Improving phoneme recognition has attracted the attention of many researchers due to its applications in various fields of speech processing. Recent research achievements show that using deep neural network (DNN) in speech recognition systems significantly improves the performance of these systems. There are two phases in DNN-based phoneme recognition systems including training and testing. Mos...

The problem solved in the article is connected with increase efficiency of phraseological radio exchange message recognition, which sometimes takes place conditions increased tension for pilot. For high-quality signal preprocessing methods are needed. considers new data algorithms used to extract features from a speech message. In this case, two approaches were proposed. first approach building...

Understanding three simultaneous speeches is proposed as a challenge problem to foster artificial intelligence, speech and sound understanding or recognition, and computational auditory scene analysis research. Automatic speech recognition under noisy environments is attacked by speech enhancement techniques such as noise reduction and speaker adaptation. However, the signal-to-noise ratio of s...
