Speech Morphing

—Background and Prospective Applications—

Abstract

This article introduces prospective aspects of speech morphing technology in the future of voice therapy and its clinical applications. Speech morphing is based on a new speech analysis, modification and synthesis technology called TANDEM-STRAIGHT. Excitation source analysis procedures used in TANDEM-STRAIGHT are potentially able to handle irregular vocal fold vibration patterns found in voice disorders. Use of the new technology in the form of speech morphing will introduce a new strategy by showing the target voice of therapy or operations well in advance using the patient’s own voice.
