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.
