Microphone arrays have spatial selection and high signal gain, so it applies to the adverse noise conditions. In this paper, we present a new algorithm for speech enhancement based on two microphones with nonnegative matrix factorization. The interchannel characteristic of each nonnegative matrix factorization basis can be modeled by the adopted method, such as the amplitude ratios and the phase differences between channels. The results of the experiment confirm that the proposed algorithm is superior to other dual\u2010microphone speech enhancement algorithms.<\/jats:p>","DOI":"10.1155\/2018\/6153451","type":"journal-article","created":{"date-parts":[[2018,9,9]],"date-time":"2018-09-09T23:31:25Z","timestamp":1536535885000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Speech Enhancement Control Design Algorithm for Dual\u2010Microphone Systems Using <i>\u03b2<\/i>\u2010NMF in a Complex Environment"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1830-4662","authenticated-orcid":false,"given":"Dong-xia","family":"Wang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mao-song","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9395-3529","authenticated-orcid":false,"given":"Fang-lin","family":"Niu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-dong","family":"Cao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6348-9910","authenticated-orcid":false,"given":"Cheng-xu","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,9,9]]},"reference":[{"key":"e_1_2_10_1_2","first-page":"556","article-title":"Algorithms for non-negative matrix factorization","volume":"13","author":"Lee D.
