Efficient data selection for ASR
Automatic speech recognition (ASR) technology has matured over the past few decades and has made significant impacts in a variety of fields, from assistive technologies to commercial products. However, ASR system development is a resource intensive activity and requires language resources in the form of text annotated audio recordings and pronunciation dictionaries. Unfortunately, many language...
متن کاملAutomatic data selection for MLP-based feature extraction for ASR
The use of huge databases in ASR has become an important source of ASR system improvements in the last years. However, their use demands an increase of the computational resources necessary to train the recognizers. Several techniques have been proposed in the literature with the purpose of making a better use of these enormous databases by selecting the most ‘informative‘ portions and thus red...
متن کاملKullback-Leibler Divergence-Based ASR Training Data Selection
Data preparation and selection affects systems in a wide range of complexities. A system built for a resource-rich language may be so large as to include borrowed languages. A system built for a resource-scarce language may be affected by how carefully the training data is selected and produced. Accuracy is affected by the presence of enough samples of qualitatively relevant information. We pro...
متن کاملData-intensive approaches for ASR
Although many important scientific advances have taken place in automatic speech recognition research, we have also encountered a number of practical limitations which hinder a widespread deployment of applications and services. In most speech recognition tasks, human subjects produce one to two orders of magnitude fewer errors than machines. One of the most significant differences exists in th...
متن کاملEfficient Parameters Selection for CNTFET Modelling Using Artificial Neural Networks
In this article different types of artificial neural networks (ANN) were used for CNTFET (carbon nanotube transistors) simulation. CNTFET is one of the most likely alternatives to silicon transistors due to its excellent electronic properties. In determining the accurate output drain current of CNTFET, time lapsed and accuracy of different simulation methods were compared. The training data for...
