AI Voice Coach
Brutal, kind, specific feedback on your voice and pace — in 10 minutes, using any AI you already have.

How it works
1
Record yourself explaining one concept for 2 minutes on your phone.
2
Give the recording (or its transcript) to your AI — ChatGPT, Claude or Gemini — with our coaching prompt.
3
Self-log what it found, get your drill, download your report (PDF).
STEP 1 OF 4
Prepare your 2-minute take
One take. No restarts. Real conditions.
Pick one: the script you wrote in Script Studio (Chapter 4) · your baseline video topic · or simply “explain your day job to a 15-year-old”.
Pre-flight checklist
✓  Quiet room, phone 15–20 cm from your mouth
✓  Stand up — your voice gets 20% more life standing
✓  Glass of water first; dry mouth swallows word endings
✓  One take only. Stumbles are data, not failures.
STEP 2 OF 4
The coaching prompt
Paste this to your AI along with your recording or transcript. Word for word.
You are a strict but kind voice and delivery coach for online teachers, trained on the Codebasics Art of Teaching principles. I will give you a recording (or transcript with timestamps) of me explaining a technical concept for about 2 minutes.

Evaluate ONLY delivery, not content accuracy:

1. PACE - estimate my words per minute. Teaching target: 110-130 WPM. Flag any section where I rush.
2. PAUSES - do I leave real pauses after key ideas, or do I fill every silence?
3. DICTION - do I cut or swallow word endings? List 5 specific words I swallowed, with timestamps if available.
4. FILLER WORDS - count my um/uh/like/basically/actually per minute.
5. ENERGY - does my voice have life, or is it flat? Where does energy drop?
6. STRUCTURE - can a listener tell where I am: opening pain point, explanation, recap?

Output format:
- 3 specific strengths (quote my actual words)
- 3 specific fixes, most important first
- Estimated WPM
- ONE drill I should practice this week (be concrete: what to do, for how many minutes, daily)

Be honest. Do not flatter me. I am training to become a Codebasics Certified Trainer.

STEP 3 OF 4
Run the session
1. Open your AI. If it accepts audio, upload the recording. If not, get a free transcript first (most phones and meet apps transcribe) and paste that.
2. Paste the coaching prompt.
3. Read the feedback twice: once to flinch, once to learn.
What good AI feedback looks like
Strengths: “Your opening - 'imagine your app just crashed at 1 million orders' - lands with real energy” ...
Fixes: “1. You averaged ~168 WPM - a sprint, not a lesson. 2. The endings of 'processing', 'streaming' and 'partitioning' disappear. 3. Eleven 'basically's in two minutes.”
Drill: “Read one paragraph aloud daily for 7 days at deliberately HALF your natural speed, over-articulating every word ending. 5 minutes a day.”
STEP 4 OF 4
Log what the AI found
Translate its feedback into an honest self-rating.
Pace — Was your WPM in the 110–130 teaching zone?
Diction & word endings — Did endings survive? (-ing, -ed, -tion)
Filler words — Um / uh / basically per minute
Energy — Alive voice, or flatline?
Structure — Could a listener tell where they were?
YOUR RESULT
– / 20
Complete the steps above
(If the buttons are not interactive in your LMS view, score yourself using the reveals above.)
Your voice is an instrument. Practice is the tuning.
Do your drill daily for one week, then re-record the SAME 2 minutes and run the coach again. That before/after is exactly what your Stage 1 evaluators want to see.
