Mastering Conversations with AI: How to Improve Your English Fluency Naturally

The Quest for the Perfect AI Conversation Partner

Ever since ChatGPT’s Advanced Voice Mode launched, I’ve been on a mission; where’s the competition? Where’s the AI that can simulate a real, natural conversation to help me practice English, refine my speaking skills, and get real-time feedback?

Google Gemini? Tried it. Wasn’t impressed. It kept forgetting details mid-conversation. (Though I’ve heard updates are coming; stay tuned for a follow-up.)

Then, over the weekend, I stumbled upon Sesame AI: a research project (not a product, not a sponsor) that blew my mind. It wasn’t just smart; it felt human.

So, I decided to test it against ChatGPT : which one delivers a more natural, engaging conversation to help you speak English fluently?

The Experiment: ChatGPT vs. Sesame AI

Meet Miles—Your Quirky, Conversational AI Friend

I fired up Sesame AI and chose Miles as my conversation partner.

• Me: “Hey, I just moved to the U.S. and feel disoriented. How do I meet people?”
• Miles: “Ah, a fresh start in a new country. That’s a big leap. Sometimes the best way to get your bearings is to just hop in and see what’s what.”
• Me: “What does ‘hop in and see what’s what’ mean?”
• Miles: “My bad; that was vague. What are you into? Coffee? Books? Sunshine?”
• Me: “All three, actually.”
• Miles: “Perfect! Coffee shops, bookstores, parks—those are built-in conversation starters. Next time you’re at a bookstore, strike up a chat with someone browsing the same shelf.”

“Then, we role played a bookstore scenario; Miles suggested playful openers like:

• “Those philosophers aren’t light reading; tackling consciousness today?”

It felt organic, spontaneous, and real; like talking to a funny, slightly awkward friend.

ChatGPT: Helpful, But… Robotic

Same question to ChatGPT:

• “Join local clubs, attend networking events.”

Fine advice, but dry.

Then, I asked for a bookstore conversation starter:

• “Hey, I noticed you’re checking out Bergson. Have you read much of his work?”

It was logical, but stiff, like reading from a self-help book.

The Verdict: Which AI Wins for English Practice?

Criteria	Sesame AI	ChatGPT
Conversational Flow	Feels human, quirky, natural	Structured, slightly robotic
Practical Advice	Same core tips, but delivered conversationally	Direct, but less engaging
Language Feedback	Minimal (research project)	Detailed, corrective
Use Case	Casual, immersive practice	Structured learning & feedback

Sesame AI wins for realism, it’s the closest I’ve felt to a natural conversation. But ChatGPT is better for corrections and structured learning.

A Personal Story: How AI Helped Me Overcome Social Anxiety

One of our Word-Flux team members (who prefers to stay anonymous) shared this:

“When I first moved abroad, I was terrified of speaking. My accent felt heavy, my sentences clumsy. Then I started using AI conversation simulators, roleplaying job interviews, small talk, even arguments. Slowly, my confidence grew. Now, I can walk into a room and speak without overthinking.”

That’s the power of deliberate practice, whether with AI or real people.

Actionable Tips to Improve Your English Conversations
