5 Quick Vocal Exercises to Do Before Recording Video
Have you ever sat down to record a video, hit the record button, and immediately started tripping over your words, mumbling, or running out of breath halfway through a sentence?
Just like an athlete wouldn't sprint 100 meters without stretching their legs, you shouldn't record a high-energy script without warming up your voice.
Your voice is a physical instrument. It relies on the coordination of your vocal cords, diaphragm, tongue, lips, and jaw. If you attempt to record "cold," your speech will sound flat, you will stutter, and you will end up doing 20 takes for a simple 60-second TikTok.
In this guide, we share 5 quick vocal and diction exercises that take only 3 minutes to perform but will instantly make your voice sound deeper, clearer, and more authoritative on camera.

1. The Lip Trill / Lip Bubble (The Cord Warmer)
This is the ultimate vocal warm-up used by professional singers, voice actors, and broadcasters worldwide. It gently warms up your vocal cords and relaxes your lips.
How to do it: Relax your lips and blow air through them so that they vibrate together rapidly (producing a sound like a horse or a toy motorboat: "brrrrrrr"*).
- The Upgrade: Slide your pitch up and down (like a siren) while maintaining the lip vibration. Perform this for 30 seconds.
- > [!TIP]
> If your lips won't vibrate, gently place two fingers on your cheeks to push your lips slightly forward and try blowing again.

2. Tongue Twisters for Diction (The Mumble Killer)
To speak clearly at a fast social media pace (150+ Words Per Minute), your tongue and jaw must be highly agile.
The Tongue Workout: Repeat the phrase "Red leather, yellow leather" 5 times rapidly. Focus on articulating the "L" and "Th"* sounds clearly.
The Lip Workout: Repeat the phrase "Peter Piper picked a peck of pickled peppers" 3 times. Focus on the sharp, explosive "P"* sounds (plosives).
- Perform this for 45 seconds. Focus on precision rather than speed.

3. The "Hum" (Resonance and Depth)
If your voice sounds nasal, thin, or lacks authority in your microphone recordings, you need to engage your chest resonators.
How to do it: Close your mouth, relax your jaw, and hum at a comfortable low pitch ("hmmmmmm"*).
- The Check: Place your hand on your chest. You should feel a distinct, warm vibration.
- Perform this for 30 seconds. This naturally lowers your pitch slightly and adds professional resonance to your recordings.

4. The Jaw Stretch / "The Silent Scream" (Tension Release)
Anxious or nervous speakers unconsciously tighten their jaws. A tight jaw restricts your mouth movements, leading to severe mumbling and quiet delivery.
- How to do it: Open your mouth as wide as comfortably possible (forming an "O" shape, like a silent scream). Hold for 5 seconds, then relax.
- The Massage: Place your fingers on your jaw hinges (just below your ears) and massage them in a circular motion to release muscle tension.
- Repeat 3 times.

5. Diaphragmatic Breathing (The Stamina Booster)
Do you find yourself gasping for air in the middle of a sentence when reading a script? This is caused by shallow chest breathing.
- How to do it: Place one hand on your chest and the other on your stomach. Take a deep breath in through your nose. The hand on your stomach should rise, while the hand on your chest remains completely still.
- Perform this 5 times. This trains your body to breathe from your diaphragm, giving you the lung capacity to deliver long sentences with steady power.
