Free AI Pronunciation Grader & Speech Shadowing: Practice Speaking with Instant Mic Feedback

When we listen passively, our brains fill in the gaps without forcing our physical articulators to move. Native speech flows with connected speech phenomena—linking words together (*"pick it up"* $ ightarrow$ *"pi-ki-tup"*), dropping plosive stops, and softening "t" sounds into flaps.

Without actively exercising these sound combinations out loud, non-native speakers default to the physical motor habits of their mother tongue. Speech shadowing—the technique of repeating authentic native sentences at speed—builds the exact motor pathways needed for smooth, effortless speech.

SayItVid's speech grader utilizes real-time speech recognition directly in your browser:

1. 1Listen: Play the video snippet to hear how a native speaker phrases the target sentence.
2. 2Record: Click the red Start Recording button and speak into your microphone.
3. 3Score: The algorithm compares your acoustic phoneme sequence against the verified transcript and computes an accuracy score from 0% to 100%:

• 90% – 100% (Native Cadence): Unlocks an animated green completion badge with sparkles.
• 70% – 89% (Solid Intelligibility): Indicates minor dropped sounds or slight pronunciation variations.
• Under 70% (Practice Needed): Prompts you to review the transcript and retry.

A general score alone does not teach you what to fix. SayItVid renders word-by-word chromatic feedback:

• Green Words: Pronounced with crisp accuracy and correctly recognized.
• Red Words: Flagged for missed consonants, wrong vowel qualities, or dropped syllables.

For example, if you shadow the sentence *"The entrepreneur delivered a particularly impressive keynote"*, and the word *"particularly"* turns red, you can immediately identify your articulatory stumbling block and practice that specific word before attempting the full sentence again.

One of the greatest challenges in pronunciation training is the "inner ear illusion"—we perceive our own voice resonating through our skull bones, which sounds vastly different from what external listeners hear.

SayItVid's Mirror Audio Player gives you instant auditory truth:

• Tap Play Native to hear the YouTube speaker.
• Tap Play Your Recording to hear your microphone capture.

Toggling back and forth between the two clips makes differences in intonation, vowel length, and stress immediately apparent.

You can integrate speech shadowing into your routine through two convenient entry points:

• The Dedicated Speech Hub ([/shadowing](/shadowing)): Access hand-curated exercises categorized by difficulty—from everyday conversational greetings to advanced technical terminology and business negotiations.
• On Every Word Search Page: Whenever you search a word on SayItVid (e.g., /pronounce/comfortable), the interactive speech shadowing card is built directly into the video player screen, allowing you to shadow real video clips of that word on demand.

To achieve measurable fluency gains within 30 days, follow this high-intensity 15-minute routine every morning:

• Minutes 0–3: Choose 2 sentences on the Shadowing Hub. Listen 3 times with closed eyes to focus entirely on pitch contour and tempo.
• Minutes 3–7: Mouth the words silently in sync with the native speaker (silent shadowing).
• Minutes 7–12: Turn on your microphone, record your voice, and repeat each sentence until your AI score reaches $\ge 90\%$.
• Minutes 12–15: Play back your mirror audio and compare your vowel endings to the native speaker.

For maximum scoring accuracy:

• Wear Headphones: Using headphones prevents the video sound from echoing back into your microphone, preventing false transcription errors.
• Position Your Mic Appropriately: Keep your microphone 2 to 3 inches away from your mouth to avoid harsh plosive "popping" on letters like P and B.
• Browser Permissions: Ensure you click "Allow" when your browser requests microphone access. Your voice is analyzed locally and never saved or shared without your permission.
