How American Voice Clarity Lab Evaluates Your Call
ITU-T G.711 Acoustic Cutoff (Why Phone Calls Sound Harder Than Zoom)
Standard PSTN telephone networks filter out all audio frequencies below 300Hz and above 3,400Hz. Because English fricative consonants ('s', 'f', 'v', 'th') carry their distinguishing acoustic energy between 4,000Hz and 8,000Hz, phone callers must rely on phonetic words and cadence.
Scenario Preparation & Simulator FAQ
Should I use NATO phonetics (Alpha, Bravo) or everyday American names (Apple, Boy)?
Both are universally understood by US operators—NATO phonetics (Victor, Bravo, Delta, November) or standard American telephone words (Mary, Nancy, Sam, Frank) work equally well.
