Our Story

We wanted it - so we built it.

I've never seen myself as a natural speaker, or someone comfortable approaching people I didn't know. Yet building my last startup, I found myself knocking on strangers' doors, walking up to crowds, or talking on the phone for hours - eager to share my startup with them. Each time a feeling of anxiety would creep up, and cause my body to tense up. Dryness, hoarsenss, and general fatigue were a common end of day experience for me. Finally with the help of Leila Bostic, a professional voice and speech coach, I was able to understand how to breathe deeper, and train my voice just like any other skill. In 2017, Leila and I started building Astound as a way to share voice and speech coaching techniques with everyone, anywhere.

How your voice actually works

Ask any actor, and they'll tell you that you can train train your voice just like any other muscle. That's good news! There are 4 main components to your voice. Knowing these will help you crush your goals of becoming an effective communicator.

1. Your Diaphragm

It's like the motor of your voice, and sits underneath your lungs.

Feel your stomach expand out as you breathe in, and in as you breathe out. That's your diaphragm under the hood

It pumps air throughout your body just like a pair of bellows. And, since speaking is just another form of exhaling...

the better you diaphragm moves the smoother air can flow through your vocal chords. Speaking will feel like smooth sailing.

2. Your Vocal Chords

That brings us to your vocal chords. They produce sound as air moves through them just like a balloon. Thankfully, we're not left with that squeeky sound, but continue to your resonators.

3. Your Resonators

They include your mouth, throat, and chest. Just like in a cave, the more space your voice has to travel inside them, the more it gets amplified.

4. Your Articulators

Last but not least: your articulators. They include your lips and tongue. The more precise they are, the clearer your words become.
