Glossary Terms

A

ADR- “Automated Dialogue Replacement” or “Additional Dialog Recording”. The process of re-recording dialogue by the original actor (or a replacement actor) after the filming process to improve audio quality or make changes to the originally scripted dialog. Sometimes also referred to as “Additional Dialog Recording.”

Adapter/Adaptation – Once a script is translated, it must be adapted to take into account synchronization and cultural adaptation so the audience is given the impression that the actor is speaking in their language. A global audience deserves to experience dubbed content in a way that authentically represents their culture, traditions, values, and native language.

Algorithm – A procedure or formula for solving a mathematical problem, generally based on a series of specific instructions.

Artificial intelligence – refers to developing computer systems capable of performing tasks that usually require human intelligence.

Assignment of rights – A contract between a performer and a content producer (usually with the LSP as an intermediary) that assigns the usage rights for the performer’s work on a given project. (e.g., the actor’s performance can be used for Theatrical, Home Entertainment, Marketing, Social media, Streaming, etc.) for the “Fee being paid for the performance. Often, a point of negotiation between the actor and the producer/distributor as to the scope and duration of the ” Assignment of Rights.”

Audio description – A narration track to be played with a program to describe and provide information on visual elements for the visually impaired.

Audio layback – In the domain of audio/video production layback is the process of laying audio back in to video for the final video product. During video projects it is common for the audio and video to be edited separately (sometimes in separate facilities in different states or countries).

Audio lip sync – The process of achieving lip sync through manipulation of the audio track, whether by means of AI or manual editing.

Audio mixing – Process of combining and adjusting different audio elements, including dialogue, music, and sound effects; balancing levels to obtain a natural and clear sounding mix to meet the desired quality and cultural standards. Audio elements may also be positioned spatially to create a more immersive experience. When mixing the localised voiced with the M&E, the audio engineer applies for example the proper voice treatments and panning and perspectives to the dialogues matching the original version.

B

Back Translation – Also called reverse translation, is the process of re-translating content from the target language back to its source language in literal terms.

C

Casting – A dubbing director will choose voice actors to play the roles in a production (movie or television). This voice actor will likely have a similar sound and tone as the original actor and be a native speaker of the dubbed language. The cast actor will have a similar tone, texture, age, and weight to the original.

Cast list – Complete list of all actors (voice or live action) that perform in a program.

Creative letter / dubbing guide – This is the bible of the project for localization purposes. It describes the dubbing strategy. Includes a synopsis of the story, description of the main characters, their voice types and some information of the original actors, translation and adaptation notes describing important cultural matters and slang, vocals and ditties information, foreign language notes, casting list and word count and also provides legal information and M&E notes.

Conform- The process of synchronizing video, audio, and/or timed text.

DME stems – “Dialogue, Music, and Sound Effects”: Audio stems that contain all these elements separated. Allows to make adjustments to specific audio elements without affection the entire mix.

E

Efforts – Missing additional sounds that have to be worked into an audio mix (“efforts”, various production sounds that end up on the dialg track, etc.)

Established voice – Local territory actor who has consistently recorded dubbed audio for specific original version actor(s).

F

Foley – Sound effects created that mirror on-screen action. in the context of Localization, it can be recorded to replace, or record sounds that are culturally specific, but more often when the quality of the original audio elements in the source content does not meet the desired standards for the localized version.

Forced narrative – A timed text file that translates on-screen text, or foreign dialogue different from the original language, that is plot pertinent and allows the audience to understand a scene. On-screen text may include signs, plaques, or any type of wording shown in a scene.

Full mix – Final Audio Mix that combines all necessary audio elements, including dialogue, music, sound effects, and any other required audio components; balanced and adjusted to achieve the desired sound quality and overall audio experience required in formats such as stereo and surround sound.

G

Generative AI – A branch in the field of artificial intelligence that focuses on creating new and original content based on pre-trained data models.

H

Home studio – A voice actor may have designed and built a studio in their home to allow them to record remotely. These home studios typically meet similar requirements that a normal studio would have, most importantly, having no external noise that could be picked up in the recording. Pre-fabricated home studios called “whisper booths” are commonly used.

I

Insert list – Documentation of on-screen text that will require translation to the target language for graphic or forced narrative inclusion.

L

Labials – Labials are lip movements involved in forming speech. The most noticeable artifact is lips touching during the vocalization of a dialogue, such as occurs with the consonants M, B, F, P, and V. The term “Labials” included also includes visual expressions of speech involving teeth (dentolabial) and tongue.

Lectoring (Lektoring) – A dubbing style mainly used in Poland. Utilizing only one actor who speaks all the lines of every actor in the program, reading all the translated dialogue.

Line – A sentence part of the dialogue of a character.

Lip sync – Matching dialogue to mouth movement of character speaking. This has to match the amount of syllables in the dialogue and the labials.

Lip sync adaptation – The process of achieving lip sync through changing the text of the dialogue.
