System and method of providing an automated data-collection in spoken dialog systems

A system comprising:

• a processor;
• and
• a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising:
• training a spoken dialog system using task-independent call-types of a previous application;
• recognizing a user utterance using the spoken dialog system, to yield a recognized user utterance;
• determining a rejection threshold based on an entity referenced in the recognized user utterance;
• comparing a classification of the recognized user utterance to the rejection threshold, to yield a comparison;
• and
• when the comparison indicates the recognized user utterance meets the rejection threshold, transcribing the recognized user utterance and using the recognized user utterance for further training of the spoken dialog system.
