![]() MacinTalk 3 introduced a great variety of voices. It remained the recommended version for slower machines even after the release of MacinTalk 3 and Pro. 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. 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.

But if you want something that can be used on your smartphone or tablet then download a text to speech app instead.This article's lead section may be too short to adequately summarize the key points. Here is a list of the best text to speech software that you could use. No wonder, TTS and other voice software are becoming more commonly used. Furthermore, TTS is now popular in business environments, as people use it to boost their productivity. And since TTS allows kids to both see and hear text when reading, it creates a multi-sensory reading experience. That is because some kids have a hard time decoding and understanding printed words on pages. If you're not aware, print materials like books and handouts can be an obstacle for kids to learn reading. Nowadays, TTS and related read-aloud tools are being used in an attempt to assists students in their reading comprehension skills. The OCR allows TTS to read text aloud from photos. Moreover, some TTS tools have a technology called optical character recognition (OCR). But, its voice quality varies, with some sounding like a human. The voice in TTS is computer-generated, and its reading speed can be controlled from slow to fast. TTS works with every personal digital device, from computers, smartphones, and tablets. TTS is sometimes called "read aloud" technology.ĭid you know that text to speech systems were first developed to assist the visually impaired? The system provides a computer-generated spoken voice to read the text to the user. All types of text files can be read aloud from Word and Pages documents, as well as web pages. ![]() Text-to-speech (TTS) technology converts digital text to voice output. ![]()
