Method and device for recognizing speech triggers speech-controlled procedures by recognizing specific keywords in detected speech signals from the results of a prosodic examination or intonation analysis of the keywords.

摘要

A speech identifier has functional blocks like feature analysis (1) and keyword recognition (2). The results of the feature analysis are fed to a function block for intonation evaluation (4) consisting of a standard base frequency analyser. A keyword identifier's output connects to a keyword memory (3) for passing to function blocks performing context examination (5) and verification (6) that leads to the issue of a command.
