Detection of Copy-Move Forgery in Audio Signal with Mel Frequency and Delta-Mel Frequency Kepstrum Coefficients

2021 Innovations in Intelligent Systems and Applications Conference (ASYU), 2021
Digital multimedia security has taken a very important position with the developing technology. Detecting forgeries in audio signals is one of the most challenging application in the field of audio forensics. In this study, Mel Frequency and Delta Mel Frequency based methods are proposed to detect copypaste forgery in audio signals.

Compensated mel frequency cepstrum coefficients

1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002
The high concentration of energy in the low frequency range observed for most speech spectra is considered a nuisance because it makes less relevant the energy of the signal at middle and high frequencies in many speech analysis algorithms. This problem is often partially solved by filtering the input signal with a single-zero high pass filter.

Computing Mel-frequency cepstral coefficients on the power spectrum

2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002
We present a method to derive Mel-frequency cepstral coefficients directly from the power spectrum of a speech signal. We show that omitting the filterbank in signal analysis does not affect the word error rate. The presented approach simplifies the speech recognizers front end by merging subsequent signal analysis steps into a single one.

Audio Detection using Mel-frequency Cepstral Coefficients

2021 9th International Conference on Reliability, Infocom Technologies and Optimization (Trends and Future Directions) (ICRITO), 2021
The lack of benchmark findings for comparison with any suggested approach is one of the most fundamental challenges in sound event detection research. Distinct research explore different sets of events and datasets, making it difficult to distinguish between new and existing methods.

Combined audio and video watermarking using mel-frequency cepstra

IEEE International Conference on Multimedia and Expo, 2001. ICME 2001., 2001
Digital watermarking is a promising technique to help protect the data security and intellectual property right. In this paper a combined audio and video watermarking technique is proposed. Content-dependent information is extracted from the audio signal. The extraction uses a well-known feature set for audio, the melfrequency cepstra.

Cepstral analysis synthesis on the mel frequency scale

ICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
This paper presents a new technique of cepstral analysis synthesis on the mel frequency scale, the log spectrum on the mel frequency scale (the mel log spectrum) is considered to be an effective representation of the spectral envelope of speech. This analysis synthesis system uses the mel log spectrum approximation (MLSA) filter which was devised for ...

Perturbation analysis of mel-frequency cepstrum coefficients

2010 International Conference on Audio, Language and Image Processing, 2010
Mel-frequency cepstrum coefficient (MFCC) is a widely used feature vector in speech signal precessing. Its feature extraction procedure can be seen as a mapping function which transfers the input speech signals to output MFCC feature vectors. However, this function is too complex to analyze and even a simple approximation is not easy to obtain.

Chip design of mel frequency cepstral coefficients for speech recognition

2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002
The mel frequency cepstral coefficients (MFCC) is one of the mast important features, which is required among various kinds of speech applications. The chip for speech features extraction based on the MFCC algorithm is first proposed. The chip is designed with area efficient consideration and can achieve the following: (1) the reduction of table size ...
