Given its complexity, an automatic cry segmentation system is a rather challenging topic. In this paper, a framework for automatic cry sound segmentation for application in a cry-based diagnostic system has been proposed. The contribution of various additional time- and frequency-domain features to increase the robustness of a Gaussian mixture model\/hidden Markov model (GMM\/HMM)-based cry segmentation system in noisy environments is studied. A fully automated segmentation algorithm to extract cry sound components, namely, audible expiration and inspiration, is introduced and is grounded on two approaches: statistical analysis based on GMMs or HMMs classifiers and a post-processing method based on intensity, zero crossing rate, and fundamental frequency feature extraction. The main focus of this paper is to extend the systems developed in previous works to include a post-processing stage with a set of corrective and enhancing tools to improve the classification performance. This full approach allows to precisely determine the start and end points of the expiratory and inspiratory components of a cry signal, EXP and INSV, respectively, in any given sound signal. Experimental results have indicated the effectiveness of the proposed solution. EXP and INSV detection rates of approximately 94.29% and 92.16%, respectively, were achieved by applying a tenfold cross-validation technique to avoid over-fitting.<\/jats:p>","DOI":"10.1121\/1.5001491","type":"journal-article","created":{"date-parts":[[2017,9,11]],"date-time":"2017-09-11T15:39:10Z","timestamp":1505144350000},"page":"1318-1331","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":32,"title":["A fully automated approach for baby cry signal segmentation and boundary detection of expiratory and inspiratory episodes"],"prefix":"10.1121","volume":"142","author":[{"given":"Lina","family":"Abou-Abbas","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, \u00c9cole de Technologie Sup\u00e9rieure, Quebec University , 1100 Rue Notre Dame Ouest, Montr\u00e9al, Quebec H3C 1K3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chakib","family":"Tadj","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, \u00c9cole de Technologie Sup\u00e9rieure, Quebec University , 1100 Rue Notre Dame Ouest, Montr\u00e9al, Quebec H3C 1K3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hesam Alaie","family":"Fersaie","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, \u00c9cole de Technologie Sup\u00e9rieure, Quebec University , 1100 Rue Notre Dame Ouest, Montr\u00e9al, Quebec H3C 1K3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2017,9,11]]},"reference":[{"key":"2023071620114130900_c2","first-page":"796","article-title":"Segmentation of voiced newborns' cry sounds using wavelet packet based features","year":"2015"},{"key":"2023071620114130900_c3","doi-asserted-by":"publisher","first-page":"35","DOI":"10.1016\/j.bspc.2015.03.007","article-title":"Automatic detection of the expiratory and inspiratory phases in newborn cry signals","volume":"19","year":"2015","journal-title":"Biomed.
