Phone sales = voice sales
On the phone, the buyer can't see your posture or your eyes. Every trust signal you have lives in your voice. That's why elite phone closers obsess over voice training the way athletes obsess over technique.
The pre-call voice warm-up (60 seconds)
1. Hum "mmm" for 10 seconds — opens chest voice and drops your default pitch.
2. Roll your jaw and shoulders — releases tension that strangles the voice.
3. Yawn intentionally twice — opens the throat.
4. Read your opener once aloud, slowly — sets the pace.
That's it. Skipping the warm-up is the #1 reason reps sound flat on call #1 of the day.
The 4 voice levers on the phone
- Pitch — slightly lower than conversational. Authority sits in chest voice.
- Pace — 130–150 wpm. Most cold callers run 180+.
- Volume — slightly under what feels normal. Pulls the buyer toward you.
- Inflection — statements fall at the end. Rising = uncertain.
Phone-specific moves
- Smile while talking. Buyers can hear it. Even on cold calls.
- Stand up. Voice carries differently when you're standing — more authority, less monotone.
- Use the buyer's name 2–3 times max. More than that reads as scripted.
- Hold silence after the close. Same 7-second rule as in-person.
On compressed mobile audio
Cell calls strip 30–40% of vocal range. Slow down further than you'd think necessary. The buyer's brain has to work harder on a phone call than a video call.

FAQ
What's the single biggest fix for phone voice?
Slow down. Most cold callers run too fast. Cutting pace by 20% lifts hook rate immediately.
Should I script my opener?
Yes — and memorize it cold. The script frees you to focus on tone.
Do I really need to stand up?
Standing isn't required, but reps who do report better energy on long phone-call days. Try it for a week.

"I never make decisions on the first call."
It's a self-protection script — usually built from a past regret, not this offer.
"My partner handles all the money decisions."
If they truly can't decide alone, you should've had both on the call. Now you fix it.
