Delivering a persuasive keynote, sales proposal, or educational seminar requires more than beautiful slide design; it demands confident vocal pacing, clear enunciation, and natural presentation delivery. However, rehearsing solo in front of a mirror or asking colleagues for repetitive dry runs can be inconvenient. In Microsoft PowerPoint, Speaker Coach (also known as Rehearse with Coach) uses artificial intelligence to evaluate your spoken presentation in real time and deliver structured, objective coaching feedback.
Available in PowerPoint for the web, Windows, macOS, and mobile, Speaker Coach listens to your speech via your microphone while you advance through your slides. As you speak, it provides on-screen prompts warning you if you are talking too quickly, relying excessively on filler words (like “um” and “basically”), reading slide bullet points verbatim, using insensitive language, or speaking in a flat monotone pitch. After your rehearsal, it generates an extensive Rehearsal Report card. In this guide, you will learn how to launch Speaker Coach in PowerPoint, interpret real-time prompts, and analyse your post-session metrics.
What Does Speaker Coach Evaluate?
Speaker Coach analyses core dimensions of verbal communication using neural speech processing:
- Pacing (Words per Minute): Measures speaking speed and alerts you if your pace exceeds 160 words per minute (too fast) or falls below 100 words per minute (too slow).
- Filler Words: Detects repetitive hesitation sounds such as “um”, “ah”, “like”, “you know”, and “basically”.
- Pitch & Monotone Delivery: Evaluates tonal variation and warns you if your voice sounds unenthusiastic or flat.
- Originality (Reading from Slides): Detects when you read slide text word-for-word rather than elaborating conversationally.
- Inclusivity & Sensitive Language: Flags non-inclusive terminology, culturally insensitive phrases, profanity, or outdated industry idioms.
- Repetitive Language: Highlights frequently repeated phrases to help you diversify vocabulary.
System and Account Requirements
To use Speaker Coach in PowerPoint, verify these setup details:
- Platforms: PowerPoint for the Web (free with a Microsoft Account), PowerPoint on Microsoft 365 for Windows, macOS, iOS, and Android.
- Microphone: An active internal or external microphone connected to your computer.
- Language Support: Optimised for English (US, UK, and international dialects), with expanding support for French, German, Spanish, and Japanese.
- Internet Connection: Requires active cloud connectivity to stream speech telemetry to Microsoft speech analysis services.
How to Start Rehearsing with Speaker Coach
Launching a rehearsal session takes only a few clicks:
- Open your presentation deck in Microsoft PowerPoint.
- Click the Slide Show tab on the ribbon.
- In the Rehearse group, click Rehearse with Coach.
- Your presentation opens in full-screen slide show mode.
- A small dialogue box appears in the lower-right corner displaying a microphone icon.
- Check the box labelled Show real-time feedback if you wish to see prompts pop up during your speech.
- Click Start Rehearsing.
- Begin speaking aloud into your microphone as you advance through your slides using the arrow keys or spacebar.
Interpreting Real-Time Coaching Prompts
While you rehearse, Speaker Coach generates unobtrusive toast notifications in the bottom-right corner:
| Prompt Notification | Meaning & Recommended Adjustment |
|---|---|
| “Try speaking a bit slower” | Your pace exceeded 160 wpm. Take a breath and pause between key concepts. |
| “Try to avoid filler words” | You used hesitation sounds like “um” or “like”. Replace fillers with silent pauses. |
| “Try not to read the slide” | You spoke text that matches the on-screen bullet points verbatim. Paraphrase ideas. |
| “Vary your pitch to keep audience engaged” | Your tone has remained flat for several sentences. Inflect key words for emphasis. |
| “Consider using more inclusive phrasing” | Suggests alternative neutral phrases (e.g., “workforce” instead of “manpower”). |
Analysing the Rehearsal Report Card
When you finish your dry run, press Esc or click the pause button and close the slide show. PowerPoint immediately renders a comprehensive Rehearsal Report:
- Summary Stats: Displays total elapsed rehearsal time and total slides covered.
- Pacing Graph: A line chart mapping your words-per-minute rate across each slide, highlighting areas where you spoke too quickly or too slowly.
- Filler Words Log: Lists exact filler words uttered alongside the frequency count.
- Originality Gauge: Identifies specific slide numbers where you read paragraphs verbatim and suggests talking point expansions.
- Pitch Variance: Evaluates high, low, and average tonal inflection curves.
- Click Rehearse Again to reset metrics and run another dry run, or take a screenshot to track your improvements over time.
Tips for Getting the Most Out of Speaker Coach
To turn Speaker Coach into an indispensable presentation prep tool:
- Use a Good Microphone: Rehearse using a dedicated headset or USB desk microphone in a quiet room to prevent ambient background noise from triggering false filler word detections.
- Do Not Stare at the Prompts: Keep your eyes focused on your virtual camera or audience focal point; glance at the coach notifications only briefly to adjust pace.
- Embrace Intentional Pauses: Instead of saying “um” while transitioning between slides, practice remaining completely silent for two seconds; audiences interpret pauses as thoughtful confidence.
