That requires that each sound is replaced with a letter.
There are more sounds than letters AFAIK. http://w3.inf.fu-berlin.de/lehre/SS05/efs/materials/PhonSymb...

Also, you can combine letters - e.g. keep "naive" the same, but write "fayv" instead of "faiv" for "five" to indicate a diphthong. And keep "ship" the same, but write "shiip" for "sheep" to indicate a long "i" sound.
A better example of a phoneme in English is the aspirated and non-aspirated [p] sound (transcribed as [pʰ] for aspirated). It's just the difference between holding in a bunch of air and pushing it out, and most English people can't hear a difference.
Edit: I may have been confused, were you just pointing these out as being all different phonemes?
