On Speaking: Being Heard

August 24, 2006

Part of what I like to write about is public speaking; when college is in session, I work as an Oral Comm tutor, and even when I’m not working in that capacity, my ‘oral comm ears’ are always on. Starting today, I’ll try and write a new public speaking post every Wednesday.

Can you hear me in the back?

The topic I’d like to start with is volume – Human 1.0 unfortunately comes unequipped with an automatic volume control, and judging the correct volume (whether using a microphone or not) can make or break a presentation. Today I’ll cover approaches to being heard without a microphone (I’ll hopefully enlist the help of some podcasters when writing the future article about working with microphones).

Microphones can be a great boost to your voice – they can help project it in huge auditoriums, or record it for posterity. Two catches, however: there are situations where the microphone is completely inappropriate (smaller rooms, informal presentations), and microphones cannot make your voice stronger – just louder. Thus, I think any speaker benefits from learning how to handle a microphone-less situation – so when the microphone comes on, it’s a boost rather than a crutch.

Presenting without a microphone, the burden of volume falls entirely on the speaker and the space. I’ve found the best way to approach the situation is to imagine your voice as actual sound waves coming from your body outwards (as many people can attest, I often use somewhat cheesy but, in my humble opinion, effective physical metaphors). Now, find the back of the room – and when you talk, make sure your voice projects not just to the wall, but all the way back too. This is a quick way of adjusting to different room sizes which scales pretty well for medium-sized speaking venues, and I find the visual element of imagining the bouncing waves is helpful.

Now, most speakers I’ve worked with speak too quietly rather than too loudly – only to be told by someone (someone critiquing their rehearsal, or even a rude audience member) to speak louder! which of course works for about two sentences, before they fall back into their not-loud-enough previous tone. When working with this, I’ve found it’s far easier to scale down than it is to scale up, and trying to work upwards will lead to endless frustration. Instead, find a space to make some noise, and go all out – without screaming or shouting, see how strong you can make the sound waves. Now, take it down a notch – and then another. Going from 110% to 100% isn’t so hard; it’s the 70 to 100% jump that really strains. Try arriving a bit early at your venue and seeing if you find the sweet spot by starting a little louder than you’d think, and toning it down until it feels right.

Since we usually don’t spend our time talking at such a loud volume, many times the exercise above runs into a blocking problem – the muscles we use to project are out of practice, and need a day at the gym. If you can, find a friend that sings, and watch how they use their diaphragm as an impulse to their voice. Even if the actual technique is not something that can be captured in a day, if you can internalize the section of the body that the sound is beginning from, you can try to replicate that in volume exercises.

Great, so we’re speaking at the right volume – but staying there ’till the end of the sentence is as important as getting there at the beginning. How many speakers have you heard Start Off Strong only to fade out by the end of the sentence? (apologies for overcute font sizing)

We’re usually dealing with a mountain of cognitive processes while speaking in public – am I standing in the right place? Am I making eye contact? What’s coming up next? How much time do I have left? We tend to trail off for two main reasons: we’re out of breath, and we’re thinking about what’s already coming next. Breathing and pace warrant their own article (to be written, soon) but they have an impact on volume, too. Make sure you’re getting the air you need to start off each sentence, and if you need to recharge halfway through, take that half a second to do so. And while it’s great to have the next phrase in mind as you wrap up the current one, don’t drop the current sentence just because the next one is waiting. You can combine both of these tips into one – if you take a breath right before the crucial sentence-closing turn of phrase, you’ll help drive your point, and do it at a clear volume.

Finally, there are speakers whose volume problems don’t come from projecting incorrectly or using their head voice – instead, it comes from shyness or fear of public speaking (we’ve all heard the “People are more afraid of public speaking than death” line) – I’ll make sure upcoming articles tackle this issue of shyness for the glossophobes out there.

In the meantime, thanks for reading, and please let me know if you find the tips helpful – or if you’ve found they don’t work at all! ‘Till next Wednesday – in the meantime, also make sure to check out the public speaking tips at lifehack.org for some more general tips.

  1. I just want to add some unsolicited endorsement. mikeyk is the best oral communication teacher at Stanford, not only because he’s an amazing person, but because he helped me get a 97 on my presentation in PWR class. And the advice he gave me, which is echoed in this post, will be carried with me for the rest of my life. Thanks, and You rock!
