Use 'transcription buddy' available for free download at www.download.com
It has a free 30 day trial (but if you uninstall it and download it again, it lets you).
It is great because under view>options it has 'variable pauses' so you can set it to for example,
play 15 secs
pause 2 secs
rewind 5secs
So once you have set it up for the speaker's speed (e.g. sometimes, I only get it so it plays 7 secs, pauses 3 and rewinds 5 or something), you never have to press pause, stop or play becasue it continually loops until it reaches the end of the track. It works with most files.
