Speech recognition is one of the areas actively commercialized using deep learning and machine learning techniques. However, the majority of speech recognition systems on the market are developed on data with limited diversity of speakers and tend to perform well on typical adult speakers only. This is because most of the speech recognition models are generally learned using a speech database obtained from adult males and females. This tends to cause problems in recognizing the speech of the elderly, children and people with dialects well. To solve these problems, it may be necessary to retain big database or to collect a data for applying a speaker adaptation. However, this paper proposes that a new end-to-end speech recognition method consists of an acoustic augmented recurrent encoder and a transformer decoder with linguistic prediction. The proposed method can bring about the reliable performance of acoustic and language models in limited data conditions. The proposed method was evaluated to recognize Korean elderly and children speech with limited amount of training data and showed the better performance compared of a conventional method.

The purpose of this study is to listen to vivid story on economic life of marriage immigrant women using phenomenological study out of qualitative study methods, and to analyze the meaning of dynamicity of experiences through in-depth interviews. The research question is "What is the meaning of economic life that marriage immigrant women experience?" From the research, 67 meaningful statements were abstracted and 15 core meanings were organized. The 15 core meanings were categorized as 5 theme categories such as 'Tough Life', 'Unstable Income such as Children Education Expense and Insurance Premium', 'Search for Changes in Life Style for Adaptation', 'Pursuit of Economic Stability through Employment', 'Expectation of Supports and Return to Married Woman's Parents' Home.' The researcher made structural description through first person speaker for the application of hermeneutical writing. In other words, the meaning of economic life of marriage immigrant women in Korea is 'difficult coping process to family-oriented culture pursuing changes in life style to adapt themselves to difficult reality.' Various undertones of practice were proposed through those statements such as policy to expand opportunities to receive an old-age pension by applying 'Joint Scheme for Couples' (Virtual Name) to People's pension for stable economic life of marriage immigrant women in old age.
