RECAIUS™ speech synthesis technology

Improves naturalness and speaker similarity of synthesized voice using a speech synthesis method based on statistical parameter selection.

  • Achieves smooth and natural synthetic speech by introducing new acoustic feature parameters enabling precise reproduction of the speech waveform shape and through our original speech synthesis method that combines a processing to select acoustic feature parameters from among huge numbers of candidates with a statistical parameter generation method. This enables speech synthesis with dramatically improved quality and better reproduction of the texture of the voice.


  • Reproduce the voices of past voice actors and characters (reproduce speaker characteristics).
  • Natural synthetic speech for spoken language (speeches for announcement or translation)
