"Explore software architectures and design issues for
speech applications."
Speech technology is increasing in importance as a means for improving
human-computer interfaces. Speech interfaces are being deployed in desktop
environments and applications, in telephony call centers and in small personal
computing devices.
Research Issues
This group is exploring software architectures and design
issues for speech applications and is developing a platform that enables
efficient development and deployment of real-world speech systems by:
- Understanding the potential and the limitations of speech technology
in the human computer interface,
- Enabling efficient development of speech applications on Sun
platforms,
- Working with developers to evaluate our tools and methodologies,
- Supporting the use of speech technology by Sun's product divisions.
Projects
Sphinx-4: An open source speech
recognition system written entirely in the Java TM programming
language. Sphinx-4 is a speaker independent, large vocabulary, continuous
speech recognition system based on the Sphinx family of speech recognizers
developed at Carnegie-Mellon University. The Sphinx-4 project is hosted
at cmusphinx.sourceforge.net.
FreeTTS: An open source speech synthesizer written entirely
in the JavaTM programming language. The synthesizer
is available at freetts.sourceforge.net.
To learn about how FreeTTS performs read the FreeTTS - A
Performance Case Study technical report.
JavaTM Speech API: The Speech Integration
Group led the development of the Java Speech API
in cooperation with Sun's Java Software
division and external partners. The Speech Integration Group developed and
published the following specifications and documents:
SpeechActs: During the period 1993-1997, the Speech Applications
Group, under the leadership of Nicole Yankelovich, researched and developed
SpeechActs, a framework
for developing telephony speech applications with conversational interaction.
This project involved research on both fundamental user interface issues
and speech architectures.
