Handling Disynchronization Phenomenawith Hmm in Connected

چکیده
Anticipation and retention phenomena between the different phonatory organs have been widely studied in the speech perception and production domain. However, few automatic speech recognition systems are able to handle them. In this paper, we deene a product of val-uated transitions automata handling these diiculties. Then, we use such automata in a recognition system based on HMM. This method is evaluated in two different contexts : bimodal and unimodal speech recognition. The results show an improvement for the the product model against a synchronous one of 1:9% in the bimodal eld and of 1:2% in the unimodal one.

Reliability Measures Improvement and Sensitivity Analysis of a Coal Handling Unit for Thermal Power Plant
The present paper investigates the reliability and sensitivity analysis of a coal handling unit of a thermal power plant using a probabilistic approach. Coal handling unit is the main block of a thermal power plant and it is necessary for a good function of a power plant that its power supply, which is dealt in coal handling unit, must function continuously without any obstacle. The configurati...
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 ...
متن کاملEnhancement of connected words in an extremely noisy environment
A speech enhancement algorithm that is based on a connected-word hidden Markov model (HMM) is developed. Speech is assumed to be highly degraded by statistically independent additive noise. The minimum mean square error estimator is derived for a connected-word HMM. Further, we derive an estimator based on a connected-word HMM with explicit state duration. Listening experiments performed with d...
متن کاملA New Fast and Efficient HMM-Based Face Recognition System Using a 7-State HMM Along With SVD Coefficients
In this paper, a new Hidden Markov Model (HMM)-based face recognition system is proposed. As a novel point despite of five-state HMM used in pervious researches, we used 7-state HMM to cover more details. Indeed we add two new face regions, eyebrows and chin, to the model. As another novel point, we used a small number of quantized Singular Values Decomposition (SVD) coefficients as feature...
