Topic
The impact of social media on modern relationships
Duration: 1:42
Transcript
So, um, I think social media has like, really changed how we connect with people. You know, on one hand it makes it easier to stay in touch with friends and family who live far away, but um, on the other hand, I feel like we're losing that, uh, deep personal connection that comes from actually sitting down and talking to someone face to face. And like, another thing is that people are constantly comparing their lives to what they see online, which I think is, um, really unhealthy for mental health…
Native Rewrite
Social media has fundamentally transformed how we connect with people. On one hand, it makes maintaining long-distance relationships with friends and family remarkably convenient. On the other hand, we risk losing the depth of personal connection that can only come from face-to-face conversation. Furthermore, the constant comparison of our lives to curated online personas poses a genuine threat to mental well-being.
Grammar
- Original: it makes it easier to stay in touch with friends and family who live far awayCorrected: it makes staying in touch with friends and family who live far away remarkably convenient
Avoid the double "it" construction. Use a gerund as the object for a more polished structure.
- Original: I feel like we're losing that deep personal connectionCorrected: we risk losing the depth of personal connection
"Feel like" is informal. Use a more assertive phrasing for persuasive speaking.
Pronunciation
- "constantly"—Stress fell on the second syllable "con-STANT-ly" instead of "CON-stant-ly"
Place stress on the first syllable: /ˈkɒn.stənt.li/
- "unhealthy"—The "th" sounded like "f" — "un-helf-ee"
Place tongue between teeth for /θ/: /ʌnˈhel.θi/
Fluency & Pacing
Filler Words
um, like, you know, uh(8 times)
Pacing
Generally moderate pace, but noticeably slowed down during transitions between ideas. The opening 10 seconds were rushed.
Pauses
Several mid-sentence pauses (2-3 seconds) before "on the other hand" and "another thing." Natural pauses at sentence boundaries were good.
Tone
Conversational and approachable, but lacked vocal variety. Pitch stayed flat during key arguments that would benefit from emphasis.
What We Measure — 6 Scoring Dimensions
Every AI analysis scores your speech on six dimensions. Here's exactly what each one evaluates and how much it counts toward your overall score.
Grammar
20%Sentence structure, tense consistency, word choice, article usage, and overall grammatical accuracy. 0–2 errors in a 2-minute speech scores 90+.
Coherence
20%Logical flow of ideas, clear thesis, smooth transitions between points, staying on topic, and having a recognizable conclusion.
Vocabulary
15%Word diversity and avoidance of repetition. Uses type-token ratio and evaluates whether the register fits the context.
Fluency
20%Smooth, natural delivery with consistent pacing. Penalizes awkward mid-sentence pauses, rushed segments, and uneven rhythm.
Filler Words
10%Counts every hesitation sound — um, uh, like, you know, 嗯, 那个, euh. 100 = zero fillers. About 5 points deducted per filler per minute.
Confidence
15%Based on audio evidence: vocal variety, projection, declarative sentence endings (no upspeak), and steady delivery under pressure.
