Development of a prototype data-broadcast receiver with a high-quality voice synthesizer

Here we propose a prototype data-broadcast receiver equipped with a voice synthesizer, which can use the stock prices and the stock-price changes from a live data broadcast. Using this receiver, listeners can access their chosen stock information at any time and at a speech rate appropriate to each individual. We also propose a high-quality voice synthesizer for use with this receiver. The results of a subjective evaluation confirmed the superiority of the proposed voice synthesizer compared with commercially available voice synthesizers.
