A speech synthesis system of digit strings with high quality and multi-channel real-time way

Based on the prosodic characteristics of Chinese digit strings and the application of the LMA synthesizer, a new speech synthesis system is introduced in this paper. Using pre-calculating and table-searching methods, the system can produce synthesized speech for digit strings with various lengths in a multi-channel and real time way. Besides the high speed, little speech library (less than 300 Kbytes), high naturalness and clarity are the three other outstanding features of this system. Listening tests andusers' evaluation showed that the perceptual effect of the output from the new system was much close to the original speech.
