History
Although they would not be considered to be speaking, clocks have incorporated noisemakers such as clangs, chimes, gongs, melodies, and the sounds of cuckoos or roosters from almost the beginning of the mechanical clock. Soon after Thomas Edison's invention of the phonograph, the earliest attempts to make a clock that incorporated a voice were made. Around 1878, Frank Lambert 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. In 1992, the Guinness Book of World Records recognized this as the oldest known sound recording that was playable (though that status now rests with a phonautogram of Édouard-Léon Scott de Martinville, recorded in 1857). It is on display at the National Watch and Clock Museum in Columbia, Pennsylvania.
Although there have been rumors that other talking clocks may have been produced afterward, it is not until around 1910 that another talking clock was introduced, when Bernhard Hiller created a clock that used a belt with a recording on it to announce the time. However, these belts were often broken by the hand-tightening required, and all attempts to reproduce the celluloid ribbon have so far failed.
In 1933, the first practical use of talking clocks was seen when Ernest Esclangon created a talking telephone time service in Paris, France. On its first day, February 14, 1933, more than 140,000 calls were received. London began a similar service three years later. This type of talking time service is still around, and more than a million calls per year are received for the NIST's Telephone Time-of-Day Service.
In 1954, Ted Duncan, Inc., released the Hickory Dickory Clock, a crank toy intended for children. This clock used a record, needle, and tone arm to produce its sound.
In 1968, the first truly portable talking clock, the Mattel-a-Time Talking Clock, was released.
In 1984, the Hattori Seiko Co. released the world's first quartz-based talking clock, the Pyramid Talk.
Current talking clocks often include many more features than just giving the time; in these, the ability to speak the time is part of a wide range of voice capabilities, such as reading the weather and other information to the user.

Famous quotes containing the word history:
“In history the great moment is, when the savage is just ceasing to be a savage, with all his hairy Pelasgic strength directed on his opening sense of beauty;—and you have Pericles and Phidias,—and not yet passed over into the Corinthian civility. Everything good in nature and in the world is in that moment of transition, when the swarthy juices still flow plentifully from nature, but their astrigency or acridity is got out by ethics and humanity.”
—Ralph Waldo Emerson (1803–1882)
“The history of progress is written in the blood of men and women who have dared to espouse an unpopular cause, as, for instance, the black man’s right to his body, or woman’s right to her soul.”
—Emma Goldman (1869–1940)
“We are told that men protect us; that they are generous, even chivalric in their protection. Gentlemen, if your protectors were women, and they took all your property and your children, and paid you half as much for your work, though as well or better done than your own, would you think much of the chivalry which permitted you to sit in street-cars and picked up your pocket- handkerchief?”
—Mary B. Clay, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 3, by Susan B. Anthony and Ida Husted Harper (1902)
