Final answer:
Transcription of the words 'pot, job, got, and stock' in SBE and GA requires the use of IPA and an understanding of accent pronunciation, which is not fully covered here. Words with short and long sounds differ in their vowel openness. Identifying letters representing certain sounds, like [k] and [b], shows their variable spelling.
Step-by-step explanation:
To transcribe the words pot, job, got, and stock in Standard British English (SBE) and General American (GA), we need to consider the phonetic differences between these two accents, particularly in the pronunciation of vowels and certain consonants. However, you're asking for a transcription, which requires knowledge of the International Phonetic Alphabet (IPA) and specific pronunciation standards of these regional accents, which may be beyond the scope here.
When considering the sounds of short and long as in words like question and these, we find that both accents may pronounce them slightly differently. Words with a short sound, such as then and rent, have a more open vowel sound compared to the long sound in words like believe and leave.
As for underlining letters that represent certain sounds, like [k] in truck, stock, make, bark, and embark, or the letter [b] in able, scribble, resemble, pebble, tremble, noble, gamble, and bubble, this helps highlight the different ways these sounds can be spelled in English.
