Subtle changes on an individual level include how the letter 'a' sounds like in the words "castle", "dance", "chance", "advance", etc. Some use the vowel in "calm" others use the vowel in "mat" or "mad". Another regional difference is the pronunciation of 'e' sounds especially followed by 'l', such as "Melbourne", "helped", "cellist", with Victorians generally transposing the 'a' and 'e' vowel sounds in many words. For example, pronouncing an 'e' sound in words such as "alchemy" or "chalice", yet an 'a' vowel sound for "Celery."
