Speech Output - PIC Control

[ajt]

I searched this board on this topic and was suprised to find nothing.

I am considering a project that needs a speech synthesizer output. Has anyone done a PIC based design like this who can give me some ideas to get started (and what pitfalls to watch out for)? Links to other articles on the topic would also be appeciated. Thanks

Al

Have a look at the CCS examples - there is one for voice using another chip. ex_voice

I really *did* do some searching! [G] ... and the information was right under my nose... Thanks.

The example identified a potential part (ISD400x) which led to a lot of information and source code on using it with a PIC. I have a Text-to-Speech application and am not sure how I can apply this part to that but am delving into it now.

Hi Al,
I have posted an operations manual and schematics of a project using a PIC processor and the ISD speech chip. It may not be exactly what you need to design, but it may give you some ideas!
I have included the link for the download in this message.

Thanks!

That's a very nice looking board.

I'm trying to get going on a Text-To-Speech project where I can't easily use pre-recorded messages. In my application, times between events are measured by the processor and the segment name and time is to be "spoken". e.g. "Segment 2, 7.15".

I've found some integrated T-T-S processors (e.g. WTS701 from WinBond) that are a bit pricey in small quantities but would do the job nicely. I'm wondering how a part such as the ISD device could be used to "dictate" fractional numbers. I guess I could pre-record "Segment", the 0-9 digits, the "point" and some dead air for pauses and do it but am worried the speech would be too robotic sounding. OTOH, I may be assuming too much in the higher end T-T-S processors as putting inflections, etc. into the pronounciation.
