FineTracker: Introduction

This page provides information on Fine-Tracker: a computational model of human word recognition, built using techniques from the field of automatic speech recognition (ASR), which is able to capture and use fine-grained acoustic-phonetic variation during speech recognition.

Like its cousin SpeM (Scharenborg et al., 2005), Fine-Tracker can take realistic representations of the speech signal as its input and subsequently perform a word search based on the theory of human word recognition as explained in Norris (1994). Fine-Tracker takes multi-tier vector representations of the speech signal, for instance created by an artificial neural network, as its input. The output of Fine-Tracker consists of an Nbest list of the most likely word sequences.
