text to phonemes converter

Question

I'm searching for a tool that converts text to phonemes, (like text to speech software) I can program one but it will not be without errors and takes a lot of time!

so my question is:

is there a simple tool for converting e.g. "hello" to "HH AH0 L OW1"

maybe some command-line tool so i can capture the stdout? i'm searching for the phonemes in 'Arpabet' style (see the 'hello' example).

espeak does something like that but the output is not in Arpabet style and the phonemes are not split by some determiner.

Answer 1

If you had searched for Arpabet on wiki you would have found your answer. The CMU guys have prepared scripts which convert most english words to their respective Arpabet phonetic break up.

If you want the phone sequence of a couple of words you can use their interface here. But, if you want it for a big file then you might have to run their scripts on your own. They used to have a working page here, but it seems to be not working now.
