Index Number: 10831 [This is from the Blink Talk Conference] well, I was thinking of something like that. I have heard of a card that you can get for around $250, or so, that allows you to digitize voice, and save it to hard disk. Takes a lot of space to sttore voice, depending upon sampling rate. Since we're dealing with phone lines, the sampling rate would not have to be more than, let's say 10 kilohertz, or so. Not sure what those cards sample at, though. think they might be for music, or something. No reason yu couldn't digitize voice, then upload it to a board for future download, or something. Now, wouldn't that be neat!!?? Only problem is that a person would need 100 megs of drive space to get 15 to 20 minutes of digitized speech on there, I think. Great idea, though, Dan! Hope to hear from you very soonn Dave Martin -- Uucp: ..!{decvax,oliveb}!bunker!hcap!hnews!106!800!Dave.Martin Internet: Dave.Martin@f800.n106.z1.fidonet.org

I run a service called NEWSLINE for the Blind. We use volunteers to read virtually the entire Albuquerque Journal each day. Their voices are digitized and stored on hard disk. Listeners call in using a touch tone phone and retrieve the parts of the paper they want. They can choose what categories they want, skip or skim or read each story. We use digitizing boards from Dialogic Corp. My guess is that they are digitizing from Khz 8 to Khz10 of voice. It is good phone quality. The digitization process consumes 3K of disk space per second. This works out to ten magabytes an hour. The boards also automatically compress the data, so without this compression, the files would be even larger. David Andrews ...
