American English Pronunciation Learning Tips:
— The American English pronunciation system is markedly different from the British English pronunciation system. First and foremost, there is a greater variance in vowel sounds in American English. For example, the vowel sound in “bat” is pronounced as “ah” in British English, but as “aht” in American English. Additionally, consonants are often pronounced differently.
— American English pronunciation is different than other types of English because the accent is more emphasized on certain syllables than others. For example, the letter “a” is typically pronounced as “ah” in American English, whereas in British English, it is pronounced as “ay”. Additionally, the letter “r” is typically pronounced as “ah” in American English, whereas in British English, it is pronounced as “arr”.
— The pronunciation of American English is different than the pronunciation of British English. American English has a more “flat” sound, while British English has a more “rounded” sound. This is due to the differences in the vowel sounds between the two dialects. In American English, the “a” sound is more like the “ah” sound, and the “e” sound is more like the “eh” sound.
— The pronunciation of American English is often difficult for people from other countries to understand. This is because Americans use a lot of complex academic jargon that is not used in other varieties of English. For example, they might say “I’m gonna” instead of “I’m going to” or “shoulda” instead of “should have”. They might also pronounce words differently than people from other countries.
— The pronunciation of American English is typically characterized by the use of rhotic vowels. This means that speakers will typically pronounce the letter “r” in words like “car” and “star”, regardless of whether or not it is actually present in the word. Additionally, American English typically has a higher pitch than other varieties of English, and its rhythm is often more pronounced.
— The pronunciation of American English is distinguished by certain features, most notably the use of rhoticity. This refers to the pronouncing of the letter “R” in words like “hard” and “card”, which is not found in many other varieties of English. In addition, American English typically has a higher pitch than other variants, and a more open vowel sound in words like “kit” and “sit”.
