title = "Applying functional partition in the investigation of lexical tonal-pattern categories in an under-resourced Chinese dialect",
abstract = "The present study applied functional partition to investigate disyllabic lexical tonal-pattern categories in an under-resourced Chinese dialect, Jinan Mandarin. A Two-Stage partitioning procedure was introduced to process a multi-speaker corpus that contains irregular lexical variants in a semi-automatic way. In the first stage, a program provides suggestions for the phonetician to decide the lexical tonal variants for the recordings of each word, based on the result of a functional k-means partitioning algorithm and tonal information from an available pronunciation dictionary of a related Chinese dialect, i.e. Standard Chinese. The second stage iterates a functional version of k-means partitioning with Silhouette-based criteria to abstract an optimal number of tonal patterns from the whole corpus, which also allows the phoneticians to adjust the results of the automatic procedure in a controlled way and so redo partitioning for a subset of clusters. The procedure yielded eleven disyllabic tonal patterns for Jinan Mandarin, representing the tonal system used by contemporary Jinan Mandarin speakers from a wide range of age groups. The procedure used in this paper is different from previous linguistic descriptions, which were based on more elderly speakers{\textquoteright} pronunciations. This method incorporates phoneticians{\textquoteright} linguistic knowledge and preliminary linguistic resources into the procedure of partitioning. It can improve the efficiency and objectivity in the investigation of lexical tonal-pattern categories when building pronunciation dictionaries for under-resourced languages.",
