Fluent Forever Review: How to master language fluency

In his book Fluent Forever: How to Learn Any Language Fast and Never Forget It, Gabriel Wyner proposes his solution to achieving fluency in the language of your choice. The book and the theory behind it is inspired by Wyner’s work as an opera singer, for which he was required to master the pronunciation of multiple languages.

I learned about this book over this past summer. I was just beginning to organize my routine for learning and mastering Danish. Therefore, I began scouring the Internet for strategies and routines that I could schedule around my work and other responsibilities. Then, I came across a couple of YouTube videos discussing the book. I only skimmed them briefly, learning the term Spaced Repetition (see below) and about the use of memorization to master a language. Eventually, after coming across a copy on my own in one of my favourite indie bookstores, I decided to have a look for myself and see what Wyner is talking about.

Summary of Fluent Forever

Wyner’s thesis is that memorization is a key tenet to mastering a language. He proposes the Spaced Repetition System (SRS) as an important strategy to achieve this. SRS is a flashcard-based learning strategy. After studying each flashcard, your recall determines how often you revisit a given card. If you are incorrect, you revisit the concept immediately. If you are correct, Anki pushes it back so you revisit it later. Each time you correctly recall a concept, Anki pushes the corresponding flashcard further back, so that the times between each review become longer and longer. You may not revisit a concept for days, weeks, or months, even.

In the book, Wyner focusses on three aspects of language to study using SRS: sounds, words, and sentences. Before studying words and sentences, you must master the sounds of a language. In the text, he goes over the importance of mastering the sounds of a language to achieve proper pronunciation, especially for sounds which do not exist in your first language.

Wyner offers study methods for pronunciation, words, and sentence structure focussing on SRS. In the Gallery, he illustrates the kinds of flashcards you can make to study each aspect. For each aspect, Wyner gives multiple flashcard styles to use. He incorporates audio recordings and images into the flashcards. The audio recordings make sure the learner has access to proper pronunciations of each sound/word/phrase. Including images allows the learner to acquire the word in the target language without translating it through their native tongue.

(NOTE: You can only include audio recordings in your flashcards if you are building them on a digital software such as Anki)

How Fluent Forever fits in 2025

Fluent Forever was published in 2013 and, at the time of writing, no new editions have since been released. Therefore, Wyner discusses some Internet- and digital-technology-based components that are now out-dated. For instance, Wyner describes how to use the “Switch to Basic Version” function on Google Images to provide basic captions to translate into your target language. In my own investigation, I could not find a “Switch to Basic Version” option to select on Google Images.

Some of the digital aids Wyner discusses in the book are Anki (the flashcard program), Forvo.com (a website featuring .mp3 recordings of words and phrases in different languages), and Google Images (see above). Anki and Forvo.com have both gone through updates since Fluent Forever was first published, but in my experience, at least, these updates do not impact how Wyner proposes to use them. Anki still follows SRS in its revision methodology. You can incorporate images and recordings into your flashcards on it as part of your learning practice. The desktop and Android applications for Anki are free to use. If you want to download the mobile app for iPhone, you must pay $25USD ($34CAD for my fellow Canadians).

Forvo.com allows users to listen to .mp3 recordings of words and phrases in different languages. It has recordings in over 430 languages to date. If you have an account, you can download .mp3 files to your desktop. Forvo.com is completely free to use.

Language learning apps

A technology that Wyner does not mention in Fluent Forever is language-learning software. Nowadays, you can’t move without hearing about Duolingo or getting an ad for Babbel. However, these apps were either not in existence or still very new at the time of publishing. Duolingo was launched in 2012. Babbel was founded in 2007 and its website was launched in 2008. Rosetta Stone, which Wyner does briefly mention in the book, was first released in 1992.

An updated edition of Fluent Forever would have to mention language learning apps as Wyner has since launched an app of the same name. Fluent Forever App is available to learn 12 languages using the method Wyner put forth in the book.

Thoughts on Fluent Forever

When it comes to the methodology Wyner proposes in Fluent Forever, I have some thoughts.

Pronunciation mastery

I studied linguistics and thus am familiar with the International Phonetic Alphabet, which Wyner incorporates in his discussion of pronunciation mastery. Therefore, I understand from an academic perspective the importance of understanding and being able to produce the sounds of the language you are learning. However, the IPA is not the most accessible means of learning a language’s sounds to the average laymen. That is unless you take the time to study the IPA on its own. I myself struggle to understand the IPA when I come across it two years after exiting my Master’s program.

Flashcards and SRS

I enjoy the SRS as a method of studying. I have even begun incorporating Anki flashcards into my daily language study. However, Wyner proposes a system of composing flashcards which is very time-consuming. This is especially true for creating flashcards with Anki or some other digital flashcard software. I work a part-time job and even I do not have time to search for images, download .mp3 files of audio, and compile all of that content into multiple flashcards per topic.

Incorporating other learning/teaching materials

Another issue I find with Wyner’s methodology is that existing language knowledge and other study sources (ex. classes, grammar books, etc.) are not well-incorporated into it. While he does mention grammar books and language classes explicitly throughout the book, I struggled to find any concrete advice on how to work Wyner’s approach into those components, or vice versa.

I am currently studying Danish primarily using the book Complete Danish. This book regularly introduces new vocabulary concepts to the learner. These concepts are not just single words, but short phrases and full sentences as well. Some of the single word vocabulary can be treated with the flashcard strategy Wyner proposes, but the same cannot be said for the phrases and sentences. I cannot study these sentences without knowing the English translation, which violates Wyner’s tenet of no translation.

Final notes

In general, I found Fluent Forever to be an interesting read. Wyner offers good strategies to acquire a language–although I disagree that carrying out those strategies can be achieved realistically. Like I said above, I have even begun incorporating SRS and Anki flashcards into my regular language study. However, I am not exactly following the approach Wyner proposes here.

I recommend the book to anyone who wants to learn a language or has begun learning a language and would like additional information to supplement existing learning strategies.
