Real-time factor: calculation #11

I know the metric real time factor (RTF) from STT (or ASR) systems. A RTF of 0.5 would mean than 1 sec is recognized in 0.5 sec.

I would expect a similar logic for TTS systems. But the numbers reported in larynx' debug output as Real-time factor seem to be 1/RTF. This is confusing, isn't it?

Thanks, I had forgotten to flip that. Will be updated in the next release.
