A Machine that Can Hear and Talk Is the Current Goal of Speech Recognition Research Efforts

Article Abstract:

Researchers at PA Technology, a technology and management consulting firm, are currently developing an all-hearing, all-speaking computer system. Speech processing technology is divided into three categories. The first, speech recognition, is the ability of a machine to recognize what is said or who is saying it. Problems arise with the variability of human speech. Speech synthesis, the second catagory, is the machine's ability to talk back. Reseach is being done to create sounds which are realistic and natural. The final category is speech encoding, or the translation of analog speech into digital form for storage and transmission. This is a low-cost means of communicating between people. A photograph shows an acoustic testing facility.

Texas Instruments' Speech Software Addresses the Limitations of Voice Synthesis Technologies

Article Abstract:

Synthesized voice, created by analyzing sound and converting it into digital form for storing, takes a large amount of memory. Speech can also be synthesized through complex rules for producing words from text. Texas Instruments is offering the Speech Command package, used with the TMS 320 digital signal processor on the TI Professional Computer, to provide voice input and feedback without the memory problem. Wang Laboratories' Speech Plus, which converts ASCII characters into speech on the Prose 200 converter can be used for database inquiry, voice mail, and proofreading. Hewlett-Packard's compact Speech Output Module, with an RS 232 port, consists of a mathematical model of a voice tract and pre-recorded vocabulary for prompting.
