There is no sure way of any two people saying the same word with precisely the same sound.in this respect pronunciation much more closely resembles handwriting than spelling,there are absolute distinctions which can be learnt and imitated with complete precision: one can know
at once whether a word is spelt in a 'standard'way or not. But two persons' handwriting and
pronunciation may both be perfectly intelligible,yet have obvious differences without our
being able to say which is `better` or more `standard.`
