- That's a tough one. Yes, there are hardware speech synthesizers which would
- work just fine on a Unix box, but that's not really how one usually goes
- about getting Unix to talk.
- The easiest way to do that is to get a MSDOS machine and outfit it with
- a speech synthesizer, a telecommunications program such as "kermit," "Procomm,"
- or something similar, and a TSR software program whose purpose it is to
- make the screen display usable for speech. You, then, connect a serial port
- on the Unix system to a serial port on the PC and cause the PC to behave
- like a VTxx terminal. To put a speech synthesizer directly on a Unix box
- would be a real trick, especially for a beginner. It is definitely a
- possibility, but it would require the creation of a psudo terminal and device
- driver for that purpose. Why bother when the PC method is more straight-
- forward.

-
- This is a perfectly good question, but, again, there is no easy
- answer. Most of the action in the area of OCR for the purpose of allowing
- blind people to "read" a book seems to be with MSDOS machines. OCR is very
- CPU intensive so what you really want is the fastest box you can get your
- hands on. If the software is smart enough to take advantage of all available
- ram, then you want to do as much with RAM as possible since that is the
- fastest way to access data. There is a fairly decent speech synthesizer
- called the Echo which presently sells for less than $200.00, but one can also
- buy a gold-plated marval for several thousand Dollars. You just need to ask
- yourself whether it is worth all that for the somewhat better speech quality.
- As for the computer, itself, both it and the scanner are items which
- can be shopped for just like any other equipment purchase. One can probably
- do pretty well for $5,000.00, give or take a little.
- Be careful. It is easy to spend tons of money and end up with absolutely
- nothing.

-
- A very good thought. Unix does loads of wonderful things, but I
- don't think it is the answer, here. The only thing that a Macintosh provides
- is an audio output channel which can use DSP to create speech and other
- high-quality sounds without external hardware. One can get a card like the
- Sound Blaster for a PC which can do the same type of thing, but I like the
- external hardware approach because it does not use CPU resources as hungrily
- as does the use of the host system to actually generate the speech.
- Finally, I am only taking up newsgroup space for this reply because
- these questions come up more often than one might think. There is a Usenet
- group called misc.handicap which is a better forum in which to discuss the
- pros and cons of various access methods, but still, the computing community
- needs to be aware that there are reasonable solutions to these problems but
- the problem is in figuring out exactly what is most suitable for a given
- individual. What do I use? I use a PC/XT both at home and at work. I
- would just about give my right thumb for a good OCR system, so I am not
- defending PC's due to the fact that that is what I just bought. I have seenm
- PC-based systems which really zipped along and they are simply easier for a
- blind person to use since they don't require a graphical interface for
- everything.
