Verify temporal metric #254

Closed vvasco closed 4 years ago

vvasco commented 4 years ago

We want to be sure that the computed time is not affected by disturbances (such as questions during the test).

I used a stopwatch to compare the time we compute to a ground truth. I realized that speaking was introducing latency in the computation of the starting time: to trigger the start, the robot pronounces a sentence and we were waiting for the sentence to be pronounced and computing the starting time only after. As a result, the time computed was lower than the ground truth. I improved this in ee33af1, by splitting the sentence in two shorter ones, and avoid waiting when triggering the start. With this change, the temporal metric is reasonable.
