13. The system of claim 12 , wherein the instructions that, when executed, further perform steps comprising: segmenting the audio data into a plurality of time segments; transforming each of the time segments into first bins representing the first amplitude data as a function of frequency; and comparing the first bins of each time segment to second bins representing the second amplitude data, wherein the second amplitude data corresponds to positively identified occurrences of the at least one spoken word sound, or portions thereof, spoken over various non-spoken word sounds, the training data accessed from a training set database.

The system of claim 13 , wherein the instructions that, when executed, perform steps comprising matching further comprises instructions that, when executed, perform steps comprising: determining a subset of the positively identified occurrences of the at least one spoken word sound to match against the bins of a current one of the time segments, the subset determined based on previously matched time segments occurring earlier in the audio data than the current time segment.
