I use it to transcribe voice messages that come in through our PBX. The PBX sends the voicemail mp3 to Watson, it sends back the transcription along with a guess (%) on how accurate it is (then the PBX emails the transcript attempt and voicemail attachment to whoever). It's almost always good enough to know what the message is about, sometimes perfect, often hilarious.

Does it return a confidence % for the whole transcription or does it rate each word/phrase?

The PBX usually chunks the send, Watson returns a % for each chunk it processes and then the overall average upon completion.
