This MATLAB exercise compares word concatenation synthesis versus naturally spoken utterances Sentence 1: this shirt is red. Sentence 2: are you a good boy or a bad boy. The sources files can be found in I drive. (a) Concatenate the four words for sentence one and play the sequence of concatenated words along with the natural sentence. What is the ratio of durations of the concatenated word sentence and the natural sentence? (b) Repeat part (a) for the words of sentence 2. (c) Create a pair of wideband spectrograms of sentences 1 on a single figure with the natural speech spectrogram at the top and the concatenated speech spectrogram at the bottom.
