Stress:
“UN-doubt-ed-ly, this is true.”
“It is es-SEN-tial that we act.”

Smooth linking:
“for this reason…” → “for-this-REE-zun”
“from my perspective…” → “frum-my-per-SPEK-tiv”

Speaking practice:
“Clearly, we need a better solution.”
“Undoubtedly, education shapes the future.”
“From my perspective, this approach is effective.”
