INVEST: an expert system for financial investments

A description is given of INVEST, an expert system developed to help make financial decisions. In dialogues with bank officials, INVEST obtains information about a customer's wishes and attempts to make useful and well-founded investment proposals. INVEST is being written as an application of an expert system shell, DONALD, specially developed for this purpose. DONALD is a frame-based system using frame matching as its principal inference mechanism. The inference method and representation of objects as frames are examined in detail, and a brief description of DONALD is given. >

Speech technology and its applications: A technical overview

The first stage of capturing a speech signal is to change it from an acoustic signal into an electrical signal, using microphone and amplifier. This signal must be digitized before the computer can handle it, using sampling techniques. Speech is produced by capturing human speech patterns and analysing them for later reproduction by mechanical means. Text-to-speech synthesis is used in driving voice synthesizers. Speech recognition is based on the matching of frames of speech. Dynamic programming is a significant step forward in speech recognition. An application is currently being developed using speech recognition on a PABX.
