Archival speech recognition...

Following on from idea #14, I did a quick search on speech recognition for archived audio files and found HP Lab's Speechbot. It is currently analysing audio files on the net from various sources with an accuracy as high as 80% (i.e. successful speech recognition).

These kind of accuracies are probably useable, but for analysis of one's own phone calls, the performance would presumably be better (at least for one's own voice). However, with the additional cues offered by meta-data, such as location and who the call was with, overall performance would be enhanced.

Thinking about the call archiving idea, it would be great to be able to extract clips and send them as messages. I'm not sure about the legality of sending clips into the public domain, but I seem to recall that any calls made over a phone network are essentially public (although it is illegal to tap them of course).
