I recently did a consultation with someone who worked as a corporate trainer, so she spoke frequently, for extended periods of time. She reported that her voice was usually gone by the end of the day, sore, raspy and almost inaudible. What’s happening here?

Assuming there’s nothing physically wrong, it’s likely she’s just overworking her voice, and that can happen in two ways. The most obvious possibility is that she’s consciously trying to “speak up” and “project” her voice, so she ends up pushing and straining. The muscles of the voice are not big, strong muscles, so they don’t perform well under pressure, and they fatigue quickly under those conditions.

Another possibility can be unconscious tension. Muscle tension creates resistance on your voice, much like friction creates resistance for moving parts in a machine. You have to work harder to overcome that resistance and that wears on your voice.

One very common source of tension is the tongue. Many speakers unconsciously pull their tongue back and down every time they make a sound. The tongue is a fairly large muscle, especially in comparison to your vocal cords, which are about the size of your thumbnail. When the tongue pulls back and down, it’s like an elephant sitting on a mouse. It becomes very hard for your vocal cords to vibrate under those conditions, so you have to use more force to overcome that resistance. Once again, your vocal cords fatigue quickly and become irritated.

So what’s the right way to cultivate vocal endurance? The strength of the voice does not lie in muscular effort, but in breath and resonance. You’re a wind instrument. Your voice is powered by breath. To find more voice, you must move more breath. (The tricky part is doing that without tension.) At some level, everyone knows this, but few people have actually experienced real breath support, as it relates to speaking.

While breath is the power of your voice, resonance is the amplification. Resonance takes the small buzz produced by your vocal cords and expands it into the unique sound that is your voice. In a perfect world, you want every open space and every square inch of body surface vibrating with the sound of your voice. That way, you spread the effort around, rather than making your vocal cords do all the work. Not only do you strengthen your voice, you also make it deeper, richer and more expressive.

There’s no reason why you can’t speak all day, in a fairly large room, without losing your voice. You accomplish this by making sure your breath is doing all the work and your entire body is acting as a giant amplifier. In this way, you produce the maximum amount of sound with minimum effort. Your voice easily fills the space without you feeling like you’re yelling. Your listeners are drawn into the experience because you’re fully engaged, fully available and powerfully present.

Voice Training: Tired Vocal Cords

Losing your voice is no fun, and overworked vocal cords make the simplest communication a chore. No one likes dealing with a voice that gets tired, sore and raspy after fifteen minutes of speech. Assuming you’re in good health, the loss of voice is usually due to a lack of breath support, tension or both. Voice training can strengthen your voice and enable you to speak clearly for extended periods of time without losing your voice.
