Impromptu Speech
Think fast, speak clearly
Get a surprise prompt, organize your points on the fly, and deliver under time pressure like the real event.
Tongue Twisters
Sharpen your diction
Loosen up your mouth muscles with quick reps that target pronunciation, pacing, and ending consonants.
Debate Practice
Practice both sides
Build a case for and against the resolution, work through timed sections, and repeat until your arguments land.
How it works
From cold open to coach's notes in about ninety seconds.
01
Pick a mode
Start with SPAR Debate, Impromptu Speech, Debate Practice, Casual Speech, or Tongue Twisters — Congressional Debate is on the way.
02

03
Get coached
Review score, pace, filler words, and a short coach's note while the last attempt is still fresh in your head.
AI feedback that feels human
A coach who listens to every rep and tells you what to try next.
VoxStar is strongest when you want specific, repeatable feedback without waiting for the next team practice. The notes stay short, warm, and actionable.
-
A score out of 10 every rep Each session lands on a 1–10 score so you can see whether your last attempt was your best one yet.
-
Pace and filler words, measured VoxStar checks your words-per-minute and counts filler words like "um" and "like" so you know exactly what to tighten.
-
History and weekly trends Saved sessions, a best-score-by-mode view, and an average-score-per-week trend show whether you're actually getting better.

FAQ

After every rep you get a 1–10 score, your speaking pace in words per minute, a count of filler words like "um" and "like", and a short coach's note on what to try next. History stores past sessions so you can watch your weekly average move.
