Base Claim:
1. A method for enhancing the analysis of at least one test word extracted from a test audio source, the method operating within an environment having an acoustic environment, the method comprising the steps of: a first receiving step for receiving on a computing platform at least one training word extracted from a training audio source; a first key phrase extraction step for extracting a training key phrase from the at least one training word according to a linguistic rule; a first feature extraction step for extracting at least one first feature from each of the at least one training word from the environment, or from the acoustic environment; a second receiving step for receiving tagging information relating to a significance level or an importance level of the training key phrase; a key phrase model generation step for generating a key phrase training model based on the training key phrase and the at least one first feature, and the tagging; a third receiving step for receiving at least one test word extracted from a test audio source; a second key phrase extraction step for extracting a test key phrase from the at least one test word according to the linguistic rule; a second feature extraction step for extracting at least one second feature from each of the at least one test key phrase, from the environment, or from the acoustic environment; and applying the key phrase training model on the test key phrase and the at least one second feature, thus obtaining an importance indication for the test key phrase.
