Introduction The aim of text-to-speech (TTS) synthesis is to convert a given text into a speech waveform. For many years, the state-of-the art technique for synthesizing natural sounding speech was to select and concatenate short speech segments WebSpeech coding can be generally divided into waveform coding and analysis-by-synthesis (ABS) methods. In the waveform coding method, each sample value of rebuilt speech signal should be close to the sample value of original signal s ( n) [37–39]373839. Let (1.1) where e ( n) stands for quantization error or reconstruction error.
