Abstract

This project aims at research and development of language-independent keyword
spotter in spoken speech. The keywords will be entered as examples
(Query-by-Example). The application of project results is in search in speech
where current approaches fail: exotic languages (insufficient or no training
data) and recordings where speakers change language within the conversation. The
first goal is to define evaluation data for several languages and to evaluate the
state-of-the-art Query-by-Example systems in cross-lingual environment. Main
goals are: (1) to design and evaluate an approach to language-independent
high-level feature extraction from speech. We will use combination of several
language-dependent artificial neural network classifiers. (2) To design and
evaluate a GMM/HMM approach to Query-by-Example. It will be important to
correctly estimate the keyword model on several examples and to investigate
training of the universal background model. We will also compare achieved results
with standard language-dependent approaches.
