The speedoMeter is a digital tool that can indicate if the speaker at a conference is speaking too fast for the interpreter to deliver a top-notch translation of the talk.
The speedoMeter listens to the speaker and indicates by means of numbers (estimated words per minute) and a color (green-yellow-red) if the speaker is too fast. It could be used to automate the signaling to slow down the pace.
