Re: [CODE4LIB] audio transcription software
I've had modest success with "MacSpeech Dictate". It uses the same engine as Dragon Naturally Speaking, but has none of the canned read-back training that Dragon requires. I've been testing it with good quality recordings of our local veterans.(already in digital format on CD) The process I've had most success with is to let MacSpeech Dictate take a run of about 10 minutes, then go back and correct the resulting transcript. Next I re-assign the transcript as the "learning" text that MacSpeech Dictate uses as it re-listens to the same 10 minute segment of the veteran recording. After this initial run, the accuraccy climbs from the starting 50-60%, up to about 80-85% ... still not perfect, but *good enough* to generate text for indexing and keyword searching. If the transcript is going to be exposed/public facing rather than just machine use, then my next step would be to assign the audio file and MacSpeech Dictate transcript to a volunteer/student for final edits... but at least the starting transcript for human editing would be well along the way.

It's not great. In my experience, it gets some words right.

Re: [CODE4LIB] audio transcription software
I'm embarking on exactly the same thing, and for films as well. Depending on the fidelity of your recording you will get different results using Premier Pro in the Adobe Creative Suite 4/5. For modern (2009 recordings) high-fidelity audio we only got 80% accuracy. Dragon still does not work in Keith's scenario. Dragon works ok if you are echoing recorded speech, that is if you repeat the recording using your voice. The production rate is a little bit better than that of a novice typer, so if you have an army of students you might make some headway. I vowed never to attempt this again after echoing a 60 minute film. In the end we are outsourcing the bulk of our transcriptioning.

About a week ago, I stuck my hand between two with large grouchy dogs rendering my hand and wrist useless. So I downloaded the free voice recognition software that can be downloaded for Windows XP and is built into Windows 7 since my hand and wrist still hurt like heck. I spent about an hour training it, and my conclusion is that it sucks but it is better than typing one handed, so I am still using it (including to type this message). Download SpeechSDK51.exe from the Microsoft Speech SDK 5.1 if you're interested. It's totally free and worth every penny. kyle
Re: [CODE4LIB] audio transcription software
depending on your budget there are quite a few services available to do it for you. some include time-code information depending on what interfaces you want to build. came across this list in someone's delicious feed on here: http://www.uiaccess.com/transcripts/transcript_services.html eby On Wed, May 12, 2010 at 2:18 PM, Eric Lease Morgan wrote: > Does anybody here use or know of any audio transcription software? > > We have a growing number of projects here at Notre Dame that include oral > histories.

Re: [CODE4LIB] audio transcription software
youtube actually does this automatically (but only in english). but i'm not going to lie, it sucks. however maybe that's just my voice since i'm always stuffed up.

A great quality service is http://on-sitemedia.com/. I have no idea what she charges.

Re: [CODE4LIB] audio transcription software
Not software, exactly, but this seems like an ideal thing to set up in Mechanical Turk.

Re: [CODE4LIB] audio transcription software
Do you mean software to aid a human transcriber, or do you mean software that can actually use voice recognition to turn audio to text all automated? I am curious if there's anything in the latter quality actually good enough for "oral histories" with their possibly various voices and qualities. Last I looked there was not, but technology advances. Eric Lease Morgan wrote: Does anybody here use or know of any audio transcription software?
