Title:       Automatically Learning the Structure of Spoken Language
Without Supervision

Abstract:

The dominant paradigm in the speech recognition community for the past four
decades has been to train automatic systems with as much transcribed data
we can get our greedy hands on. This strategy has led to the development of
highly accurate systems that have finally found a place in our daily lives
in the form of popular applications such as Apple iPhone's Siri.  An
unfortunate consequence of this trajectory, however, is that
state-of-the-art recognition performance can only be achieved on languages
and domains for which vast transcribed training resources either exist or
can be easily obtained. Meanwhile, with public internet resources like
YouTube and PodCasts, untranscribed speech audio is abundant and contains a
wealth of hidden information regarding the acoustic-phonetic, lexical,
grammatical, and semantic structure of the language being spoken. The trick
is uncovering this structure automatically, an endeavor that will require
new machine learning techniques, algorithms scalable to massive problem
sizes, and a lot of patience.  I will provide an overview of my efforts in
these directions and describe some useful language- and domain-independent
technologies that have been produced along the way.
