Time synchronization of speech

چکیده
A time synchronization system is a helpful tool for different applications, such as language education and speech therapy. We present a system that performs temporal alignment of two utterances of the same phrase. The system consists of two parts. In the first part the time warping function is determined with Dynamic Time Warping (DTW). In the second part the time scale of one utterance is modified according to the time warping function. To obtain good performance, the dynamic time warping algorithm required significant modifications. Our listening test confirms that our time synchronization system has high precision and the resulting speech utterances are of natural quality.

Synchronization for Complex Dynamic Networks with State and Coupling Time-Delays
This paper is concerned with the problem of synchronization for complex dynamic networks with state and coupling time-delays. Therefore, larger class and more complicated complex dynamic networks can be considered for the synchronization problem. Based on the Lyapunov-Krasovskii functional, a delay-independent criterion is obtained and formulated in the form of linear matrix inequalities (LMIs)...

In this paper, under the existence of system uncertainties, external disturbances, and input nonlinearity, global finite time synchronization between two identical attractors which belong to a class of second-order chaotic nonlinear gyros are achieved by considering a method of continuous smooth second-order sliding mode control (HOAMSC). It is proved that the proposed controller is robust to m...

In this paper, linear matrix inequality (LMI) approach for synchronization of chaotic fuzzy cellular neural networks (FCNNs) with discrete and unbounded distributed delays based on sampled-data controlis investigated. Lyapunov-Krasovskii functional combining with the input delay approach as well as the free-weighting matrix approach are employed to derive several sufficient criteria in terms of...
متن کاملA Survey – Audio and Video Synchronization
The audio and video Synchronization is extremely necessary. The synchronization loss between image and sound continues to disturb observers and irritate telecasters. The demand is to assure synchronization without adjusting content at the same time as still retaining price low. The objective of the synchronization is to line up both the audio and video signals that are processed individually. T...
