Comparative Study between the Discrete-Frequency Kalman Filtering and the Discrete-Time Kalman Filtering with Application in Noise Reduction in Speech Signals by Leandro Aureliano da Silva, Gilberto Arantes Carrijo, Eduardo Silva Vasconcelos, Roberto Duarte Campos, Cleiton Silvano Goulart, Rodrigo Pinto Lemos

“…In order to assess the performance of both methods for speech reconstruction, we measured the output segmental signal-to-noise ratio and the Itakura-Saito distance provided by each algorithm over 25 different voice signals. The results show that although the two algorithms performed very similarly regarding noise reduction, the discrete-time Kalman filter produced smaller spectral distortion on the estimated signals when compared with the discrete-frequency Kalman filter.…”
