How to Be Understood on Phone and Video Calls

Calls strip away lip-reading and body language, so clear speech matters more. A few habits make you far easier to understand on the phone and video. Here's how.

Slow down and articulate

Without visual cues, listeners rely entirely on your sound. Slow slightly, articulate key words clearly, and pause between phrases. What feels a touch slow to you is just right on a call.

Nail names and numbers

Names, numbers, and email addresses are where calls go wrong. Slow right down for these, spell out when useful, and confirm: 'That's fifteen — one-five.' A little extra care prevents costly mix-ups.

Use good audio

Half of being understood is being heard clearly. Use a decent headset or mic, a quiet space, and a stable connection. Great pronunciation is wasted through a bad connection — the basics matter.
