It is believed that the single biggest advantage of learning a foreign language from a native speaker is their superior pronunciation.
as one study writes:
"Native English speaking teachers are the ideal model for language production. Their speech is held up as the gold standard of grammatical correctness and perfect pronunciation."
Nobody is disputing that, a native speaker has the pronunciation of a native speaker, native means highest level, nobody is disagreeing with this statement
You, as an adult learner, need to ask yourself 2 simple questions:
Question 1: Why is it that non-native say non-native English speaking teachers have accents, why do I have a non-native accent, is it because I didn't have a native English speaking teacher?
Why is it that Arnold speaks with a thick German accent, after 50 years living and communicating with native speakers of English.
How about Yoko Ono, 60 years in America, Antonio Banderas, Penelope Cruz, Jackie Chan.
How about Melania Trump, 20 years in America
But forget about non-native speakers of English, how about native speakers of English, why do they speak with an accent?
Liam Neeson, McGregor, Anthony Hopkins, Naomi Watts,
Why didn't they lose their accents???
The fact of the matter is that native accent is virtually unachievable past a certain age, after childhood.
There is a whole chapter on Biological limitations in my book Virtually Native.
The time and money people waste on pronunciation is truly staggering.
The truth of the matter is that: If you can't hear, you can't pronounce. First you need to hear, and then try to pronounce.
Nobody can teach you how to hear, nobody but you.
Only you can teach yourself how to hear sounds like the TH sound for instance.
And if you manage somehow to hear that sound, the TH sound, then why would you need a teacher to tell you how to pronounce it, you should be able to figure it out yourself
Your ear is your best teacher.
In the past, native English-speaking teachers were the main source of proper pronunciation, not anymore, you can get access to all kinds of native speakers on the internet now, for FREE
That is the second question you need to answer:
Should you, the language learner, pay the native speaker to listen to their perfect pronunciation?
The answer is NO.
We have dictionaries for that purpose, FREE online dictionaries that give you both the British and American pronunciation of every single word, for FREE, words and even whole sentences, for FREE
Furthermore we have movies, with native speakers, movies, TED talks, podcasts, with native speakers to listen and copy, for free
The thing is, you need to know how to listen, how to copy, what to look for. You need the right approach, you need a method of how to practice your listening, something no native speaker can give you, about their native language that is.
You know, there was a time when I longed for a native English pronunciation, a proper British accent, what we call Received Pronunciation,
I really wanted to speak like say Hugh Grant or Jeremy Irons.
But now, I would not trade my accent for a million dollars.
My accent is what makes me unique, what makes me different from the sea of native English-speaking teachers on the Internet.
I can teach you how to reach my level, they can’t.
I can teach you how to reach my level, native English-speaking teachers can never teach you how to reach their level, because they a native.
