Most accurate speech-to-text program

[CrzyCanuck72]

For a class assignment I need to record and transcribe an interview. To save time and effort, are there any speech-to-text programs that are suitable for transcription?

Any suggestions for good freeware/trial programs would be much appreciated

It's a major undertaking.
