I have just started learning hiragana, and am confused about the pronunciation of some of them. I have heard some pronunciation guides for け which say it should sound like kay, and some which say it should just be ke (with an e sound like the one found at the start of the English word edge), and some for か say it should be kar, while others are telling me it should be ka (like the a sound at the beginning of apple). Can I have some verification as to which of these is correct, apologies if the question is deemed too basic.
EDIT: Apparently both sets of guides are incorrect, as they try and put the sounds into terms of English pronunciation. This being the case, can someone link me to a guide that explains how to properly pronounce them?
