Leveraging Speaker-dependent Va

چکیده
This work introduces an automatic procedure for determining the size of regression class trees for individual speakers using an ensemble of speaker-level features to control the number of transformations, if any, that should be estimated by maximum likelihood linear regression. Experiments with a state-of-the-art speech recognition system that uses this procedure show improvements in word error rate for conversational telephone speech.

On leveraging conversational data for building a text dependent speaker verification system
Recently we have investigated the use of state-of-the-art textindependent and text-dependent speaker verification algorithms for a text-dependent user authentication task and obtained satisfactory results mainly by using a fair amount of text-dependent development data. In our study, best results were obtained using the NAP framework rather than using the more advanced JFA and i-vector-based fr...
متن کاملIn-set/out-of-set speaker recognition in sustained acoustic scenarios using sparse data
This study addresses the problem of identifying in-set versus out-of-set speakers in noise for limited train/test durations in situations where rapid detection and tracking is required. The objective is to form a decision as to whether the current input speaker is accepted as a member of an enrolled in-set group or rejected as an outside speaker. A new scoring algorithm that combines log likeli...

متن کاملEnhancing health and independent living for veterans with disabilities by leveraging community-based resources
The number of US veterans with disabilities has increased in recent years as service members have returned home with extensive injuries and veterans from previous wars acquire functional limitations as a consequence of aging with chronic diseases. Veterans with severe disabilities need assistance and support to maintain independence at home and to avoid institutionalization. The US Department o...
