Speaking: Speaking for Specific Purposes C1 - Lesson 3: Delivering Specialized Academic/Technical Presentations

Speaking: Speaking for Specific Purposes C1

Delivering Specialized Academic/Technical Presentations

Listen to the scenario audio here.

What you will learn: By the end of this lesson, you will be able to adapt complex academic or technical information for a specific audience, using advanced signposting and data commentary to deliver a clear, persuasive, and professional presentation.

The C1 Challenge: Bridging the "Knowledge Gap"

A B2 speaker can *present* data. A C1 speaker can *persuade* with it. Your main challenge is not just knowing your topic, but knowing your **audience**. You must bridge the gap between your expert knowledge and their understanding.

Compare the language used for two different audiences:

🗣️ To EXPERTS (Peers)

"The qPCR analysis revealed a statistically significant (p<0.01) upregulation of the *CYP1A1* gene in the cohort exposed to aromatic hydrocarbons."

🗣️ To NON-EXPERTS (Public)

"To put it simply, we found that exposure to common pollutants... [uses analogy] ...acts like a 'switch', turning on a specific gene that tries to clean the 'poison' out of the body."

Use these phrases to guide your audience through complex information.

1. Advanced Signposting (Guiding)

Tell your audience where you are going.

  • "What I'd like to do now is pivot to the financial implications." ប្តូរទៅ...
  • "This, of course, brings me to my next point: sustainability." នាំខ្ញុំទៅ...
  • "Let's briefly touch upon the methodology before we move on." សូមលើកយក...

2. Data Commentary (Explaining Data)

Don't just read the chart. Tell them what it *means*.

  • "What's striking here is that..." អ្វីដែលគួរអោយចាប់អារម្មណ៍...
  • "This spike strongly suggests that..." បង្ហាញយ៉ាងច្បាស់ថា...
  • "The key takeaway from this graph is..." ចំណុចសំខាន់ពីក្រាហ្វនេះ...

3. Hedging & Precision (Being Accurate)

Be confident, but don't overstate your claims. Use "hedging" language.

  • "This seems to indicate that..." ហាក់ដូចជាបង្ហាញថា...
  • "One potential implication of this is..." ផលប៉ះពាល់មួយ...
  • "The data is largely consistent with..." ស្របទៅនឹង...

Scenario: The "So What?" Factor 💬

A C1 speaker always answers the audience's unspoken question: "So what?" Notice how Dr. Vanna uses Data Commentary.

Audience: Hospital Board (Non-medical, focused on budget)

Dr. Vanna: "...And if you look at this slide, you'll see a 45% reduction in patient re-admission rates for the test group."

Board Member: "That's a nice number, Doctor, but what does that mean for us, practically?"

Dr. Vanna: "A fair question. What's striking here is that this 45% drop isn't just a number—it directly translates to cost savings. The key takeaway is that by investing $10 in this preventative program, we save an estimated $250 per patient in re-admission costs. This strongly suggests the program will pay for itself within six months."

Fluency Tip

🗣️ Chunking Technical Terms

When you have a long, technical phrase, don't try to say it word-by-word. Group the words into "chunks" and say them as one unit. This signals to your audience that it's a single concept.

Don't say: "We analyzed... the... quantitative... polymerase... chain... reaction... data." (Sounds hesitant)

Do say: "We analyzed the... [pause] ...(quantitative-polymerase-chain-reaction)... [pause] ...data." (Sounds confident)

Practice saying "statistically-significant-difference" or "user-acquisition-cost" as single chunks.

Your Mission: The 3-Minute Expert ⭐

Your mission is to find a complex topic you understand and explain it to two different audiences.

  1. Choose a technical or academic topic you know well (e.g., blockchain, the chemical process for making palm sugar, a specific marketing strategy).
  2. Prepare a 3-minute presentation on it.
  3. Record yourself twice:
    • Recording 1 (Expert): Present it as if you are talking to your professor or a colleague. Use all the technical terms you know.
    • Recording 2 (Non-Expert): Present the *same topic* as if you are explaining it to a 10-year-old child or your grandmother. Use simple language, analogies, and the "To put it simply..." phrase.
  4. Listen to both. Notice how your language, signposting, and even your tone change. This is the C1 skill of audience adaptation.
