9 Best AI Translation Software (That You'll Actually Use)

What is AI Translation? 

The term “AI translation” is exactly what it sounds like: the process of using machine learning and natural language processing (NLP) techniques to translate text from one language to another automatically. The goal is to preserve the meaning, context, and tone of the original content.

Sometimes this works really well, and sometimes it really doesn’t. It all depends on the software you use. 

But advancements in artificial intelligence (AI) have made it easier than ever to get reliable translations for all your text-based assets at a low cost. 

How AI Translation works

At the beginning of the AI translation process, colossal amounts of data are fed into the system to help the algorithms absorb patterns, structures, and the essence of language. Without data input, AI couldn’t even translate “bonjour” to “hello!”

Then, deep learning techniques help the models understand the layers of linguistic subtleties and context. Finally, Natural Language Processing (NLP) applies techniques like part-of-speech tagging and syntactic parsing to ensure the meaning of the original text reverberates in every translated sentence.

Use cases for AI Translation 

AI Translation tools can be used for different purposes, including translating websites, marketing materials, customer support tickets, subtitle translations, and even live translations during meetings or events. These tools are particularly useful for companies operating in global markets or working with international partners, as they can help break down language barriers, and help build relationships and facilitate communication.

Recent developments in neural machine translation

Neural machine translation (NMT) is, so far, the most accurate, versatile, and fluent of machine translation tools. It appeared around the middle of the 2010s and has become the best technology for translating languages. 

There are a few things that affect how well a machine can translate languages:

• The type of technology, or 'engine', it uses
• The two languages it's translating between—or language pairs
• How much practice it has had (through training data)
• The kind of text it's translating

Just like a person, the more the machine practices translating certain languages or topics, the better it gets. After enough practice, the NMT can translate quicker, more accurately, and can easily learn to translate new languages. 

Plus, AI translation technologies represented a $328 billion market in 2022, with projections indicating it could reach more than $1.3 trillion by 2029. The future of language translation technology is bright, and emphasizes what a significant opportunity it is for businesses to reduce costs and scale operations. 

Benefits of AI Translation technology

1. Accuracy levels 

Like any technology, AI translations aren’t always perfect and sometimes make errors or mistranslations. This is especially true with idiomatic expressions and cultural nuances, which can stump even the best human translators.

(For example, moosh bokhoradet in Persian literally translates to “a mouse should eat you” but means “little cutie patootie”. Go figure.)

That said, nothing in tech stays still for long. 

AI translation tools have come a long way in recent years and have become increasingly reliable. When Google Translate introduced the NMT model in 2016, it improved accuracy overall by 34%. By 2021, a study by the UCLA Medical Center found that the accuracy of some language translations shot up to 94%, and Google Translate managed to maintain the general meaning in 82.5% of translations.

Just last fall (October 2023) Google launched Deep Aligner, a novel deep learning model for learning languages that has reduced the average translation error rate from 25% to 5%. And they’re only getting better as the market grows.

2. The speed of AI Translation

Gone are the days of poring over dictionaries and waiting for human translators to unveil the meaning behind every phrase. NMT functions as an programmed neural network, making translating complex sentences and entire documents a breeze.

While exact speed comparisons are hard to come by since the variety of languages, complexity, and length can be so far-ranging, AI translation tools can understandably work much faster than human translators. This makes AI translations a go-to solution for handling high-volume content translation—especially for multiple languages at once—when time and efficiency are critical. 

AI also gets more refined and accurate over time, and therefore lightens the load on human editors by providing a better translation to start.

3. Cost savings from automating Translation with AI

On average, human translation costs from $0.15 to $0.30 per word. Certain industries like retail or gaming can be cheaper, but translating more specialized medical or legal documents can cost upwards of $1.00 or more per word (Unbabel). 

Some of the most popular machine translation engines like Google Cloud, Amazon, and Microsoft offer translation for as low as $0.000010 per character. 

If you needed to translate a typical blog post—about 2,000 words or ~12,906 characters—you’d get an instant, very passable translation for $0.12 from a machine translator, and $300 from a human one. 

Those are massive cost savings for any business. Plus, most machine translation tools now have post-editing options for a smidgeon more—where human editors review translations for accuracy, tone, and voice.

Why AI Translation still needs human help

While AI can churn out translations at lightning speed, it can sometimes trip over cultural nuances or miss the mark on context-specific interpretations or highly specialized content (like medical or legal documents). Not only that, but certain language pairs tend to be more accurate (usually English = other European languages) than others that have less demand and input data (NMT can struggle with Arabic and Chinese languages in particular). 

This is where the dynamic duo of technology and human oversight becomes indispensable—and why, for some use cases (like moving to a market with less practice data for AI), you just can’t beat a human translator. Or at the very least, an editor who breathes. 

People play a crucial role in fine-tuning and perfecting AI's output, ensuring that the translation isn't just accurate, but resonates on a human level. (And thankfully, as we’ve quelled similar fears in other industries, the need for experienced translators is only growing.)

Why and when to use AI Translation

AI has completely transformed the way companies interact with their audience (and vice versa). Customers expect highly personalized user journeys, and therefore, communicating with customers in their first language has become table stakes. 

Here are some reasons why companies are increasingly turning to AI translation tools:

To translate large amounts of content in a short time

To translate repetitive content   AI translations offer a more efficient and budget-friendly alternative to hiring professional human translators. These tools can process large volumes of text in seconds, allowing businesses to save both time and money on translation tasks without sacrificing quality.

To translate in real-time

With the ability to translate text and speech in real-time, AI translation tools enable companies to communicate effectively with people from diverse backgrounds. This creates better relationships, improves customer satisfaction, and expands the company's reach in global markets (win-win-win). 

To scale your global projects or operations

As a company expands its operations and deals with more languages, AI translation tools can effortlessly scale to meet these growing needs. This scalability ensures businesses can continue to provide timely and accurate translations regardless of the size or complexity of their projects. A perfect use-case for live, global translation projects is chatbots, or training materials for new markets.
