How to Use Your Breath to Give Your Voice a Boost When Presenting/Public Speaking

You may well have experienced a presenter droning on monotonously, and you’ll know how hard that is to listen to.

The key to an attractive, dynamic speaking voice lies in breathing – or more precisely, in finding a depth in our breathing so that our voices are nourished by a steady flow of breath as we speak.

Let me share some tips about breath and posture that will help you find your true voice. Find a calm place where you can focus and feel comfortable when trying out the exercises.

If you have physical issues, a bad back or neck for example, tackle the exercises in the way that’s safe.

Setting the scene

Posture counts for a lot. Whether standing or seated, we need to create the best conditions to take a breath.

So how do you stand? Your feet should be no more than shoulder width apart, firmly feeling the ground. Align your posture so you can imagine a line proceeding up your legs, continuing up your spine. Your shoulders are chalk and relaxed, hands and arms comfortably by your sides. You can imagine your head crowning your body.

You should feel springy, active, alert – ready to speak.

‘Low rib’ breathing

Maintaining your good, flexible posture place your thumb under your lowest rib at the side of your rib cage, shoulders are still back and relaxed. Gently and slowly take a deep breath through your nose, feel a slight expansion at the rib cage. Then calmly breathe out.

This kind of breathing is the opposite of the shallow, high in the chest breath many people use in everyday conversation.

It is good for speakers to have easy access to drinking water because your vocal folds (or vocal cords as they used to be called) only work well when you are hydrated.

Practicing extending your breath

Take a low breath, then in your mind count to 5 slowly breathing out gradually: 1 2 3 4 5!

Rest for a moment, then take your ‘low rib’ breath and breathe out counting slowly in your mind to 6 this time.

You can continue all the way up to 10 or eventually beyond. But remember only 1 or 2 minutes of this type of exercise at a time before taking a pause (you don’t want to get light-headed).

If you continue this exercise over time your body will accustom itself to a more settled, longer span of breathing out. You need this gentle, flowing span of breath to sustain a fine quality in your voice when speaking. 

A bonus is that if you are feeling nervous before a speaking presentation of any kind, be it an online call with clients or perhaps a formal or social occasion speech, you will only need to focus on your breathing like this to remind your body of the healthy breathing reflex you have established with the exercise. This has the effect of reassuring you and making you appear poised to your audience.

Transforming breath into speech

Now that you have established a good posture and breath it is time to transform that breath into words and expression. You can extend your breath span so that even longer sentences can be delivered comfortably without a feeling of running out of breath.

Here is a warmup routine using your settled, flowing breath.

Firstly, set up your good posture, take a low breath and hum a tune. I tend to use ‘Happy Birthday to You’. 

At first breathe at the end of lines as you need to, but gradually try to do the first two lines ‘Happy Birthday to you, happy birthday to you’ in one breath.

Now do it again, maintain good, poised posture and ‘low rib’ breath. Sing it out loud with the words – it doesn’t matter whether you think you sing well or not. This is about warming up our voice for speaking and using that breath.

Alternatively, there are many word rhymes or tongue twisters(look online) that you can use in a warmup as you steady your breath flow and extend your vocal range. This example has a great range of vowels and consonants, too. Master it steadily line by line. Allow the pitch of your voice to rise or fall naturally with the meaning of the words.

Does the man in the moon like music?

Does he tootle on his flute, or does he croon?

Does he slip in something lunar in the way he plays his tune?

Or does he simply sit and doodle on the moon?

Finally say the first few lines of your speech once or twice, out loud. 

With this preparation you be ready for your speaking challenge and be fully able to create a relationship with your audience members as you share your message with them.
