The Intellivoice Voice Synthesis Module was an adapter for the Intellivision, Mattel's home video game console, that utilized a voice synthesizer to generate audible speech. The Intellivoice was a large, brown cartridge that plugged into the Intellivision's side-mounted cartridge slot; games specifically designed for the device could then be inserted into a slot provided on the right-hand side of the module. An International version of the Intellivoice was planned, but never released. The Intellivoice was discontinued in 1983 due to poor sales, with only five titles released with support for the device. == Development History == In the late 1970s and early 1980s General Instrument, like nearly every microelectronics manufacturer, was rolling out their own series of microprocessors and support chips in hopes of gaining a share of the then-new and rapidly exploding market for increasingly sophisticated consumer and industrial electronics. One of the peripheral and support chips introduced for G.I.'s microprocessors was the SP0256 Narrator speech synthesizer chip. Since the Intellivision was already based on General Instrument's CP1610 microprocessor and support chips, and talking electronic products (such as Texas Instruments' Speak & Spell) had already captured the public's fascination, it didn't take long for someone at Mattel Electronics to get the idea that a speech-synthesis module might be an interesting add-on for the console. Engineer Ron Carlson was put in charge of designing a device capable of utilizing the chip. Programmer Ron Surratt was hired to write the software for the module, and Patrick Jost would analyze the voice data for the device.〔(Intellivision Lives Intellivoice Page )〕 The Narrator had 2kB of Read-Only Memory (ROM), and this was utilized to store a database of generic words that could be combined to make phrases in Intellivision games. The words included numbers, "press," "enter," "and," "or," and "Mattel Electronics Presents" in a generic male voice. These phrases (as well as the speech for the first game, ''Space Spartans''), were recorded and digitized by Carlson and Jost at General Instrument's facility in New York, and the resulting data was turned into a mask so that a customized version of the SPO256 could be manufactured with the generic phrases permanently stored inside the chip. Since the Orator chip could also accept speech data from external memory, any additional words or phrases needed for specific games could be stored inside the game cartridge itself. Development of the unit did not go flawlessly, however. According to Ron Surratt, when he first received Carlson & Jost's data from G.I.'s New York facility and loaded it into the prototype unit, all the device would do was repeat "Auk yooo! Auk yooo!" over and over, which didn't exactly impress the Mattel executives and marketing personnel who had come to see the demonstration. This led to several heated phone calls between Hawthorne and New York, and considerable finger-pointing between the hardware and software camps until the problem was found. Once the bugs were ironed out, Mattel Electronics committed themselves to producing voice games and built a state-of-the-art voice lab at their Hawthorne, California facility to do the recording and digitization on site. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Intellivoice」の詳細全文を読む スポンサード リンク
