Clocks. -- "The Phonographic Clock will tell you the hour of the day; call you to lunch; send your lover home at ten, etc.".
Although, talking clocks continued to be described as a possibility in the following decades after Edison identified them in 1878 as highly probable, few clocks actually talked. One exception was Frank Lambert who in 1878 invented a machine that used a voice recorded on a lead cylinder to call out the hours. Lambert used lead in place of Edison's soft tinfoil. According to Wikipedia the next talking clock was until 1910 with Hiller's Speaking Clock (see below).

The Phonogram (May 1900) included an alphabet related to the Phonograph with "C is for CLOCK"
The Phonogram (July 1901) announced a talking alarm clock was being developed in Switzerland that would be very "useful".

A speaking clock or talking clock is a live or recorded human voice service, usually accessed by telephone, that gives the correct time. The first telephone speaking clock service was introduced in France, in association with the Paris Observatory, on 14 February 1933. - Wikipedia

Several toy clocks in the 1950's and 1960's 'talked" by using a miniature phonograph and record inside the toy, however, the 1968 Mattel-a-Time Talking Clock was the first toy that was a talking clock and a working clock.
In the 1970's and 1980's a variety of children's alarm clocks were marketed that kept time and spoke messages using a "record". These talking alarm clocks featured pop culture characters like Howdy Doody, Big Bird, Batman, Charlie Brown, Mickey Mouse -- each, with its respective voice, telling the child that it was time to get up.
In 1979 Sharp released the world's first quartz-based talking clock2 and in the 1990's computer chips replaced records in talking clocks.
The following are a few popular culture examples displaying the fulfilled probabilities for the 'Future' of Edison's Phonograph.
