Text to speech
Up until about 2010, there was the analytic approach: This approach uses multiply steps to convert the text to speech. Usually, an input text is transformed into phonetic writing. Thgis says how the words are pronounced, and not how they are writen.In the phonetic writing, phonemes can be identified. The system can then produce speech by putting togethewr prerecorded or synthesized diphones. A problem is to make the language flow sound natural, what linguists call prosody.
