Never smoked, but often I sound like a smoker. Probably due to health conditions I've had 15+ years (inb4 "doctor", health conditions are sometimes a reality of life. We don't live in a utopia of instant or omnipotent healthcare). It's that voice stuck in throat, needing to clear your throat and like the voice doesn't pass through the nose enough (hyponasal). It makes your voice lower in pitch but quieter.
However other times once my voice is warmed up I can speak easier. I can also speak easier and more clearly when pissed off.
Similar to tips for appearing confident or relaxed by consciously knowing body language tricks (eg consciously moving slowly, consciously altering specific parts of posture, consciously giving eye contact) anyone here know tips on what to do to have a clear and loud voice even on bad days/bad hours?
