Professional and experienced translators in audio translation

Adelphi’s Audio Translation Services ensures that all our translators are professional and work only into their mother tongue and have experience of audio translation. This ensures accuracy.  All our translators are members of either the Institute of Linguists or the Institute of Translations & Interpreters. They will also have a minimum of three years of experience in professional translation. Your project is matched to the most suitable translator with the relevant expertise to translate your document.

Voice-over translations

Voice-over translations are a more specialist area when compared to standard translations. Voice-over translations must be restricted to fit the same time-slot as the original otherwise the voice-artist may have to speak faster to make it fit. If the voice-over is going to be used over a video of a different language, then the voice-over translation may include time-codes to help the voice-artist and engineer sync up the voice to the video.

The style of translation is important for voice-overs and should reflect the genre, e.g. if it is for marketing, public information, drama etc. The audio translator will have a copy of the video as a reference and is instructed to translate using a style to match the source material. All our translators have signed an NDA (none disclosure agreement).

This project was recorded in French, Danish, Dutch, English UK, Finnish, Japanese, German, Greek, Italian, Norwegian, Polish, Portuguese, Spanish, Swedish, Turkish, Russian, Chinese, and Korean.

Subtitle translations (SRT)

Adelphi produces SRT files in any language, including making transcriptions of the source video before they are translated to create SRT files for subtitling. Some clients want only the SRT file so that they can produce their own subtitles while others want us to provide the finished video for them.

In SRT subtitling translation, our audiovisual translator (SRT file translator) would create translated subtitles in the target language directly from the source video. Our subtitle translator would then create SRT files that are used to produce burnt-on subtitles.
