Robust Formant Tracking Algorithm in Real Time Noise Environment
نویسنده
چکیده
The traditional approaches for formant frequency estimation are misled by spectral peaks in unvoiced speech and perform very poorly in transient background noise. Also, these traditional algorithms are not robust in real life noise environment and are unable to recover quickly after periods of silence. Robust formant tracking algorithm is discussed. Testing of the algorithm using various speech sentences has shown promising results over a wide range of signal to noise ratio’s (SNR’s) for various types of background included the babble (crowd of people), car, exhibition hall, restaurant, street, airport, train station and train recordings from different places. By observing the limitations of the traditional formant tracking algorithms it can be seen that the robust formant tracking algorithm is the most accurate algorithm. Results from algorithm showed that the robust formant tracking algorithm gives very good tracking performance in every environment.

Robust Formant Tracking in Echoic and Noisy Environments
We recently introduced a computationally efficient system for tracking formants. It combines a biologically inspired preprocessing for enhancing formants in spectrograms with a probabilistic framework for estimating formant trajectories. In contrast to previously published approaches our tracking scheme relies on the joint distribution of formants rather than using independent tracking instance...
متن کاملRobust Opponent Modeling in Real-Time Strategy Games using Bayesian Networks
Opponent modeling is a key challenge in Real-Time Strategy (RTS) games as the environment is adversarial in these games, and the player cannot predict the future actions of her opponent. Additionally, the environment is partially observable due to the fog of war. In this paper, we propose an opponent model which is robust to the observation noise existing due to the fog of war. In order to cope...
متن کاملA Formant Tracking Lp Model for Speech Processing in Car/train Noise
Formant estimation becomes complicated in the presence of correlated background noise such as car and train noise as the spectrum of noise from revolving mechanical sources have their own spectral peaks that affect the number and positions of the observed peaks in noisy speech spectrum. This paper investigates the modeling and estimation of spectral parameters at formants of noisy speech in the...
متن کاملDesign of robust carrier tracking systems in high dynamic and high noise conditions, with emphasis on neuro-fuzzy controller
The robust carrier tracking is defined as the ability of a receiver to determine the phase and frequency of the input carrier signal in unusual conditions such as signal loss, input signal fading, high receiver dynamic, or other destructive effects of propagation. An implementation of tight tracking can be understood in terms of adopting a very narrow loop bandwidth that contradict with the req...

This paper investigates the modeling and estimation of spectral parameters at formants of noisy speech in the presence of car and train noise. Formant estimation using twodimensional hidden Markov models (2D-HMM) is reviewed and employed to study the influence of noise on observations of formants. The first set of experimental results presented show the influence of car and train noise on the d...
