Adam Curry and Dave Winer have been talking about audioblogging lately. In search of converting live streaming video presentations to text for an eLearning venture we stumbled upon some technology from Virage (see the VideoLogger product). This technology will convert speech to text in real time and provide a means for indexing the video for later searching and retrieval.
The products from Virage are definitely overkill for an audioblogger. I've dug out some other links that weren't suitable for the eLearning venture but may be suitable for audiobloggers:
BBN Audio Indexer - This might be the speech-to-text audio technology behind the Virage product. They also have something called Rough'n'Ready. Both definitely worth looking at for audioblogging.
Videogram - actually this would be great for videobloggers. There is a free version as well so one could put something up rather quickly I would think. If anyone does, let me know and I'll provide a link here.
VidiTalk - They describe this as a "streaming media messaging system" (whatever that is). This has a video component but also converts speech to text and does language translation.
I'm sure there are a number of other solutions out there as well so if anyone would like to add comments to this post please do so.
I think we'll start seeing some of these types of technologies in action very soon at conferences. Along with the manual conferencebloggers there will be this automatic conferenceblog being generated. Would definitely be useful to the virtual conference attendees that is for sure. I'm sure Scoble would be very interested in all this.
