Evaluation of objective measures for intelligibility prediction of HMM-based synthetic speech in noise
In this paper we evaluate four objective measures of speech with regards to intelligibility prediction of synthesized speech in diverse noisy situations. We evaluated three intell...

Seismic waves estimation and wave field decomposition with factor graphs
Physical wave fields are often described by means of a vector field. Advances in sensor technology enable us to collect an increasing number of measurement at the same location ...

Very low bit-rate F0 coding for phonetic vocoder using MSD-HMM with quantized F0 context
This paper presents a very low bit-rate F0 coding technique for speaker-dependent phonetic vocoder based on hidden Markov model (HMM) using quantized F0 context. In the proposed t...

Investigation of acoustic units for LVCSR systems
One important issue in designing state-of-the-art LVCSR systems is the choice of acoustic units. Context dependent (CD) phones remain the dominant form of acoustic units. They can...
