# FrameDupl

An integer value which allows for greater time efficiency without significant change in recognition accuracy.

For example, if you set `FrameDupl` to `1`, the speed of propagation increases by approximately 50%, if set to `2`, by 67%, and if set to `3`, by 75%. HPE recommends that you do not increase `FrameDupl` beyond `4`, to maximise time efficiency as opposed to recognition accuracy.

Note: Propagation is the process of using a DNN to map audio feature frames to phonemes. Propagation time is typically 50% of the processing time.
