Towards Personalised Synthesised Voices for Individuals with Vocal Disabilities: Voice Banking and Reconstruction
نویسندگان
چکیده
When individuals lose the ability to produce their own speech, due to degenerative diseases such as motor neurone disease (MND) or Parkinson’s, they lose not only a functional means of communication but also a display of their individual and group identity. In order to build personalized synthetic voices, attempts have been made to capture the voice before it is lost, using a process known as voice banking. But, for some patients, the speech deterioration frequently coincides or quickly follows diagnosis. Using HMM-based speech synthesis, it is now possible to build personalized synthetic voices with minimal data recordings and even disordered speech. The power of this approach is that it is possible to use the patient’s recordings to adapt existing voice models pre-trained on many speakers. When the speech has begun to deteriorate, the adapted voice model can be further modified in order to compensate for the disordered characteristics found in the patient’s speech. The University of Edinburgh has initiated a project for voice banking and reconstruction based on this speech synthesis technology. At the current stage of the project, more than fifteen patients with MND have already been recorded and five of them have been delivered a reconstructed voice. In this paper, we present an overview of the project as well as subjective assessments of the reconstructed voices and feedback from patients and their families.

متن کاملImmediate effects of vocal warm-up exercises on elementary teachers' voice
Introduction: Teachers are a large group of professional voice users who are exposed to many voice problems. Vocal warm-up exercises (VWUE) can prepare the muscles involved in vocalization before teaching and can reduce voice damage in teachers. However, limited studies have examined the effects of VWUE on teachers' voices. Therefore, the present study was conducted to investigate the immediate...

متن کاملBuilding personalised synthetic voices for individuals with severe speech impairment
For individuals with severe speech impairment accurate spoken communication can be difficult and require considerable effort. Some may choose to use a voice output communication aid (or VOCA) to support their spoken communication needs. A VOCA typically takes input from the user through a keyboard or switch-based interface and produces spoken output using either synthesised or recorded speech. ...
