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 read out stock prices and stock-price changes from a live data broadcast. Using this receiver, listeners can access their chosen stock information at any time and at an appropriate speech rate. We also propose a high-quality voice synthesizer for use with this receiver. A subjective evaluation confirmed the superiority of this voice synthesizer over commercially available ones.
