Multichannel Robot Speech Recognition Database: MChRSR
José Novoa, Juan Pablo Escudero, Josué Fredes +3
In real human robot interaction (HRI) scenarios, speech recognition represents a major challenge due to robot noise, background noise and time-varying acoustic channel. This docume…
Estimation of Exoplanetary Planet-to-Star Radius Ratio with Homomorphic Processing
Rodrigo Mahu, Patricio Rojo, Ali Dehghan Firoozabadi +3
In this paper a homomorphic filtering scheme is proposed to improve the estimation of the planet/star radius ratio in astronomical transit signals. The idea is to reduce the effect…
Unsupervised Method for Correlated Noise Removal for Multi-wavelength Exoplanet Transit Observations
Ali Dehghan Firoozabadi, Alejandro Diaz, Patricio Rojo +4
Exoplanetary atmospheric observations require an exquisite precision in the measurement of the relative flux among wavelengths. In this paper, we aim to provide a new adaptive meth…
DNN-based uncertainty estimation for weighted DNN-HMM ASR
José Novoa, Josué Fredes, Néstor Becerra Yoma
In this paper, the uncertainty is defined as the mean square error between a given enhanced noisy observation vector and the corresponding clean one. Then, a DNN is trained by usin…
