Ask HN: Can someone recommend a good audio transcription service?

5 pointseserorg8 comments

Can anyone here speak to a positive experience they have had using an online transcription service?

I have a large collection of audio conference recordings that I am trying to get transcribed for internal business use.

I've tried a variety of voice-recognition software, and they just do not work for the level of fidelity that I am dealing with.

Thanks!

So my company http://castingwords.com provides transcription services (based on Amazon's Mechanical Turk). We've been doing this for years and have gotten some excellent reviews for our transcription (not just our technology) including a nice one from the Wall Street Journal - we've got a quote from that on the front page.

Andy Baio used Mechanical Turk. Positive experience.

Sweet!

I'm hacking together a perl script right now using the Mechanical Turk API.

It's automatically spliting up the mp3 files, generating the html forms, and loading them into MTurk.

I'm going to use a 2x coverage for each chunk and see what happens.

This is a brilliant idea. Thank you for the suggestion! I can't believe it didn't occur to me before -- and we are _very_ heavy users of AWS.

We had initially considered using MTurk as the backend for our transcription service. But found it difficult to tailor to the transcription process we had in mind.

The system we use now has multiple stages. We split up the files into smaller chunks which are then picked up by our transcribers. Each transcript is then reviewed, speaker initials and timestamps are added and then they are finally collated.

We've gotten pretty decent results with our system so far with some very satisfied customers.

So CastingWords has obviously made MTurk work and work well, but finding ways to maintain quality levels and consistency has not been an easy process. We've had to give up completely on "quick and dirty" (IE super-cheap) transcription. Instead we focus on a much higher quality product. And maintain quality by using with many many (mainly QA) steps - the shortest, simplest transcript is seen by 14 turkers - and runs through a 7 step process. And with added audio length the pipeline gets even longer.

We have been using the Network Connection transcription services for the last three years and been very satisfied. http://thenetworkconnection.com/transcriptionservices.htm

My girlfriend is a trained court reporter and does freelance transcription on the side. She charges by the audio-hour. Interested in getting in touch?
