WORLD: A Vocoder-Based High-Quality Speech Synthesis System for Real-Time Applications

A vocoder-based speech synthesis system, named WORLD, was developed in an effort to improve the sound quality of realtime applications using speech. Speech analysis, manipulation, and synthesis on the basis of vocoders are used in various kinds of speech research. Although several high-quality speech synthesis systems have been developed, real-time processing has been difficult with them becaus...

A real-time speech data analysis system for data processing to support speech synthesis applications

Practical high-quality speech and voice synthesis using fixed frame rate ABS/OLA sinusoidal modeling

This paper describes algorithms developed to apply the Analysis-by-Synthesis/Overlap-Add (ABS/OLA) sinusoidal modeling system to real-time speech and singing voice synthesis. As originally proposed, the ABS/OLA system is limited to unidirectional timescaling, and relies on variable frame length to accomplish time-scale modification. For speech and voice synthesis applications, unidirectional ti...

Real-Time Interfaces for Speech and Singing

This paper introduces a new concept in speech synthesisers by constructing devices and methods by which they can be operated in real-time. Further development of this concept may lead to an improvement in the conversational capabilities of people with ‘speech communicators’. This paper outlines the current limitations of such systems and then describes the methods used to give the user real-tim...

Communication over the Internet Using a 3d Agent with Real-time Facial Expression Analysis, Synthesis and Text to Speech Capabilities

We present a system for Internet communication that enhances traditional text-based chatting with real-time analysis and synthesis of the chat parties’ facial expressions. It is composed of three main modules: a real-time facial expression analysis component, a 3D agent with facial expression synthesis and text-to-speech capabilities – a talking head, and a communication module. So far we have ...
