Medical testing device and associated method

摘要

A medical testing device comprises an analog-to-digital converter for converting to an electrical digital signal a voice-frequency signal originating in a speech by a human speaker. The A/D converter is connected to a speech analyzing circuit which analyzes the digital signal to determine a value for a preselected first parameter characteristic of the speech, the parameter being taken from the group comprising frequency or tone, amplitude or loudness, and speed. A video camera or other component is provided for generating a video signal encoding an image of the human speaker's face during the speech. The camera is connected to an image analyzing circuit which processes the video signal to determine a value for a preselected second parameter characteristic of an emotional expression of the human speaker during the speech. A text encoder is provided for encoding a text corresponding in essential words to the speech. A correlation circuit is operatively connected to the speech analyzing circuit, the image analyzing circuit, and the text encoder for correlating values of the first parameter and the second parameter with words of the text.
