1. A system comprising:

  • a processor; and

    a computer-readable medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising;

    inserting, via a discriminative classification approach independent of an n-gram approach, boundary tags, word by word, into speech utterance text, the boundary tags identifying boundaries selected from a group consisting of phrase boundaries, sentence boundaries, and paragraph boundaries, wherein the discriminative classification approach utilizes syntactic features before and after each word being tagged, to yield boundary marked speech utterance text;

    thereafter, inserting, via the discriminative classification approach, edit tags in the boundary marked speech utterance text to identify at least one word of a set of duplicated words, to yield edited text and unedited text, wherein each edit tag comprises edit span information indicating how many words to the left of each edit tag to edit;

    thereafter, identifying coordinating conjunctions within the unedited text based on a conjunction tag, to yield identified coordinating conjunctions, wherein the conjunction tag comprises conjunction span information indicating how many words to the left of the conjunction tag a corresponding conjunction includes; and

    identifying clauses in the speech utterance text based on the boundary marked speech utterance text, the edited text, and the identified coordinating conjunctions.
