Ever since OS X 10.2, Apple has included a very good tool to help developers refine the speech synthesis for any word.
The idea is that you may sometime want to have a word pronounced in a slightly different way that OS X regularly does. Maybe, simply have it sound more natural -perhaps even with a particular accent?
This tool is Repeat After Me. Basically, you record a word and the application generates what Apple calls “tuned format”. This code, which is very hard to generate otherwise, gives the speech synthesis engine clues on the intonation and prosody of the word. So you just include the tuned format when you’re writing your application and the word will be pronounced a lot closer to what you had in mind, than if Vicky had pronounced it the way she usually does.
Repeat After Me allows you to adjust the pitch and duration of the phonemes to be pronounced, allowing you to have a much more natural-sounding synthesis.
