TypeError: Cannot read property 'format' of undefined

I have been trying to run the examples of this module. Unfortunately, I get always this error :

var totalDuration = info.format.duration;

You must have ffmpeg AND ffprobe both command line tools in your environment path because gspeech.api depends on node-fluent-ffmpeg
