Vowel length is generally not semantically significant in English. Vowels are lengthened before voiced consonants, for example, and we don’t even think about it. Compare “cab” and “cap”. As noted here, some Hungarian vowels, such as ’a’ and ‘e’ do change sound when lengthened, but some don’t. Those are the ones that are harder to distinguish for speakers of languages like English.
