for each topic in the list of topics, segmenting the utterances into one or more topic segments based on a determination of an utterance boundary based on a lexical score that is a vector product associated with an adjacent pair of text blocks, wherein a vector contains a number of times a lexical item occurs within a corresponding text block;
for each of the one or more topic segments, determining whether a respective topic segment is related to a topic using one or more zero-shot text classification techniques; and
transmitting, to one or more client devices, a list of topic segments that are related to the topic.
