Ex_Voice.c problem

I'm just wondering if anyone has successfully used the ex_voice.c program in the examples included with the compiler software. I am attempting to build a robotic vehicle that will say "Excuse me" or something similar when it bumps into and obstruction.

I am using the ISD4003 chip as described in the example and the PIC16f877A develpment kit. The pin connections required are slightly different than the rough schematic included with the program but I am fairly sure that I have everything connected correctly.

I believe that the problem I am having is with the program itself. When used with Windows HyperTerminal, the program displays the line "This program converts text to speech. Would you like to erase the current dictionary? (Y/N)", waits for about 1 second, and reprints the line again. If I can quickly answer the question, the program will then move on and display the line "Enter a sentence for me to speak.....etc". At which point I should be able to enter a string of characters until I press ENTER but the program only allows me to enter one character and then it returns to asking me if I wish to erase the current dictionary.

The scrolling of the initial question does not occur if I use the monitor window within the debugger but it still does not allow me to enter more than one character after the "Enter a sentence" statement.

I would like to use HyperTerminal because this is the program with which I am controlling my vehicle but any other suggestions would be welcome.

Is this a known problem that anyone has a quick fix for?

Sorry for the delay in my response folks.

This is for a senior project that is due very soon and part of our original proposal was wireless communication between the robot and a computer. We are having some severe difficulties with the wireless component of the robot.

I have taken my focus off of the voice program, since it was not included in our proposal, to try to solve the communications problem.

I will get back to it soon. I hope.

Thanks for your suggestions so far and I will try to provide more information when I get a chance.
