HMM-based speech synthesis using sub-band basis spectrum model
نویسندگان
چکیده
In this paper, we propose HMM-based text-to-speech (TTS) using sub-band basis spectrum model (SBM). SBM can represent vocal tract spectra and phase characteristics by a linear combination of sub-band basis vectors. Some reports suggest that analysis-synthesized speech based on SBM is close to natural speech and SBM can perform effectively in TTS. Therefore, the SBM framework is expected to have good effects on HMMbased TTS by improving speech quality. Subjective experimental results show that the proposed method improves speech quality in some conditions.

Sub-band text-to-speech combining sample-based spectrum with statistically generated spectrum
As described in this paper, we propose a sub-band speech synthesis approach to develop a high quality Text-to-Speech (TTS) system: a sample-based spectrum is used in the high-frequency band and spectrum generated by HMM-based TTS is used in the low-frequency band. Herein, sample-based spectrum means spectrum selected from a phoneme database such that it is the most similar to spectrum generated...
متن کاملSub-band basis spectrum model for pitch-synchronous log-spectrum and phase based on approximation of sparse coding
In this paper, we propose a sub-band basis spectrum model which is a new spectrum representation model based on a linear combination of sub-band basis vectors. We apply sparse coding to the pitch-synchronously analyzed log-spectra. Based on the approximation of the resulting basis, we obtain subband basis vectors with 1-cycle sinusoidal shapes that have mel-scale for lower frequencies and equal...
متن کاملSpeech enhancement based on hidden Markov model using sparse code shrinkage
This paper presents a new hidden Markov model-based (HMM-based) speech enhancement framework based on the independent component analysis (ICA). We propose analytical procedures for training clean speech and noise models by the Baum re-estimation algorithm and present a Maximum a posterior (MAP) estimator based on Laplace-Gaussian (for clean speech and noise respectively) combination in the HMM ...

In recent years, sub−band speech recognition has been found useful in robust speech recognition, especially for speech signals contaminated by band−limited noise. In sub−band speech recognition, full band speech is divided into several frequency sub−bands and then sub−band feature vectors or their generated likelihoods by corresponding sub−band recognizers are combined to give the result of rec...
متن کاملSimultaneous modeling of spectrum, pitch and duration in HMM-based speech synthesis
In this paper, we describe an HMM-based speech synthesis system in which spectrum, pitch and state duration are modeled simultaneously in a unified framework of HMM. In the system, pitch and state duration are modeled by multi-space probability distribution HMMs and multi-dimensional Gaussian distributions, respectively. The distributions for spectral parameter, pitch parameter and the state du...
