Spanish Nasal Assimilation Revisited: A Cross-Dialect Electropalatographic Study, Alexei Kochetov, Laura Colantoni

Alexei Kochetov

This study employs electropalatography to investigate the implementation of nasal assimilation in two Spanish dialects (Argentine and Cuban) that differ in the realization of word-final nasals as alveolar or velar. 5 speakers of Argentine and 3 speakers of Cuban Spanish were presented with various utterances containing nasals followed by labial, coronal, and dorsal stops and fricatives under two stress conditions. Results revealed that place assimilation of nasals was consistently accompanied by stricture assimilation. The process was generally categorical, that is, the final alveolar or velar nasal adopted the articulation of the following consonant. Nasal + fricative sequences, however, showed a …

Prosodylab-Aligner: A Tool For Forced Alignment Of Laboratory Speech, Kyle Gorman, Jonathan Howell, Michael Wagner

The Penn Forced Aligner automates the alignment process using the Hidden Markov Model Toolkit (HTK). The core of Prosodylab-Aligner is align.py, a script which performs acoustic model training and alignment. This script automates calls to HTK and SoX, an open-source command-line tool which is capable of resampling audio. The included README file provides instructions for installing HTK and SoX on Linux and Mac OS X, and can also be run on Windows. During training, the model is initialized with flat-start monophones, which are then submitted to a single round of model estimation. Then, a tied-state 'small pause' model is inserted …
