38. A non-transitory computer-readable medium storing instructions for causing a processor of a speech processing system to: accept an original data representation of a time ordered collection of items from a first vocabulary, the original representation having been obtained by a first processing of an audio signal using the first vocabulary and comprising identification of occurrences of vocabulary items of a first vocabulary in time intervals of the audio signal in the form of a lattice or a transcript; accept a new vocabulary item not included in the original data representation obtained by the first processing of the audio signal using the first vocabulary; automatically identify, in the audio signal, a plurality of putative occurrences of the accepted new vocabulary item, including using the automatic speech processor to perform a second processing including identification of the plurality of putative occurrences in the time intervals of the audio signal in which the vocabulary items of the first vocabulary were identified in the original data representation by the first processing; and automatically process the original data representation of the time ordered collection of items from the first vocabulary and the identified plurality of putative occurrences of the new vocabulary item to form an augmented data representation of the time ordered collection of items.
