I found 11 matches on amizon, with a huge range in prices.
$17.95 to 89.95.
Here is one.
Made for almost any room and lifestyle; this heavy-duty; stylish clock
boasts all the features you could ever ask for in a timepiece - and more.
Its cube-like shape makes it easy to find a place for; be it your kitchen
counter or RV front table. And the features it offers make it an asset to
any room. All the buttons are found on the top of the clock in a circular
pattern. The Talk button is in the center; and gives you all the information
you need to make a plan. "It is 5:49 PM. The temperature is 70.5 degrees
Fahrenheit. The humidity is 47 percent." Right away; you know you're late
for your dinner date; it's too hot for your guests; but the humidity is just
fine. But that's not all. The clock can speak the time in either 12 or
24-hour format. With the press of a single button; you can access the
built-in timer; perfect for makeing sure you don't burn your cookies - or
tonight's roast beef. The clock will even announce how much time is left on
the timer when you hit the Talk button; something no other Talking Timer
will do. This clock is the RV-lover's dream; and the one-stop solution for a
crowded apartment or basement suite. It even has rubber feet to keep it from
sliding around; making it a great choice for even a large kitchen. It's an
alarm clock that speaks the time and temperature; has a built-in timer; and
can even announce the humidity! Takes 4 AAA batteries; not included.

Does anyone know if the talking clock that I think is called the cube  is 
still made?  about three inches in all directions as a cube.  Static 
electricity took one of mine out.  Thanks.
