Talking clock
A talking clock (also called a speaking clock and an auditory clock) is a timekeeping device that presents the time as sounds. 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.
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.[citation needed] 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 1979, Sharp released the world's first quartz-based talking clock, the Talking Time CT-660E (German version CT-660G). Its silver transistor-radio-like case contained complex LSI circuitry with 3 SMD ICs (likely clock CPU, speech CPU and sound IC), producing a Speak&Spell-like synthetic voice. At the front rim was a small LCD. The alarm spoke the time and also had a melody "Boccherini's Minuet"; after 5 minutes the alarm repeated with the words "Please hurry!". It also had stopwatch and countdown timer modes. The tiny controls to turn off alarm or set functions are hard to reach under a small bottom lid.
In 1984, the Hattori Seiko Co. released their famous pyramid-shaped talking clock, the Pyramid Talk. As a futuristic design object even its LCD was hidden at the bottom, requiring the user to push the clock's top to hear it talk.
