Initial Consonant Mutation in Scottish Gaelic is considered to be morphological, somewhat idiosyncratic, and neutralizing, that is merging either the mutated sound and some underlying sound or merging two mutated sounds. This study explores articulation in one class of mutation, called Lenition (also Aspiration), asking the question of whether these sounds are articulated in the same fashion or...

This paper presents an articulatory-to-acoustic conversion method using electromagnetic midsagittal articulography (EMA) measurements as input features. Neural networks, including feed-forward deep neural networks (DNNs) and recurrent neural networks (RNNs) with long short-term term memory (LSTM) cells, are adopted to map EMA features towards not only spectral features (i.e. mel-cepstra) but al...

Our acoustic to articulatory inversion method exploits an original codebook representing the articulatory space by hypercubes. The articulatory space is decomposed into regions where the articulatory-to-acoustic mapping is linear. Each region is represented by a hypercube. The inversion procedure retrieves articulatory vectors corresponding to an acoustic entry from the hypercube codebook. The ...

This paper presents results from Japanese intonation modelling using PENTAtrainer2, an articulatory synthesiser. Our first aim is to show that PENTA, on which PENTAtrainer2 is based, can achieve high accuracy in predictive synthesis of varying intonation contours. We trained the synthesiser on a 6251-sentence functionally annotated corpus and generated F0 contours for each communicative conditi...

This work describes ongoing data collection of synchronized acoustic and kinematic features of dysarthric speech. Recordings consist of electromagnetic articulographic measurements and 3D reconstructions from video over a variety prompts read by individuals with cerebral palsy and matching nondysarthric subjects. Preliminary results show a preponderance of mispronounced plosives in dysarthric s...

Neuro-physical investigations [1] hint to a new paradigm for feature extraction not used in ASR. This paradigm is based on synchronized brain to brain oscillations, active during speech production and speech perception. This mechanism leads to an evolving theory, the author calls the Unified Theory of Human Speech Processing (UTHSP). The core elements of this theory are the articulatory rhythm ...
