ADVANCED MEDIA RESEARCH INC — Department of Defense SBIR Phase II: N08-149

Description

The main objective of this project is to develop technologies for variable speaking speed synthesis, or Text-to-Speech (TTS). A TTS system converts written text into spoken language. There are numerous commercial TTS systems; however, most systems do not allow for speed control of the output speech. In the simulation-based virtual training system, TTS systems are used to generate the voice of the virtual role-players. The ability to control the speaking speed of TTS output without sacrificing intelligibility will support a range of fast operational and training scenarios for Aviation Training Systems. Phase I was focused on the feasibility study of developing a variable speed speech synthesis technology. This proposal is a continuous effort toward Phase II, where the main goal is to develop a working prototype to enable realistic and adjustable speed control of synthetic speech that is intelligible enough to support a range of fast pace operational and training scenarios. An additional goal of Phase II is to provide the capability of mimicking the “radio voice” of military personnel, as well as, the capability of generating multiple voices from a single TTS system.
