Audio problems are often down to differences in audio sampling frequency. If the voice-over track happens to be 48kHz but the music is 44.1kHz (which is what YouTube prefers) if you chose the YouTube Export option I wonder whether MEP is trying to resample the VO track and hence "skipping" some "words"?
I know most video needs audio at 48kHz but I know that YT specifically "recommends" 44.1 for its service.
When I record the audio on Magix, it is garbled ... craftmanship sounds like craftsmanshi*. Youtube does not seem to be the problem, this time. I recorded audio on an alternate program and imported it to Magix and it was fine; so I am thinking it is something to do with either Magix audio or the settings I am using. I am quite new at this; thanks for the input!
Like I said.....it looks like sections of the audio track are missing ie chopped out therefore truncating some words. Is there any sign of this in the project, or the voiceover track audio waveform (the wriggly line in the timeline - right click audio track > show waveform).
Are your soundcard audio drivers up to date?
A long shot is maybe - "Program Settings > Playback tab > change between Direct sound and Wave driver" settings.
As Emmrecs suggests it seems like it could be occuring in the resampling of the Audio frequency to suit the export format so may be try converting your audio before bringing it in to the timeline.
