consonants are formed by closure of the upper lip with the lower teeth, such as /f/ and /v/.
