TTS (Text-To-Speech) Technology
After much research and hard work, ECTACO, Inc. is ready to unveil its new Text-To-Speech (TTS) technology for a number of added languages. We invite companies and institutions to learn more about this innovative technology and to make use of it in their hardware and software applications. Interested parties should contact us for more information.
The TTS engine now supports 17 new languages, as outlined below. It allows the pronunciation of any word or phrase written in a format understandable by the system. Initially, only English was used, but the universality of the technology has allowed us to broaden the range of available languages significantly.
The engine is coded in ANSI C, which makes for a high degree of portability to many different platforms. The system can be supplemented with additional dictionaries and can be fine-tuned to any thematic vocabulary.
The engine utilizes formant synthesis at the phoneme and demisyllable level. Sound is generated in three sample rates: 8, 10, and 11 kHz. More technical details are given below.
