[athen] recording lectures via mp3 players for use on web

I took a trip out to Halifax to see the Liberated Learning concept in action
some time ago. The technology is promising but the cost is quite high.
These were costs associated with licensing the software and support. The
local equipment costs are separate.

SecurityNow podcast site is an excellent example of what can be done with
very little cost for lectures/events.

I echo Dan's recommendation regarding the podcast and add my own suggestion
that we also listen to the "this week in tech" podcast. While more amusing
than informative, this podcast does have some excellent analysis.

Please let me know if I can provide further information.

Hi Nick;

Check out Liberated Learning (www.liberatedlearning.com). It's based at
St. Mary's University in Nova Scotia. They are using IBM Products (Via
Voice among others) to convert spoken lectures to digital format and are
willing to partner with other universities.

I am quite concerned, along with many of you, about the accessibility of
podcasts. MIT is exploring the use of iTunes to distribute files of
on-campus events, both audio and video. I am quite concerned about the
lack of accessibility of the audio and video to deaf/hoh people as well as
concerned about the inaccessibility of iTunes itself as a program. In
addition, some iTunes files are of a proprietary format (AAC) that cannot
be played on other, more accessible podcasting software or players.

An MIT professor, Jim Glass, is conducting research to convert audio files
into digitized text via speech recognition technology and we are hoping
that may prove to be a useful tool in the conversion from spoken word to
digitized and searchable text. Someone also mentioned a company called
Podzinger (www.podzinger.com) which uses speech recognition technology to
convert podcasts to digitized format and make them searchable.

I'd enjoy talking more about this issue and exchanging information with
others who are also interested.
