In this abstract, the performance of a triggered cine-MRI sequence is evaluated in the context of dynamic imaging of the vocal tract for linguistics and phonetics studies. The synchronization precision of this method is evaluated using wide band spectrograms of the recorded speech output. It is demonstrated that the use of this approach allows for the acquisition of dynamic images with high spatial resolution and high signal-to-noise ratio, along with a relatively good temporal fidelity (~ 30 ms).
