Handset-Dependent Background Models for Robust Text-Independent Speaker Recognition
This paper studies the effects of handset distortion on telephone-based speaker recognition performance. Results on the 1996 NIST Speaker Recognition Evaluation corpus show that using handset-matched background models reduces false…

Automatic Pronunciation Scoring for Language Instruction
In this paper we show that we can significantly improve HMM- based scores by using average phone segment posterior probabilities. Correlation between machine and human scores went up from r=0.50…

Acoustic Modeling for the SRI Hub4 Partitioned Evaluation Continuous Speech Recognition System
We describe the development of the SRI system evaluated in the 1996 DARPA continuous speech recognition (CSR) Hub4 partitioned evaluation (PE). The task for the Hub4 evaluation was to recognition…

Hub4 Language Modeling Using Domain Interpolation and Data Clustering
In SRI's language modeling experiments for the Hub4 domain, three basic approaches were pursued: interpolating multiple models estimated from Hub4 and non-Hub4 training data, adapting the language model (LM) to…

On the determination of epipoles using cross-ratios
We study the problem of computing the position of the epipoles in a pair of uncalibrated images. The approach, which is based on the invariance of the cross-ratio by the…
