Synthesized Speech
SGDs that use synthesized speech apply the phonetic rules of the language to translate the user’s message into voice output (speech synthesis). Users have the freedom to create novel words and messages and are not limited to those that have been pre-recorded on their device by others.
Synthesized SGDs may allow multiple methods of message creation that can be used individually or in combination: messages can be created from letters, words, phrases, sentences, pictures, or symbols. With synthesized speech there is virtually unlimited storage capacity for messages with few demands on memory space.
Synthesized speech engines are available in many languages, and the engine's parameters, such as speech rate, pitch range, gender, stress patterns, pauses, and pronunciation exceptions can be manipulated by the user.

Famous quotes containing the word speech:
“So hills and valleys into singing break;
And though poor stones have neither speech nor tongue,
While active winds and streams both run and speak,
Yet stones are deep in admiration.
Thus praise and prayer here beneath the Sun
Make lesser mornings when the great are done.”
—Henry Vaughan (1622–1695)
