AutoTranscribe

AutoTranscribe makes verbal audio content accessible. Normally all those recordings on your hard drive cannot be indexed and searched as they are impenetrable binary files.

autoTranscribe can monitor your computer and any time a new audio file is detected, it will prompt you to see if you want to have it transcribed. If you do, the file will be transcribed and the textual content stored in a text file next to your audio file. Once the transcription is done, the files can be viewed from the app, but better than that, they can also be searched for by Spotlight and Finder using the content, not the file name.
