ABSTRACT:
The allophonic text-to-speech generator (ATTG) 10 includes a CPU 100. The CPU has a random access memory 102 and a read only memory 104 for holding the operating system, application programs, and data for the CPU 100. A keyboard 110 provides a user with control over the CPU 100. A database 130 holds phonetic transcritps of words. Such databases are well-known in the field of telephone directory assistance. A second database 140 maps allophonic text to parse and pre-recorded allophones. The CPU 100 converts a phonetic transcript of a word into an allophonic text string in accordance with a rules program 120. Then the CPU 100 extracts the audio allophone files of the allophonic string and concatenates the audio files to form the new word in the same voice as the other words fromed from the allophones in database 140.
