What Are Accents Anyway?

Our experts believe that most accents can be described with three parameters:

icon for duration of sounds

Duration of sounds

icon for vocal intonation

Vocal intonation

icon for articulation quality

Articulation quality

How to make your pronunciation clear? We believe that the answer is in becoming aware of your individual assumptions and tendencies in pronunciation and, then, having enough practice to start using the right pronunciation unconsciously.

Accent Hero uses modern speech recognition technology to provide you with feedback in real time, showing tips and comparing your pronunciation to the pronunciation of a native U.S. English speaker.

Accent Hero presents results visually, which helps to see the difference even if you don’t have an ear for music. Moreover, we’ll show you a reference transcription, just in case, if you're wondering what dictionaries say is the right way.

Evaluate Your Progress

Accent Hero uses two types of assessments to supplement your learning: assessments by people and feedback from the technology. Together they create a hybrid system with benefits of each of them and the drawbacks of none.

Fail

Hard to comprehend

Fair

Understandable, but a lot of room for improvement

Good

Clear and easy to understand

Great

Like a native

What Our Users Say?

Feedback from our users.

Elena

I'd been using Acccent Hero for two months before I relocated to the U.S. and enrolled into an ESL course in California. To my suprise, the teachers were referencing my pronunciation as the best in my class.

Alex

I'm an engineer. Until I've found Accent Hero with its visual feedback, I wasn't able to understand why people were complaining that it's hard to understand what I say. Seeing the mistakes and being able to correct them in real time was a huge boost to my communication skills!

Paul

Before I started using Accent Hero, I didn't realize that English has 15 vowel sounds despite only 5 vowel letters! Now, I not only know the sounds but can comfortably use them in any word.

Margo

I am a music teacher, and I love the ability to see the pitch chart and compare my vocal intonations to those of a native speaker!

About our technology and its limitations.

The accuracy of acoustic analysis depends on the level of noise in your surrounding environment. If you keep getting inconsistent results, please try practicing using a microphone headset and in a quieter room.

The service uses statistical models to find and distinguish phonemes, guess stressed syllables, etc. As we rely on statistics, the more data we have on your pronunciation, the more accurate results are.
