【 摘 要 】

We present a computational evaluation of a hypothesis according to which distributional information is sufficient to acquire allophonic rules (and hence phonemes) in a bottom-up fashion. The hypothesis was tested using a measure based on information theory that compares distributions. The test was conducted on several artificial language corpora and on two natural corpora containing transcriptions of speech directed to infants from two typologically distant languages (French and Japanese). The measure was comple-mented with three filters, one concerning the statistical reliability due to sample size and two concerning the following universal properties of allophonic rules: constituents of an allophonic rule should be phonetically similar, and allophonic rules should be assimilatory in nature
