DNN based Acoustic Scene Classification using Score Fusion of MFCC and Inverse MFCC

2018 IEEE 13th International Conference on Industrial and Information Systems (ICIIS), 2018
Herein, we propose an Acoustic Scene Classification (ASC) based on Deep Neural Networks (DNN). The design of Mel-filer bank helps in capturing the acoustic scene characteristics in the low-frequency regions during MFCC extraction. In this paper, inverse MFCC are used as interdependent to structure of Mel filter bank.

An MFCC-Based Speaker Identification System

2017 IEEE 31st International Conference on Advanced Information Networking and Applications (AINA), 2017
Nowadays, many speech recognition applications have been used by people in the world. Typical examples are the SIRI of iPhone, Google speech recognition system, and mobile phones operated by voice, etc. On the contrary, speaker identification in its current stage is relatively immature.

Optimized MFCC feature extraction on GPU

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
In this paper, we update our previous research for Mel-Frequency Cepstral Coefficient (MFCC) feature extraction [1] and describe the optimizations required for improving throughput on the Graphics Processing Units (GPU). We not only demonstrate that the feature extraction process is suitable for GPUs and a substantial reduction in computation time can ...

Phonocardiogram classification based on MFCC extraction

2017 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA), 2017
In this work, a simple method for separation between normal and abnormal heart sounds (Phonocardiogram) is presented. Mel-Frequency Cepstral Coefficients (MFCC) are extracted from two different datasets of heartbeats. Several Classifiers, such as, Support Vectors Machine (SVM), K-Nearest Neighbors (KNN), Naive Bayes (NB), Classification Tree (CT) and ...

Keyword Recognition Based on MFCC

Advanced Materials Research, 2014
After about 50 years of development, speech recognition technology has been able to achieve large vocabulary, non-specific human continuous speech recognition system. On account of Chinese pronunciation features, we research the small vocabulary, non-specific Chinese speech recognition based on continuous Hidden Markov Model approach.

The impact of the pitch on the estimation of MFCC

2011 19thTelecommunications Forum (TELFOR) Proceedings of Papers, 2011
In this paper, the impact of the pitch on the variability of MFCC, and their influence on the performance of the automatic speech recognition system, is analyzed. In case that a speaker has a high pitch, the distance between adjacent harmonics in the spectrum of voiced phonemes is larger, which results in poorer description of the spectral envelope ...

Chip design of MFCC extraction for speech recognition

The Integration VLSI Journal, 2002
Summary: The Mel Frequency Cepstral Coefficient (MFCC) is one of the most important features required among various kinds of speech applications. In this paper, the first chip for speech features extraction based on MFCC algorithm is proposed. The chip is implemented as an intellectual property, which is suitable to be adopted in a speech recognition ...

Speech Emotion Recognition Based on Improved MFCC

Proceedings of the 2nd International Conference on Computer Science and Application Engineering, 2018
Speech1 Emotion Recognition SER uses the Berlin EMO-DB database, seven emotions. Traditional emotional features and their statistics are used in SER. Two improved Mel Frequency Cepstrum Coefficients MFCC features are added to this experiment, which extract MFCC parameters from the energy curve and the fundamental frequency curve, that are energy MFCC ...
