Denoising autoencoder is applied to reverberant speech recognition as a noise robust front-end to reconstruct clean speech spectrum from noisy input. In order to capture context effects of speech sounds, a window of multiple short-windowed spectra...

This paper introduces a push-pull class-E-M power amplifier for achieving low harmonic contents and high output power. By applying the push-pull configuration of the class-E-M power amplifier, the proposed amplifier achieves an extremely lower tot...

To provide an efficient means of communication for those who cannot move muscles of the whole body except eyes due to amyotrophic lateral sclerosis (ALS), we are developing a speech synthesis interface that is based on electrooculogram (BOG) input...

Direct likelihood maximization selection (DLMS) selects a subset of language model training data so that likelihood of in-domain development data is maximized. By using recognition hypothesis instead of the in-domain development data, it can be us...

For large vocabulary continuous speech recognition, speech decoders treat time sequence with context information using large probabilistic models. The software of such speech decoders tend to be large and complex since it has to handle both relati...
