... that you can change the length of the segment that HyperTRANSCRIBE plays? Choose the Preferences menu item, and change the number of "Seconds to Play When Advancing". From now on, HyperTRANSCRIBE will play a segment of the new length when you press Shift-Space or when you press Tab to advance to the next segment.
Adjusting the segment length can help make your transcribing process more efficient. For example, if you often need to replay the segment before advancing to the next, try making the segment length shorter so that you can transcribe an entire segment in one pass. On the other hand, if you find it very easy to finish transcribing each segment without replaying it, making the segment length longer may improve your rate.
