A mistake most people make in voice projection is holding their breath when speaking. This is resulted out of stress, nervousness, fear, etc. Do you still remember the last time when you were asked at the last minute to speak for 2 minutes, or informed by your boss to submit your report immediately? The stress and nervousness gave you chill that ran down your spine, reflecting in your voice as tight, perhaps mumble a bit, or squeaky? Those are all the results of holding your breath while speaking due to nervousness or high-level stress.
To ease that, simply breathing out when you speak. Remember, “Speaking always happens on the breathing out.”
