Try Wavepad.
Use the transcript editor tool. Within WavePad, you can open any audio or video clip that has audio, go to the Voice tab, and click the Transcript Editor button. This tool will generate a transcript of the audio, dividing it into phrases that you can view, edit, and manipulate within the program.
The feature uses speech recognition to create the transcript and allows interaction with the text for editing and navigation.
