Deep CNNs have achieved a great success in acoustic modelling for automatic speech recognition due to its ability of reducing spectral variations and modelling spectral correlations in the input features. In most of the acoustic modelling using CNN, a fixed windowed feature patch corresponding to a target label (e.g., senone or phone) was used as input to the CNN. Considering different target labels may correspond to different time scales, multiple acoustic models were trained with different acoustic feature scales. Due to auxiliary information learned from different temporal scales could help in classification, multi-CNN acoustic models were combined based on a Recognizer Output Voting Error Reduction (ROVER) algorithm for final speech recognition experiments. The experiments were conducted on a Myanmar large vocabulary continuous speech recognition (LVCSR) task. Our results showed that integration of temporal multi-scale features in model training achieved a 4.32% relative word error rate (WER) reduction over the best individual system on one temporal scale feature.</p>"}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"acoustic modelling"},{"interim":"deep convolutional neural networks"},{"interim":"multi-scale features"},{"interim":"Myanmar speech recognition"},{"interim":"ROVER combination"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2019-06-27"}],"displaytype":"preview","filename":"Combination of Multiple Acoustic Models with Multi-scale Features for Myanmar Speech Recognition.pdf","filesize":[{"value":"334 Kb"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/3097/files/Combination of Multiple Acoustic Models with Multi-scale Features for Myanmar Speech Recognition.pdf"},"version_id":"d8e68a24-e5a8-4825-a570-7c63f43d9cee"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"No. 1","subitem_journal_title":"International Journal of Computer","subitem_pages":"pg 112-121","subitem_volume":"Vol. 28"}]},"item_1583103147082":{"attribute_name":"Conference papers","attribute_value_mlt":[{"subitem_acronym":"","subitem_c_date":"","subitem_conference_title":"","subitem_part":"","subitem_place":"","subitem_session":"","subitem_website":""}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{"subitem_book_title":"","subitem_isbn":"","subitem_pages":"","subitem_place":"","subitem_publisher":""}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_awarding_university":"","subitem_supervisor(s)":[{"subitem_supervisor":""}]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Thandar Soe"},{"subitem_authors_fullname":"Su Su Maung"},{"subitem_authors_fullname":"Nyein Nyein Oo"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2018-10-25"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"10.5281/zenodo.3068568"},"item_title":"Combination of Multiple Acoustic Models with Multi-scale Features for Myanmar Speech Recognition","item_type_id":"21","owner":"1","path":["1596119372420"],"publish_date":"2019-06-27","publish_status":"0","recid":"3097","relation_version_is_last":true,"title":["Combination of Multiple Acoustic Models with Multi-scale Features for Myanmar Speech Recognition"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-03-24T23:15:13.316008+00:00"}
