This basic scale can be found for less than $50.  This is a talking scale that has all of the features of standard digital bathroom scale.  For instance, it can hold up to 440 pounds, so most people will have no issue with using this scale.  It is accurate within 1 percent of your body weight.  However, what makes this scale stand apart from others is that it is a talking bathroom scale.  The voice can announce your weight in either kilograms (kg) or pounds (lb).  You can turn the voice off if you do not want to use.  There is also a large LED display for those that can read the display.  This is the scale I would recommend if you need one with voice announcements.

My Weigh FunWeigh Fun Talking Digital Scale -

Okay, a talking bathroom scale does not just have to be for the visually impaired.  While this scale does help those that cannot see the readout display, it also adds some fun by having joke expressions built in so that when you step on the scale you may hear something like, "Is someone else on here with you?" or "I think you just broke me".  This can be funny for a while, but there only 8 different phrases so you will probably get used to them after a couple weeks.  However, this talking bathroom scale still does the job you want it to do so if you think that the joke expressions may help brighten the beginning of your day I would suggest this scale.

One important function that all of these scales include is the ability to turn off the voice feature.  There may be times when you want to weigh yourself but not announce your weight to everyone within hearing distance.
