  Simultaneous text translation and end-to-end speech translation have recently
made great progress but little work has combined these tasks together. We
investigate how to adapt simultaneous text translation methods such as wait-k
and monotonic multihead attention to end-to-end simultaneous speech translation
by introducing a pre-decision module. A detailed analysis is provided on the
latency-quality trade-offs of combining fixed and flexible pre-decision with
fixed and flexible policies. We also design a novel computation-aware latency
metric, adapted from Average Lagging.
