Lammy Index out of 100: fluency 50 and content 50. Fluency: start 15, clean speech (filler words and repeats) 15, pauses 10, pace 10 — based on the Tavakoli & Skehan fluency model. Content: structure 20, coherence 12, answering the question 10, word choice 8 — based on the PSCR rubric (Schreiber et al., 2012). If you practiced without a structure, content is scored on the other three and still weighs 50. If the speech is incoherent or off topic, the whole index goes down: fluent words without a point won't get a high score. If you spoke for less than half the time, the index is reduced proportionally (in Toastmasters Table Topics an answer that is too short doesn't count at all). Pace follows norms for English speech: 130–160 words per minute in conversation, 120–150 in a talk. Levels: 85–100 composed speech, 70–84 confident answer, 50–69 solid base, 30–49 developing, below 30 getting started. The bar shows the score of take 2.

Allow access when your browser asks. Audio is only used to recognize your speech and is never stored.
Say out loud: “one, two, three”. Quietly or with headphones is fine.
You see the difference between just two takes. One session takes 3–5 minutes.
Um, so I'm, uh, a sales manager. Five years in distribution, you know, I kind of handle key accounts. Um, last year I grew sales by a third, basically through new retail chains. I mean, I want to keep growing.
Filler words get highlighted in the transcript automatically — just like in the feedback after your take.
Illustrative example. Take 2 comes right after the feedback, with one task from the coach.
You can know dozens of rules and still freeze when your manager suddenly asks, “What do you think?” That's why Lammy has almost no theory.
Other apps end the session with analysis. Lammy starts with it.
The coach picks one thing you can fix right now. You answer again and see the difference in numbers right away.
Each one is highlighted in the transcript and counted per minute. In a week you start hearing them yourself.
Yes. Practice and coach feedback are free.
No. You can do your first session right away. Signing in with Google or email is only needed to save your progress and streak.
A score from 0 to 100 built from eight metrics: how fast you started, filler words, long pauses, pace, structure, coherence, answering the question and word choice. Fluency and content weigh the same, and smooth speech with no real point won't get a high score. The method is based on research on speech fluency and public speaking assessment. Levels: 85–100 composed speech, 70–84 confident answer, 50–69 solid base, 30–49 developing, below 30 getting started.
No. Audio of your take is only used to recognize your speech: it's deleted right after, we don't store it. The text goes to the coach for feedback. If you're signed in, the transcripts of your takes are saved in your practice history so you can reread them. You can delete them in your account.
