Walt the atomic talking clock is very accurate and it's voice is soft with a slight brittish accent. independent living aids has it along with irti etc. I got a couple of talking cube clocks which are quartz have a male voice with a boston accent, a talking calendar and a countdown timer and a beeping alarm. I also have a couple of 24-hour clocks I bought from the nfb materials center whose voice reminds me of a dear friend of ours I just wish it could replicate her voice exactly because it sure is sexy.
