Yup.

Directional microphones that can help reject unwanted sounds - be they
other voices or indeed 'acoustic' - are large and *very* expensive. Like
the best part of a grand for the industry standard. And even with one of
those, to get decent quality speech it needs to be quite close. With the
average omni that most of these type of machines use, you're on a hiding
to nothing.

A good example is the sort of personal mics you'll see on newsreaders,
etc. Not bad quality when close, as they are when worn, but have you heard
what they sound like when they've fallen off etc and are only a few feet
away? Near unintelligible. In a reasonably quiet studio.
