Software Automatic Mouth, or S.A.M. (sometimes abbreviated as SAM), is a speech synthesis program developed by Mark Barton and sold by Don't Ask Software. The program was released for the Atari 8-bit computers, Apple II, and Commodore 64. Released in 1982, it was one of the first commercial all-software voice-synthesis programs.{{Citation needed|date=December 2019}}
Don't Ask Software also sold PokerSAM, a poker game with speech,{{cite web |title=PokerSAM |url=http://www.atarimania.com/game-atari-400-800-xl-xe-pokersam_4036.html |website=Atari Mania}} and also licensed out the S.A.M. engine for use with other games, such as Tales of the Arabian Nights for the Commodore 64.
Technology
The Apple version uses an included expansion card which contains an 8-bit DAC, although hackers created a modified version of S.A.M. which can instead use the computer's one-bit audio output (with the addition of much distortion) if the card is not present.{{Citation needed|date=December 2019}} The Atari version makes use of the embedded POKEY audio chip. Speech playback on the Atari normally disables interrupt requests and shuts down the ANTIC chip during vocal output. The audible output is extremely distorted speech when graphic and text display is turned on. The Commodore 64 makes use of the 64's embedded SID audio chip's 4-bit volume DAC, reducing its quality significantly vs the Apple and Atari versions.{{Citation needed|date=December 2019}} When producing speech, the Commodore 64 version blanks the screen as the program accesses memory, although a "light" mode can be activated that leaves the screen active, producing a "gravelly" voice. Active sprites also cause a deterioration in the quality of voice output.{{ cite magazine | url=https://archive.org/details/mag_PersonalComputerNews063-02Jun1984/page/n37/mode/1up | title=SAM speaks out | magazine=Personal Computer News | last1=Conway | first1=Barbara | date=2 June 1984 | access-date=20 December 2024 | pages=36 }}
Legacy
S.A.M. was used as the basis for the original MacInTalk speech synthesis software.
The technology was recreated for the voice of the character of "SAM" in the software Chipspeech.[https://twitter.com/chipspeech/status/885160064402763776 link]
