Speech recognition using facial sEMG

2017 IEEE International Conference on Signal and Image Processing Applications (ICSIPA), 2017
This paper presents a study of speech recognition based on electromyographic biosignals captured from the articulatory muscles in the face using surface electrodes. This paper compares the speech recognition system for spoken English and Malay words by a group of Malay native speakers.

sEMG-based lip shapes recognition

2019 IEEE International Conference on Computational Intelligence and Virtual Environments for Measurement Systems and Applications (CIVEMSA), 2019
With the development of intelligent technology, the need for more effective and practical human-computer interaction becomes more and more urgent. The objective of this paper is to use the facial surface electromyography (sEMG) for lip shapes recognition.

Towards High Density sEMG (HD-sEMG) Acquisition Approach for Biometrics Applications

2019
This is the third chapter of this book dedicated to EMG biometrics modality. The purpose is to highlight a Multi-Channel technique based on a High Density sEMG (HD-sEMG) acquisition. In fact, HD-sEMG recording systems can be used to overcome the limitation of classical bipolar and monopolar sEMG recording systems.

Pattern Mining of Multichannel sEMG for Tremor Classification

IEEE Transactions on Biomedical Engineering, 2010
Tremor is defined as the involuntary rhythmic or quasi-rhythmic oscillation of a body part, resulting from alternating or simultaneous contractions of antagonistic muscle groups. While tremor may be physiological, those who have disabling pathological tremors find that performing typical activities for daily living to be physically challenging and ...

Analyzing an sEMG signal using wavelets

2009
Electromyography (EMG) is an experimental technique developed with the purpose of detecting muscle movement. The technique generates a signal that is formed by impulses of muscle fibers during the movement of muscles. The generated signal is very sensitive and can therefore be influenced by several external factors altering its shape and ...

Electrode distance and magnitude of SEMG

Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002
This paper reports experimental research undertaken to study the effect of variation of inter-electrode distance on the Surface Electromyogram (SEMG). The experiments were conducted on ten healthy subjects and they performed isometric contraction of their biceps of the right arm at 20, 50 and 80% of their maximal voluntary contraction (MVC).

An improved method for sEMG segmentation

2012 24th Chinese Control and Decision Conference (CCDC), 2012
An improved method of continuous action's sEMG automatic segmentation is presented in this paper. The maximum value and the integral value of local area are regarded as the distinguishing standard for start or stop action area, and search area adjusted dynamicly can speed up the sEMG segmentation. The experiment results show that, the methods which are

Study on Online Gesture sEMG Recognition

2007
We have realized an online gesture recognition platform for hand gestures using 2-channel surface EMG signals acquired from the forearm. Several features, such as AMV, AMV ratio and fourth-order AR model coefficients are extracted from the sEMG signal and the gesture segments are recognized with a Weighted Euclidean Distance Classifier.

SEMG-controlled telephone interface for people with disabilities

Journal of Medical Engineering & Technology, 2002
This paper proposes the development of a surface electromyographic (SEMG)-controlled telephone interface for the disabled. The system is composed of three major components: (1) a SEMG receiving/signal-processing module; (2) a row-column scanning interface for the telephone dialling pad; and (3) a main controller, the Intel-8951 microprocessor.

A new and fast approach towards sEMG decomposition

Medical & Biological Engineering & Computing, 2013
The decomposition of high-density surface EMG (HD-sEMG) interference patterns into the contribution of motor units is still a challenging task. We introduce a new, fast solution to this problem. The method uses a data-driven approach for selecting a set of electrodes to enable discrimination of present motor unit action potentials (MUAPs).
