1. A computer-implemented method comprising:
receiving a training set of utterances for training an intent classifier to identify one or more intents for one or more utterances;
augmenting the training set of utterances with noise text to generate an augmented training set of utterances, wherein the augmenting is performed using one or more noise augmentation operations that comprise:
obtaining the noise text as random strings of text generated from a list of stop words or a dictionary, or as sentences copied verbatim or shuffled from a corpus of text, wherein the noise text is obtained irrelevant of original text within the utterances of the training set of utterances; and
incorporating the noise text within the utterances relative to the original text in the utterances of the training set of utterances to generate augmented utterances, wherein the incorporating comprises:
(i) incorporating the random strings of text generated from the list of stop words or the dictionary in front of the original text within the utterances, after the original text of the utterances, flanking the original text of the utterances, integrated within the original text of the utterances, or any combination thereof; or
(ii) incorporating the sentences copied verbatim or the sentences copied shuffled in front of the original text within the utterances, after the original text of the utterances, flanking the original text of the utterances, integrated within the original text of the utterances, or any combination thereof; and
