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.<\/jats:p>","DOI":"10.1155\/2018\/1895190","type":"journal-article","created":{"date-parts":[[2018,6,3]],"date-time":"2018-06-03T19:31:26Z","timestamp":1528054286000},"page":"1-5","source":"Crossref","is-referenced-by-count":0,"title":["Comparative Study between the Discrete-Frequency Kalman Filtering and the Discrete-Time Kalman Filtering with Application in Noise Reduction in Speech Signals"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2050-2249","authenticated-orcid":true,"given":"Leandro Aureliano","family":"da Silva","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Universidade Federal de Uberl\u00e2ndia, Av.
