Challenges of Automated Subtitling

While machine translation has been used in localization for a long time, a few new challenges are present in subtitling projects:


For both humans and machines alike, not knowing when one sentence ends and the next sentence starts provides a challenge. Most subtitles lack end-of-sentence markers, and most have sentences that are split between frames; these issues need to be fixed before translation.

    Stylistic requirements would normally be specified in a style guide for human translators, but they can also be applied through rules and machine learning for an automated process. As an example, profanity may be quite acceptable in the US market, but the vocabulary must be toned down considerably for a Thai-speaking audience by instructing the MT engine to soften any profanity found.

      Translation can result in shorter or longer text strings compared to the source language. Timing cues need to be adjusted in each frame, and sometimes frames must be inserted or deleted to accommodate these length changes.

        As the input to MT is complete sentences, the output from MT is also complete sentences. It must be reformatted into a subtitle format such as SRT or TTML.

          Solutions for Automated Subtitling

          In addition to the actual translation, there are several processes surrounding the creation and localization of subtitles that typically require significant human efforts. Many of these processes can be automated by Media Studio:

          Before a subtitle can be translated, a source language subtitle is usually made available. The layout and structure for each screenplay is wildly different, and even a human can take considerable time to extract dialog from the surrounding noise of video directives, mood indicators, general time stamps and other supporting information. Fortunately, these tasks can be automated – saving time and cost, and minimizing human error.

            The second means of creating subtitles is using the audio-visual content as a source. This can be used with or without the dialog and metadata from the screenplay but is more accurate when the screenplay data is available. The accuracy of speech recognition, especially in videos where there is music, loud background noise or other factors, is not perfect, but accuracy has improved in recent years.

              The final challenge is the addition of timing information. Timing relates to when the actual text is spoken in a movie, as well as the timing of the frame changes. The time of the frame changes is important to understand; subtitles can be split across different frames, and if necessary can be adjusted and paraphrased to match the desired reading speed. Timing is adjusted by analyzing the audio-visual content, considering when people start and stop speaking as well as what scene changes and other country- and language-specific variables may be relevant.

              Typically, creating original source-language subtitles for a 90-minute video as an SRT or TTML file with the correct timing cues can take between 36 and 48 hours. By combining the above approaches, the time needed can be reduced from days down to a few hours.
