Success and failure are absolute states in this method. A solution that doesn't
|
|
match the audio content results in failure while a match is considered a
|
|
success. But when above-mentioned circumvention methods are used, there will be
|
|
results will be completely inaccurate and as the system lacks any adaptational
|
|
capabilities, the failure will be long-lasting.
|
|
|
|
The method uses only challenge solutions in its decision process. No other
|
|
external factors are involved.
