There's something different about speaking your thoughts out loud. When you type a question, you edit it. You backspace. You rephrase. By the time you hit send, you've already half-answered it yourself.
But when you talk? You stumble. You say "um." You realize mid-sentence that you don't actually understand what you're asking. And that's exactly where learning happens.
Your brain on voice
Speaking activates different parts of your brain than typing. It forces you to process in real-time, without the safety net of a delete key. When Phil asks you a follow-up question, you can't Google the answer first. You have to think.
This is why the best tutors have always been human. Not because they know more than textbooks, but because they can hear the confusion in your voice and adapt.
The interruption advantage
With text, you wait. You type your question. You wait for a response. You read it. You type another question.
With voice, you can interrupt. "Wait, what do you mean by that?" You can ask for clarification the moment you're confused, not three messages later when you've already lost the thread.
Learning isn't linear. Your questions shouldn't be either.
