A single chip solution for text-to-speech synthesis

A single chip solution for text-to-speech synthesis is presented in this paper. The proposed system is the first hardware solution for synthesizing unlimited vocabulary speech in real time for Turkish language. The integrated circuit converts incoming letters in ASCII format to speech by using clues from the textual context. The system has a language dependent database, which contains pre-recorded human speech samples coded by LPC (linear predictive coding) method. It has a very low complexity (consisting of only 3503 technology specific cells) compared to other board-level designs available in the market, resulting in low power and flexibility for FPGA implementation or incorporation into larger chips as IP.
