National Library Service Plans Next-Gen Audiobooks
The New York Times (as carried here by CNET, registration-free) is reporting on what seems like an overdue update planned by the adminstrators of the National Library Service for the Blind and Physically Handicapped, which -- thanks to a copyright exemption -- can provide audiobooks without paying royalties. The Library Service will switch from 4-track tape players to audio devices based on flash memory. The article does not mention what sort of codec might be chosen, but does mention a couple of reasons (fragility, and diffculty for use by the blind) to not simply use CDs bearing some compressed audio format. The amount of listenable audio that can be squeezed into readily available pocket-sized storage these days is incredible, at least if you consider listenable things like the 32kbps recordings of old radio shows that the Sherlock Holmes Society of London makes available. (I wonder why small hard drives weren't chosen, though; they seem to bear up pretty well.)
the storage requirements are even smaller than you estimate: consider that these would be pure speech files, so a CELP-derived codec would be appropriate.
remember, Speex is intelligable at 6kbps, decent at 8kbps, and functionally excellent at 11 kbps.
Phus. Sysiphus.
Dealing well with blindness requires a certain amount of discipline (I'm not blind, but I have done volunteer reading (finding engineers/scientists who can read engineering/science texts to blind engineers/scientists seems to be a particular problem) and other services for them).
You can just toss a CD on a table or something and find it. A blind person may not be able to do so, so the blind have places for things, and actually put those things in those places so as to always know where to look for them. Otherwise anything simply put down may be effectively "lost."
A flash card in it's place is no harder to find and handle than a CD.
The problem is the handling, not because of the size, but because of the way blind people have to use their fingers as their eyes, to do things like get the CD into the slot/tray, which can (and does) easily result in scratched CDs.
You can fumble around for the flash slot a bit without worrying about losing your data.

Blind users liked good old audio tape, actually. The reason? Insert tape. Play for a bit. Stop. Eject. Reinsert next day - and lo! it carries on from where you left off listening. CDs, for example, reset to track one. Thus they didn't consider books-on-CD (as apposed to audio cassettes) to be 'progress'. Can't think why.
Even though the Archos mp3 players have screens, the open-source personal jukebox software Rockbox recently implemented a Talking Menu system that can announce directories and playlists. It's useful for non-visual operation, and it proving to be a hit with blind users. Rockbox is being ported to some of the iRiver players...
The last time I wrote about this it was marked down as Troll, probably by some iPod-happy blind-person-hating fanboi. If you're reading this then you are a grade A wanker.
