Revisiting Over-Smoothness in Text to Speech

Audio Samples

All of the audio samples use Parallel WaveGAN (PWG) as vocoder.

Audio Samples for Table 2

Audio Samples for different methods for simplifying data distributions for TTS.

  • This type was introduced into England by Wynkyn de Worde, Caxtons successor.
GT GT (PWG) MAE
FreqAR TimeAR FastSpeech 2
  • Most of Caxtons own types are of an earlier character, though they also much resemble Flemish or Cologne letter.

  • The worst, which perhaps was the English, was a terrible falling off from the work of the earlier presses.

Audio Samples for Table 6

  • I thought of these things last monday, and definitely renounced the idea of becoming a grocer; and as i wandered round the bookstall, thinking, i came across a little book, sixpence in cloth, a shilling in leather, called proverbs and maxims.

  • She had clasped the golden pillars which supported the altar had turned perhaps her dying looks upon the crucifix; for there, with one arm still wreathed about the altar foot, though in her agony she had turned round upon her face, did the elder sister lie when the magistrates first broke open the street door.
