Soustitrage

Soustitrage refers to the process of adding subtitles to a video in a different language or in the same language as the audio. Subtitles are text displays that appear on the screen to convey dialogue, narration, or other audio information. The primary purpose of soustitrage is to make video content accessible to a wider audience, including those who are deaf or hard of hearing, or those who do not understand the original language of the audio.

There are several types of soustitrage. Open subtitles are permanently embedded into the video and cannot be turned off. Closed subtitles, on the other hand, are a separate track that can be toggled on or off by the viewer. This is often achieved through video file formats that support multiple audio and subtitle tracks.

The process of creating subtitles involves transcription of the audio, translation into the target language, and timing the text to synchronize with the on-screen action and dialogue. This can be done manually by professional translators and subtitlers, or with the assistance of automated speech recognition (ASR) technology, which can then be refined by human editors.

Soustitrage plays a crucial role in global media distribution, allowing films, television shows, and online videos to reach international audiences. It also enhances accessibility for individuals with hearing impairments, providing a vital alternative or supplement to spoken audio.
