In the last decade, enormous data are being shared throughout the world. In many of today’s big data world, the companies are trying to use some sentiment or emotion analysis techniques to analyze their customer moods and improve their efficiencies according to sentiments. As a different application we focused on the sentiment analysis of closed places in this research. It requires low noise environments obviously. Otherwise, system may be affected by distortion, and it may be contradiction for multiple sentiments. In this regard, an artificial neural network using meaningful voice features are proposed. Ryerson Audio Visual Database of Emotional Speech and Song (RAVDESS) dataset was used in this research. Normalization was applied to data. The artificial neural network was fed by training data and a classifier model was created. Estimation was made using the test data part and it was seen that accuracy of model is about 85%.
