It supports any Macintosh running System Software 6.0.7 or later. Hughes and Marvin voicesĮventually, Apple released a supported speech synthesis system, called MacinTalk 2. Input to the synthesizer can be controlled explicitly using a special phoneme alphabet. The volume, pitch and rate of the speech can be configured as well, allowing for singing. There are various control sequences that can be used to fine-tune the intonation and rhythm. American English and Spanish versions have been available, but since the advent of Mac OS X, Apple has shipped only American English voices, relying on third-party suppliers such as Acapela Group to supply voices for other languages (in OS X 10.7, Apple licensed a lot of third-party voices and made them available for download within the Speech control panel).Īn application programming interface known as the Speech Manager enables third-party developers to use speech synthesis in their applications. Compared to other methods of synthesizing speech, it is not very resource-intensive, but limits how natural the speech synthesis can be. Software Speech synthesis Technology Īpple's text-to-speech uses diphones. Apple later introduced a dictation feature in OS X 10.8 Mountain Lion that sent audio data to Apple servers for processing.Īpple also produced two microphones under the "Apple PlainTalk Microphone" product name, designed to either sit on the side of a CRT display or on top of the screen. However, early speech recognition was voice-command oriented only, not intended for dictation, and was not part of the default system install prior to Mac OS X. Speech recognition, part of the PlainTalk package, was originally available for all PowerPC Macintoshes and AV 68k machines. Siri was introduced as a System Voice in macOS Catalina 10.15, and gender references to all voices were removed in macOS Big Sur 11.3 update. The software has evolved over time, with Mac OS X 10.7 Lion introducing additional accents and languages, and features such as allowing selected text to be read out with a key combination. Since the advent of Mac OS X, Apple has used American English voices for the system, with third-party suppliers providing other languages. MacinTalk, the initial text-to-speech engine, was used in the 1984 Macintosh introduction, while later versions like MacinTalk 2, 3 and Pro introduced a variety of voices with differing requirements for processing power and memory. The text-to-speech technology uses a method known as diphones, which is less resource-intensive but results in less natural speech synthesis. It was made a standard system component in System 7.1.2, and has since been shipped on all PowerPC and some 68k Macintoshes. The result was "PlainTalk", released with the AV models in the Macintosh Quadra series from 1993. In 1990, Apple invested a lot of work and money in speech recognition technology, hiring many researchers in the field. PlainTalk is the collective name for several speech synthesis ( MacinTalk) and speech recognition technologies developed by Apple Inc.
