Abstract
The invention, in its several embodiments, pertains to methods and apparatuses for text to speech synthesis. In embodiments, the method can include obtaining text of a word having a first syllable and a second syllable, providing from a database a first voice recording of the first syllable, providing from the database a second voice recording of the second syllable, combining by a processor the first voice recording and the second voice recording, and transmitting the combination of the first voice recording and the second voice recording over an audio speaker. In embodiments, the apparatus can include a database, an audio speaker and a processor connected to the database and speaker. The processor is capable of performing the steps of generating text of a word having at least a first syllable and a second syllable, obtaining from the database a first voice recording of the first syllable and a second voice recording of the second syllable, combining the first and second voice recordings, and transmitting the combination over the audio speaker.
