Diagnostics · what we measure

We don't grade fluency.
We count the things you can actually point at.

No 9.2-out-of-10 fluency scores. No badges that fake progress. Five things we actually measure, and five things we deliberately don't — because they would lie to you.

The five we count

Five real metrics. Defendable, comparable, yours.

Most speaking apps give you a fluency score because it looks like proof. It isn't. These five things are measurable, comparable across sessions, and you can defend them. So we count these.

Count
Filler word frequency

“Um”, “uh”, “basically”, “actually”, “like”, “you know”. Counted per 60 seconds of speech.

Why this
Lower count usually means more in-control speech.
Time
Pause length after a question

The time between when a question ends and when your answer begins.

Why this
Long pauses suggest the freeze pattern. We track the trend, not the moment.
Count
Words per minute

Native-comfortable speed for English sits at 120–160 WPM. We measure yours per session.

Why this
Too fast usually means anxiety. Too slow usually means searching for words.
Structure
Answer structure detection

Did you open with the point? Did you close cleanly? Was there a recoverable middle?

Why this
A structured answer is recallable. A rambly one isn't.
Continuity
Same task, two weeks apart

The benchmark. We give you the same prompt, record both takes, show you side by side.

Why this
This is the only honest measure of “did practice work”.
Five numbers we refuse to give

Five numbers we refuse to give you.

Won't
A single “Fluency Score”
Fluency is multi-dimensional. A number averages those dimensions until it loses meaning. We show the dimensions.
Won't
Vocabulary size
Counting how many rare words you used doesn't tell us if you said the right thing. Easier words said better is more useful.
Won't
Grammar correctness
We're not grading you. Indian English has its own grammar that is perfectly valid. We coach for being understood, not for matching a textbook.
Won't
Pronunciation against US / UK
Your accent isn't a problem. Being unclear is. We measure clarity, not accent-match.
Won't
Streaks
Streaks pressure you on bad days. The whole point of this app is to lower the pressure, not add a new one.
The benchmark

The benchmark is the whole game.

One short task. Same wording. Recorded once today, once in seven days, once in thirty. Side by side. Whatever changed is what changed. No averaged score is going to argue with the recording.

Week 1 · “your standup”Week 2 · same prompt

So, um, yesterday I was kind of working on the activation flow, and basically…

Take 2
Yesterday I worked on the activation flow. Today I will continue with the same thing.

Illustrative example. In the app you record both takes yourself; they play back side-by-side on the same screen.
