Hi all

I am after a circuit diagram for a talking clock.
Most appreciated if anyone can help.

Proudly showing off his new apartment to a couple of his friends late
one night the drunk led the way to his bedroom where there was a big
brass gong.

"What's that big brass gong for?" one of the guests asked. "It's not a
gong. It's a talking clock" the drunk replied. A talking clock?
Seriously?" asked his astonished friend.

"Yup" replied the drunk. "How's it work?" the second guest asked,
squinting at it.

"Watch" the man said. He picked up a hammer, gave it an ear shattering
pound and stepped back.
The three stood looking at one another for a moment. Suddenly, someone
on the other side of the wall screamed " You f___ ing asshole....it's
ten past three in the morning!"

I'm not aware of any circuits around for this, except for ones based
on the obsolete SPO256AL2 speech chip. One micro and an SPO256 is all
that would have been needed.
There is no adequate replacement for the SPO256, so you'd either have
to use one of the newer chips (by Winbond I think?), an ISD voice
recorder chip, or a micro with some external memory and prerecorded
words sampled out into a DAC.
I'd go for the ISD or micro solution, as the newer speech chips look
like a pain to use.
Some ISD chips let you record and play back multiple messages.

Dave :)

I have sp0256-als available at my site www.speechchips.com

You can do this with a single microcontroller. An MSP430F149 has 60k of
code space. A real Time clock program needs less than 2k, depending on
how many bells and whistles you need. Assume the worst. For a clock you
need the words:-

zero or ought, one, two, three, four, five, six, seven, eight, nine,
ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen,
eighteen, nineteen, twenty, thirty, forty, fifty, am, pm,

26 words in total, at an average of, say 0.6 seconds per word. OR about
16 seconds worth of speech. The MSP430 can record very high quality
speech at 2500 bytes per second, equivalent to 2.5 bit ADPCM, but far
higher quality. requiring 40k of memory for the calculated 16 seconds of
speech. I estimate that even a well endowed clock, with lots of features
would require less than 4 k of code, leaving about 56k for speech storage.

Of course you could carve the speech up , get rid of many syllables, for
example four + teen, eight + teen, six + teen. Would save 7 long words
and substitute 2 short ones (fif and teen), You could get picky and do
the same with 'ty' on twenty, thrity etc, but you don't really need to.

Output via pwm and an R/C filter.

Alternatively the newer MSP430F169 has a DAC for direct output to a
small audio amp like the LM386.

However you do it you're going to need a micro, either to control the
external speech chip, or to impleemnt my suggestion. Since that is the
case the Evaluation board from Softbaugh for the MSP430F169 has built in
microphone and speaker, schematics provided, so that would allow you to
develop the application directly.
