Part 1. How AI Subtitle Translators Work

Before we move on to the best subtitle translators, it’s important to understand how these AI tools work.

How Automatic Subtitles in Multiple Languages Work

Auto-translated machine or AI captions, or multilingual subtitles, offer real-time subtitles in a different language alongside the source speech. They are created through automatic speech recognition, machine translation technologies, or AI-based solutions. These tools convert audio into text (or speech) in the target language.

How To Measure Translation Quality

When you let AI translate subtitles, there can be quality issues. The Multidimensional Quality Metrics (MQM) framework, led by the European Commission, categorizes translation quality issues, including accuracy, style, fluency, locale conventions, terminology, etc. Organizations often provide translators with style guides glossaries, and build a translation memory for consistency across their works. The quality of translation is assessed based on usefulness and how well it serves its purpose.

Machine Translation for Live Captions – Not All Are Equa

In the last two decades, Language Service Providers (LSPs), translation agencies, and freelancers have adopted machine translation to enhance productivity and reduce costs. Various text-to-text translation engines exist, such as Google Translate, DeepL Translate, and Microsoft Translator, utilizing different types of machine translation like rule-based, statistical, adaptive, and neural. Neural machine translation has gained popularity for its powerful and satisfactory results, although different engines may excel in specific language combinations and produce varying results.
