48 Sounds Masterclass

You understand English. You can read it, follow along with conversations, and you know way more than you can actually say out loud.

But when it's YOUR turn to speak? That's where things break down.

You hesitate before certain words. You avoid others entirely. People ask you to repeat yourself, and you're never quite sure what went wrong.

And here's what makes it worse... every day you practice without knowing the correct sounds, you're reinforcing habits that only get harder to fix.

So you do what everyone does... you go to YouTube. You watch pronunciation videos. "Round your lips." "Drop your jaw." "Push your tongue back." You repeat words over and over and over...

And nothing changes.

Know why?

Because you've been trying to fix your mouth when the real problem is your ears.

Think about it.

If your ears can't hear the difference between two sounds, how is your mouth supposed to choose the right one?

It can't. Your brain is missing the information it needs.

This is why you can repeat a word 50 times and still not sound right. This is why pronunciation videos never seem to stick. They're all focused on what your mouth should do... but they skip the most important step: training your ears to hear what's actually happening.

Almost nobody teaches this. But it's the one thing that actually works.

"For the first time in my life, I can actually distinguish the 'a' and 'e' sounds. It completely changed the way I hear English."

I know because I used the same approach to master Spanish.

When I was learning, no one taught me pronunciation. My university professors didn't cover it. Native speakers couldn't explain how they made the sounds they used so effortlessly. So I had to figure it out on my own.

I trained my ears to hear EVERY sound, learned to catch my own mistakes in real time, and built the ability to self-correct on the spot.

The result? I was born and raised in California, but when I speak Spanish, people regularly think I'm a native speaker.

Not because I have a special gift. Because I discovered the right method: train your ears first, and your mouth follows.

Now I teach that exact method to English learners. And it starts right here.

The 48 Sounds Masterclass

English has exactly 48 distinct sounds. Every word you'll ever say is built from these same 48 building blocks.

If you can hear and produce each one clearly, your pronunciation transforms. If you can't... you'll keep guessing.

In this 2-hour video training, I walk you through every single sound of my American English accent and show you:

  • How to HEAR each sound correctly (the step everyone skips)
  • The micro-movements that produce clear, natural pronunciation (most happen inside your mouth... you can't even see them, but you CAN learn to feel them)
  • How to use sounds from YOUR native language as shortcuts to English sounds
  • Visual demonstrations of exactly what my lips, tongue, and jaw are doing for each sound
  • The practice mistakes that lock in bad habits and make pronunciation worse over time

This isn't another "repeat after me" video. It's a detailed, sound-by-sound breakdown with real examples and real corrections. The kind of training I couldn't find anywhere when I was learning... so I built it myself.

Once Your Ears Are Trained, Everything Changes

You stop avoiding words you're not sure about.

You stop guessing whether you said it right.

When someone asks you to repeat yourself, you know exactly what to adjust... because you can HEAR the difference now.

And every podcast, song, and conversation you listen to becomes training material. Because once your ears know what to listen for, they never stop working.

This is the foundation that makes everything else in English easier.

"This training marked a clear before-and-after moment in my understanding of English pronunciation."

— Alvaro

This Training Is for You If:

  • You've been mispronouncing a word for years and only found out because someone pointed it out
  • You said one word and the person heard a completely different word
  • You can't tell the difference between similar sounds no matter how many times you listen
  • You've watched pronunciation videos online and nothing sticks
  • You want to learn from a real, specific accent (mine: West Coast Californian) instead of generic "standard American English"
  • You want to stop depending on someone else to tell you what you're doing wrong... and learn to hear it yourself

P.S. Think about the last time someone asked you to repeat yourself. Remember that feeling? The confusion on their face. The tightness in your chest. That moment didn't happen because your English is bad. It happened because of ONE sound you can't hear yet. This training costs less than the coffee you'll drink this week. But unlike the coffee, it permanently changes how you hear and speak English. For $19, that moment doesn't have to keep happening.
