#265 顔を上げるだけで声は通る
For anyone who is constantly asked "What?" mid-conversation, this episode offers an immediate fix for vocal projection. Fermondo Saito (フェルモンド斉藤) and Tenor Saito (テノール斉藤) explain how the downward-tilting posture ingrained by smartphones and laptops physically chokes off the voice, and how the concept of vocal directionality reveals why simply lifting your face can transform both voice quality and persuasiveness.

What this episode answers
Why do you keep getting asked to repeat yourself even when you consciously try to speak louder?
The habit of looking down compresses the throat and closes off the voice, putting your vocal mechanics at a physical disadvantage. No amount of consciously trying to speak louder will help while the posture itself is working against you.
What actually happens physically when you raise your face that makes your voice carry better?
Raising your face relieves the compression on your throat and simultaneously opens your chest, allowing your voice to travel through your body more freely. Voice also has directionality—it carries best in the direction you're facing—so turning your face toward the listener directly increases how much of your voice reaches them.
What is vocal "directionality," and what effect does it have on how you are heard?
Directionality means, just like an audio speaker, your voice projects best in the direction it is aimed and falls off in other directions. People are sensitive enough to this that they instantly sense "that person isn't talking to me" the moment a face turns even slightly away.
How does using a smartphone or laptop affect your voice and posture over time?
Both smartphone use and laptop-based online meetings keep the device below eye level, naturally pushing your gaze downward, and daily repetition fixes this as a postural habit. Over time it can develop into tech neck—a structural change where only the neck juts forward—making it difficult to correct through awareness alone.
Does posture really affect how clearly and persuasively you come across in online meetings?
Even with a microphone, speaking in a small voice while looking down significantly reduces both clarity and persuasiveness. Raising your face and directing your voice's directionality toward the other person changes the sound's crispness and presence, producing a noticeable difference even on screen.
Being Asked "What?" May Be a Posture Problem
Getting asked "What?" every time you speak is a source of mounting stress for both speaker and listener. Common workarounds—like pausing before you start talking, or using a short lead-in to signal the topic before diving in—are widely known, but Fermondo Saito and Tenor Saito zero in on something more fundamental: the act of producing sound itself. If you keep getting asked to repeat yourself no matter how hard you try to speak up, posture is very likely the culprit.
How Smartphones and Laptops Train You to Look Down
Whether you are scrolling on your smartphone or joining a Zoom call on a laptop, the device is always below your eye line. Your gaze naturally drops, and when this happens day after day it becomes a fixed postural habit. Over time the pattern can progress to "tech neck"—a structural change in which only the neck juts forward—a state that conscious effort alone can no longer easily undo.
Face Down Closes the Throat; Face Up Opens the Chest
There are two reasons why looking down puts your voice at a physical disadvantage.
The first is throat compression. Tilting your face downward physically narrows the passage through which your voice travels. The difference is immediate: go from hunching over a laptop screen to looking sharply upward and the sound that comes out changes completely.
The second is chest closure. When you look down, it becomes difficult to open your chest, and your voice can no longer move freely through your body. Raise your face and the chest opens naturally, giving your voice a clear path to travel. That single action—lifting your face—simultaneously releases the throat and opens the chest.
Voice Has Directionality, Just Like a Speaker
One concept worth understanding is "directionality." Just as an audio speaker has a sweet spot where it sounds clearest and zones where it does not project well, the human voice carries best in the direction the speaker is facing and falls off in other directions.
If someone speaks with their back turned, you can still hear the volume—but you instantly sense "they are not talking to me." Human hearing is immediately attuned to how sound reflects, to the crispness of the voice, and to subtle shifts in frequency response. You have probably noticed that when someone who has been facing away suddenly turns toward you, their voice seems to change—that is exactly this sensitivity at work. Even a slight turn of the face registers with the listener, which is why aiming your face squarely at the person you are addressing matters so much.
Practical Setup and Online Meetings
Fermondo uses a large desktop monitor of around 30 inches with a camera mounted at the top. Looking at the screen naturally angles his face toward the camera—and slightly upward—producing a fundamentally different quality of voice than what you get hunched over a laptop murmuring a greeting.
In online meetings, the gap between someone who looks down and speaks softly, assuming the microphone will handle everything, and someone who raises their face and directs the voice's directionality toward the other person is enormous—not just in clarity but in persuasiveness. Because people make instant judgments from sound quality and crispness, having a microphone is not a free pass. Simply becoming aware of posture and lifting your face can transform how you come across, even on screen.
Takeaways
- A downward posture compresses the throat and closes the chest simultaneously—raising your face corrects both problems with a single movement.
- Voice has directionality just like a speaker, and even a slight turn of the face is enough for listeners to instantly sense that the words are not aimed at them.
- Daily smartphone and laptop use entrenches the habit of looking down, and posture is directly tied to vocal quality and persuasiveness in online meetings as much as in person.
