ABSTRACT:
A text-to-speech conversion system that includes a first module to convert text into words, a second module to convert words into phonemes, a third module to map phonemes to sound units, and a storage unit to store speech representations for a library of sound units. The first, second, and third modules and the storage unit are implemented within a single integrated circuit to reduce size and cost. The system typically further includes a ROM to store the codes for the modules, a RAM to store the text and intermediate results, a processor to execute the codes for the modules, a control module to direct the operation of the first, second, and third modules. The storage unit may be implemented with a multi-level, non-volatile analog storage array and may be programmed with a new library of speech representations by a programming module.
