What is machine translation?

Machine translation is a process where a computer reads text written in one language and then converts it into another language. It's a form of automatic translation.

Where is machine translation used?

Machine translation can be used on any digital platform and in any digital format. From websites to mobile devices, applications, videos, audio, images, and texts.

Why do we need machine translation?

Machine translation is used to convert texts from one language to another so that people who speak different languages can understand what is written. Beyond the need for translation which could be met by human translators, machine translation software makes the process:

  1. Faster. A human translator will take 5 days to translate 10,000 words. On the other hand, machine translation can translate 100,000 words in seconds.
  2. Cheaper. The cost of translating 400,000 words which usually requires editing is an average of $40,000. With machine translation software, this can be done for $30.

What are the types of machine translation tools?

The types of machine translation tools could also be referred to as the levels of development machine translation technology has passed through. They are:

  1. Statistical Machine Translation (SMT) which translates words verbatim.
  2. Rule-Based Machine Translation (RBMT) translates by comparing grammatical rules.
  3. Hybrid Machine Translation (HMT) is a combination of statistical machine translation and rule-based machine translation. 
  4. Neural Machine Translation (NMT) uses artificial intelligence to learn languages as a human would, and carry out translations. NMT is a constantly improving translation system.

These are the four main types of machine translation tools. Choosing any one type of machine translation tool is not a topic for consideration. Each is an improvement on the former.

What are the three types of translator software?

The three types of translator software are compilers, interpreters, and assemblers.  They control how translation software interprets an instruction before processing it. You can think of them as “the software behind translator software.” 

They each represent ways a computer may interpret the language you want to translate (source code) into something readable; an object code (also known as machine code).

  1. Compilers translate source codes word for word; requiring a lot of storage space.
  2. Interpreters translate source codes sentence by sentence; taking a long time to process.
  3. Assemblers assemble the entire source code like mnemonics for complete translation.

Fortunately, you don't need to know all this information to use machine translation software.

What is the difference between a compiler and a translator?

A compiler is one way a computer receives the source code of a language before it processes it for translation. A translator on the other hand is a computer that translates source codes from one language to another.

How accurate is machine translation?

The accuracy of machine translation is not something that can be put to a clear test. Accuracy varies depending on the language pair being translated. For example, the language pairs of countries in the EU region enjoy accurate translations due to their large volume of translated copies of literature within the region. Overall, machine translation is 60%-80% accurate.

Pro tips for using machine translation software 

  1. Hire a professional translator.

Machine translation software does not currently provide accurate and contextualized translations. A professional translator will help you edit and make corrections to the translation work. Machine translation software helps you save time. Professional translators ensure your work fits and passes the right message in the target language.

  1. Hire a translator with experience in your domain.

Don't hire anyone who can speak and write your target language fluently. Make sure they are experts in the industry or domain you need the documents translated.

  1. Use Computer Automated Translation (CAT) software for all your editing.

A CAT software stores the trails of the edited work in its Translation Memory (TM). Using a CAT eliminates the need for recurring edits. These edits get saved up in the TM for auto-recall the next time you need to make a similar correction.

  1. Compile and use a glossary.

Have a glossary of brand-specific terminologies you don't want tampered with in the machine translation process. Uploading this glossary to your machine translation software will reduce translation errors and editing periods over time. 49% of translation errors are due to incorrect terminology. Keep, update and use your brand glossary.

  1. Insist on a proper onboarding process.

Do not kickstart the translation phase of your business without first ensuring your team is proficient in using the machine translation system you have chosen. A thorough onboarding process will give your team a solid understanding of how the key features and data security system function. An onboarding process will ensure workflow agility, security, and reduced costs. 

A great machine translation system offers training as part of their onboarding process. Don't hesitate to reach out to support when you face challenges.
