The second operating system with advanced speech synthesis capabilities was , introduced in 1985. The voice synthesis was licensed by from a third-party software house (Don't Ask Software, now Softvoice, Inc.) and it featured a complete system of voice emulation, with both male and female voices and "stress" indicator markers, made possible by advanced features of the hardware audio . It was divided into a narrator device and a translator library. Amiga featured a text-to-speech translator. AmigaOS considered speech synthesis a virtual hardware device, so the user could even redirect console output to it. Some Amiga programs, such as word processors, made extensive use of the speech system.

This was one of thefirst uses of intelligibility tests to diagnose problems withspeech synthesis.

refers to computational techniques for synthesizing speech based on models of the human and the articulation processes occurring there. The first articulatory synthesizer regularly used for laboratory experiments was developed at in the mid-1970s by , Tom Baer, and Paul Mermelstein. This synthesizer, known as ASY, was based on vocal tract models developed at in the 1960s and 1970s by Paul Mermelstein, Cecil Coker, and colleagues.

Speech synthesis has long been a vital tool and its application in this area is significant and widespread. It allows environmental barriers to be removed for people with a wide range of disabilities. The longest application has been in the use of for people with , but text-to-speech systems are now commonly used by people with and other reading difficulties as well as by pre-literate youngsters. They are also frequently employed to aid those with severe usually through a dedicated .

The goal was a completely simulated text-to-speech system.

Speech synthesis systems use two basic approaches to determine the pronunciation of a word based on its spelling, a process which is often called text-to-phoneme or grapheme-to-phoneme conversion ( is the term used by linguists to describe distinctive sounds in a language). The simplest approach to text-to-phoneme conversion is the dictionary-based approach, where a large dictionary containing all the words of a language and their correct pronunciations is stored by the program. Determining the correct pronunciation of each word is a matter of looking up each word in the dictionary and replacing the spelling with the pronunciation specified in the dictionary. The other approach is rule-based, in which pronunciation rules are applied to words to determine their pronunciations based on their spellings. This is similar to the "sounding out", or , approach to learning reading.

The objective of this project is to develop aspeaker-adaptive text to speech synthesis with applications to highquality automatic voice dialogue, personalised voice for thedisabled, broadcast studio voice processing, interpreted telephony,very low bit rate phonetic speech coding, and multimediacommunication.

The first speech system integrated into an was 's in 1984. Since the 1980s Macintosh Computers offered text to speech capabilities through The MacinTalk software. In the early 1990s Apple expanded its capabilities offering system wide text-to-speech support. With the introduction of faster PowerPC-based computers they included higher quality voice sampling. Apple also introduced into its systems which provided a fluid command set. More recently, Apple has added sample-based voices. Starting as a curiosity, the speech system of Apple has evolved into a cutting edge fully-supported program, , for people with vision problems. was included in Mac OS X Tiger and more recently Mac OS X Leopard. The voice shipping with Mac OS X 10.5 ("Leopard") is called "Alex" and features the taking of realistic-sounding breaths between sentences, as well as improved clarity at high read rates. The operating system also includes , a application that converts text to audible speech.

A recent study reported in the journal "Speech Communication" by Amy Drahota and colleagues at the , , reported that listeners to voice recordings could determine, at better than chance levels, whether or not the speaker was smiling. It was suggested that identification of the vocal features which signal emotional content may be used to help make synthesized speech sound more natural.
