Desired signal spotting in noisy, flawed environments

An apparatus for desired signal spotting in noisy, flawed environments comprising:

• a first identifier unit to identify the desired signal to be spotted and a pool of call samples, wherein the signal is one or more spoken terms;
• a second identifier unit to identify a target confidence level;
• a synchronizer coupled to the first and second identifier units to synchronize the pool of call samples with the desired signal and the identified confidence level;
• and
• a tester coupled to the synchronizer to pass the pool of calls samples through a comparator;
• the comparator to spot the desired signal, wherein the call samples are derived from respective distinct environments, wherein spotting the desired signal comprises measuring a confidence of a presence of the desired signal in each of the call samples using correlation of the desired signal to bodies of known matching samples that are machine created reference signals, and wherein the correlation includes the comparator comprises a predictive model for performing a weighting analysis comparison of the desired signal to the bodies of known matching samples that are selected by the comparator during measuring of each of the call samples;
• a flagger to flag a given call sample as having the desired signal if the confidence for the given call sample satisfies the target confidence level;
• and
• the comparator to use the flagged sample as a reference signal of the bodies of known matching samples during a subsequent spotting of the desired signal in the pool of call samples.
