Brent (1999a) points out one type of ambiguity, namely that Saffran and colleagues' (1996) results can be modeled as favoring word-breaks at points of either low transitional probability or low mutual information. Brent reports results for models relying on each of these measures. It should be noted that these models are not the main focus of his paper, but provided for illustrative purposes; nevertheless, these models provide the best comparison to Saffran and colleagues' experiment, and may be regarded as an implementation of the same.
