In 1968, the first truly portable talking clock, the Mattel-a-Time Talking Clock, was released. This clock used a record, needle, and tone arm to produce its sound. In 1954, Ted Duncan, Inc., released the Hickory Dickory Clock, a crank toy intended for children. 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. London began a similar service three years later. On its first day, February 14, 1933, more than 140,000 calls were received. In 1933, the first practical use of talking clocks was seen when Ernest Esclangon created a talking telephone time service in Paris, France. However, these belts were often broken by the hand-tightening required, and all attempts to reproduce the celluloid ribbon have so far failed. It is on display at the National Watch and Clock Museum in Columbia, Pennsylvania.Īlthough 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. 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). Lambert used lead in place of Edison's soft tinfoil. Around 1878, Frank Lambert invented a machine that used a voice recorded on a lead cylinder to call out the hours. Soon after Thomas Edison's invention of the phonograph, the earliest attempts to make a clock that incorporated a voice were made. It may present the time solely as sounds, such as a phone-based time service (see " Speaking clock") or a clock for the visually impaired, or may have a sound feature in addition to an analog or digital face.Īlthough 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.
