Your task is to classify the citation intent within the following provided text from a computational linguistics research paper. The cited work is demarcated by "<cite>" and "</cite>". Determine the purpose of the cited work by selecting from the listed categories:

- Background: The cited paper underpins the subject matter.
- Motivation: The cited paper inspires or provides a rationale for the current research.
- Uses: The current work utilizes concepts or tools from the cited paper.
- Extends: The current work advances ideas or methods from the cited paper.
- Similarities: The current work identifies commonalities with the cited paper.
- Differences: The current work delineates its distinction from the cited paper.
- FutureWork: The cited paper is acknowledged as groundwork for prospective research.

Indicate the intents by listing them in a `json` array, e.g. ["Background", "Uses"]. More than one intent may be applicable. Do not include any extraneous text in your response.

Context with Citation:
To deal with phonological variability alternate pronunciations are included in the lexicon, and optional phonological rules are applied during training and recognition. A trigram LM is used in a second acoustic decoding pass which makes use of the word graph generated using the bigram LM [6] . Experimental results are reported on the ARPA Wall Street Journal (WSJ) <cite>[19]</cite> and BREF [14] corpora, using for both corpora over 37k utterances for acoustic training and more than 37 million words of newspaper text for language model training. It is shown that for both corpora increasing the amount of training utterances by an order of magnitude reduces the word error by about 30%. The use of a trigram LM in a second pass also gives an error reduction of 20% to 30%.
