In this paper, we explore the use of large-scale acoustic unit discovery for language recognition. The deep neural network-based approaches that have achieved recent success in this task require transcribed speech and pronunciation dictionaries, which may be limited in availability and expensive to obtain. We aim to replace the need for such supervision via the unsupervised discovery of acoustic units...
Zero-resource speech processing involves the automatic analysis of a collection of speech data in a completely unsupervised fashion without the benefit of any transcriptions or annotations of the data. In this paper, our zero-resource system seeks to automatically discover important words, phrases and topical themes present in an audio corpus. This system employs a segmental dynamic time warping (S-DTW)...
