What is Machine Translation? Unlocking the Power of Language

In an increasingly interconnected world, the ability to communicate across language barriers is more important than ever. This is where machine translation (MT) comes into play, a fascinating and rapidly evolving field at the intersection of linguistics, computer science, and artificial intelligence. But what exactly is machine translation? At its core, it’s the use of software to translate text or speech from one language to another. 

In this article, we will delve into the world of machine translation, exploring its history, how it works, and the various technologies that drive it. We’ll also examine the challenges it faces, its limitations and the potential it holds for the future. Whether you’re a language enthusiast, a tech aficionado, or just someone curious about how technology is breaking down language barriers, this article aims to provide a comprehensive overview of the fascinating world of machine translation.

What is Machine Translation?

Machine translation is a remarkable process that uses software to convert text or speech automatically from one language to another. Its goal is to achieve what was once only seen in science fiction: a seamless and automatic way for people of different languages to communicate with each other.

Before computers came into existence, the only way to understand content in another language was to learn both languages or rely on a bilingual speaker for translation. In the 1950s, Warren Weaver and other pioneers conducted early research into machine translation. However, the rule-based approach of the machine translation engine developed at that time had limited application. Over the years, remarkable advancements have been achieved in software-based language translation. Thanks to the power of machine learning and AI, translators have witnessed significant enhancements in both quality and accuracy, enabling seamless and near real-time conversions.

Today, machine translation finds extensive applications across various contexts. It empowers tourists to effortlessly visit and communicate with locals who speak different languages. Moreover, content creators, influencers, and companies can leverage the power of machine translation to effectively reach and engage a diverse and extensive audience.

Types of Machine Language Translation

Rule-Based Machine Translations (RBMT)

This approach involves a set of linguistic, grammatical, and lexical rules to translate text from one language to another. It’s a similar process if you were to use a language dictionary and translate every word or phrase yourself.

The accuracy and success of a rule-based machine translation rely on getting experts and native speakers to create these explicit rules. Creating a comprehensive “dictionary” of these rules that covers every aspect of the language takes time and effort, which makes RBMT especially difficult to scale.

Furthermore, RBMT’s rule approach can make it too rigid, which is problematic because most languages are fluid and dynamic. For example, an RBMT might have trouble understanding recent additions like slang, idioms, and expressions.

Nevertheless, a rule-based approach has been successfully used for decades in certain domains and language pairs. It’s best for situations where a quick understanding is prioritized over accuracy or when words are simple enough. Street signs with simple commands are a good example.

Statistical Machine Translations (SMT)

SMT is an approach that relies on statistical models rather than on linguistic or syntax rules.

This model is fed a large volume of texts in two or more languages that are translations of each other, helping identify correspondences of words and phrases between these languages.

When it comes to translation, SMT software evaluates potential translations using training data and selects the most probable words and phrases. This process ensures that the resulting translations are fluent and grammatically accurate.

Compared to RBMT, SMT is notably more precise and adaptable. By updating its training data, you can facilitate its quick adaptation to new expressions and even employ domain-specific training for more effective translation of technical documents.

However, SMT still shares some limitations with RBMT, such as challenges with idioms, complex sentence structures, and ambiguous translations. Consequently, SMT proves particularly valuable for domain-specific applications, such as those in the fields of science or law.

Neural Machine Translations (NMT)

Neural machine translation (NMT) is an approach that leverages artificial intelligence to translate. Machine learning gives NMT unparalleled flexibility and adaptability, thanks to the ability to learn and improve its translations over time.

Because of this, NMT is currently the leading technology in machine translation, NLP, and other text technologies. It delivers exceptionally more accurate results than RBMT and SMT, even with complex sentences and expressions. Best of all, it can produce output capturing nuances, making it seem human-like.

Some disadvantages remain, however. The success of a neural machine translation platform hinges on its training data. If it’s bad, the translations won’t be as accurate. Also, NMT is computationally intensive, requiring extensive hardware and resources that can be expensive to maintain.

Despite its limitations, NMT remains the best machine translator and shows promise for further improvement as researchers actively address its challenges.

Hybrid Machine Translations (HMT)

A hybrid machine translation (HMT) software combines two or more of the other translation methodologies described above. The goal is to leverage the strengths of each while overcoming their weaknesses.

For example, a hybrid system might use a neural network for its primary translation, only using a rule-based approach for certain domains or language nuances. Alternatively, a primarily rule-based system can use AI to adapt and change these rules automatically.

Because HMT uses multiple approaches, the accuracy can be greatly improved. Furthermore, limitations and special cases can be tackled easily.

The main problem is that hybrid machine translators can be more complex to develop and maintain. Integrating, maintaining, and fine-tuning multiple systems can be a programming nightmare.

Also, if the HMT system uses AI, it would be even more resource-intensive than an NMT approach.

Benefits of Machine Translation Software

Fast

Machine translation enables businesses and professionals to translate large volumes of text quickly and accurately.

For instance, using Sonix, it takes just a few minutes to transcribe and translate the text of an hour-long video. Compare that to a human translator, who not only needs to watch and transcribe a video manually but also evaluate each sentence in real-time. In other words, an hour-long video will take them an hour or more to translate.

Moreover, machine translation enables seamless text conversion from one language to another in nearly real-time, facilitating effective communication. This capability proves invaluable in specific scenarios, such as when travelers venture into foreign countries. 

Applications like Google Translate empower individuals to effortlessly decipher street signs and comprehend conversations with locals, thereby enhancing their overall experience in unfamiliar territories.

Affordable

Utilizing machine translation tools to convert text across languages is a much more cost-effective alternative than hiring human translators. To put things into perspective, professional translators may charge up to 30 cents per word. Consider a standard 1,000-word document, already amounting to a hefty $300. If you multiply that by the number of documents you typically handle in a month, you’ll quickly realize how the expenses stack up.

Compare that to machine translation software, which is significantly cheaper and can produce equally impressive results. For example, Sonix only charges $10 per hour of video to be transcribed and translated. 

The low cost and fast speed of machine translation software make them easy to integrate into your existing workflow.

Accurate

Gone are the days when machine translations yielded such inaccurate results that human editing was necessary to achieve anything remotely acceptable. As mentioned earlier, machine translations have transitioned from rule-based approaches to more precise AI-based methods. When combined with technologies like natural language processing (NLP), the output is comparable to that of a human.

Moreover, AI offers an additional advantage—adaptability. Machine learning algorithms can refine their datasets with each translation encounter, potentially leading to even greater accuracy in the future.

Multitude of Language Options

Machine translation gives you instant access to various languages, enabling you to convert your content easily into any or all of them.

In the past, if you needed to translate text into multiple languages, you’d need to hire a human translator for each. Apart from high costs, this is a time-consuming process. Furthermore, there could be variations in the translations depending on the skill of the translator, which could lead to inconsistencies.

But with machine translation software, this issue is a thing of the past.
