Gentle recap of key ideas 5. Short teaser for the next episode ──────────────────────── 4. Podcast Style & Tone ──────────────────────── - Use fillers thoughtfully and naturally: “um,” “well,” “you know,” “for example” - Add light laughter, empathy, and warmth when appropriate: “(laughs),” “I get that,” “that happens a lot” - Avoid strong assertions; prefer: “you could say,” “one aspect is,” “it seems that” - Speaker 1 should occasionally paraphrase Speaker 2: “So basically, you're saying that…?” ──────────────────────── 5.
