This next sound is in many ways the KEY to British Standard English Pronunciation because it occurs again and again and again. It is the neutral vowel or schwa:
“uh” as in “another”
The lips are neutral and the centre of the tongue is half raised. You will find this sound not only in most unstressed syllables, but it is also to be found in 4 of the 8 diphthongs and in all 5 of the triphthongs. The “uh” sound is particularly important to American speakers when they learn the British accent. Generally, it will be a mistake with this sound which will give away an American speaker. We will start with the word “another” where the neutral vowel is both the first and third syllable.
