Vhdl Implementation of Text to Speech Converter for Satellite Radio Receivers

Text to speech (TTS) is synthetic, generated speech. Typed text is converted into speech using various approaches. This project work is about building a Text to Speech converter using a VLSI (Very Large Scale Integration) approach. TTS conversion has numerous applications from enabling Robots to speak, to reading out to the blind. Specialized applications require innovative approaches for efficient user friendly, speech synthesis, rather than using the already developed speech engines. The motivation for this work is drawn from designing of a specialized TTS system to convert E-mail messages, received from a WorldSpace Satellite Radio Receiver to speech which is being undertaken as a value added service facility to the existing Digital Satellite Receivers. The work is implemented in VHDL and downloaded into the XILINX FPGA SPARTAN chip. The entire system is tested for numerous test input. It is observed that the overall feasibility of the TTS conversion has been well implemented incorporating very fast conversion rates.
