Studies with Fabricated Switchboard Data: Exploring Sources of Model-data Mismatch
We present a study of data simulated using acoustic models trained on Switchboard data, and then recognized using various Switchboard-trained acoustic models. The Switchboard-trained models yield word error rates of about 47 percent, on real Switchboard conversations. When data is simulated using the acoustic models, but in a way that insures that the pronunciations in our recognition dictionar...
متن کاملRestricted cascade and wreath products of fuzzy finite switchboard state machines
A finite switchboard state machine is a specialized finite state machine. It is built by binding the concepts of switching state machines and commutative state machines. The main purpose of this paper is to give a specific algorithm for fuzzy finite switchboard state machine and also, investigates the concepts of switching relation, covering, restricted cascade products and wreath products of f...
متن کاملRapid speech recognizer adaptation to new speakers
This paper summarizes the work of the “Rapid Speech Recognizer Adaptation” team in the workshop held at Johns Hopkins University in the summer of 1998. The project addressed the modeling of dependencies between units of speech with the goal of making more effective use of small amounts of data for speaker adaptation. A variety of methods were investigated and their effectiveness in a rapid adap...
متن کاملResegmentation of SWITCHBOARD
The SWITCHBOARD (SWB) corpus is one of the most important benchmarks for recognition tasks involving large vocabulary conversational speech (LVCSR). The high error rates on SWB are largely attributable to an acoustic model mismatch, the high frequency of poorly articulated monosyllabic words, and large variations in pronunciations. It is imperative to improve the quality of segmentations and tr...
متن کاملPronunciation modelling using a hand-labelled corpus for conversational speech recognition
Accurately modelling pronunciation variability in conversational speech is an important component of an automatic speech recognition system. We describe some of the projects undertaken in this direction during and after WS97, the Fifth LVCSR Summer Workshop, held at Johns Hopkins University, Baltimore, in JulyAugust, 1997. We first illustrate a use of hand-labelled phonetic transcriptions of a ...
