How to Brief a Korean Voice Casting Studio (What Clients Almost Always Get Wrong)

When a campaign sounds off, most clients assume the problem is the voice actor. In reality, the problem usually arrived long before anyone stepped into the booth - it arrived in the brief.
A well-structured brief is the single most important document in any voice casting project. It tells the studio who you're trying to reach, what the content needs to feel like, and how the final audio will be used. When that document is vague, incomplete, or built on assumptions that don't translate across cultures, no amount of talent or technical precision can fully compensate.
This is especially true when working with a Korean voice casting studio. The Korean voice acting industry operates with its own professional conventions, linguistic structures, and cultural expectations - and international clients, even experienced ones, frequently approach it using frameworks built for English-language production. The result is delays, reshoots, and a final product that functions but doesn't quite land.
Here is what clients consistently get wrong when briefing a Korean voice casting studio - and exactly what to do instead.
1. Describing Tone Without Cultural Context
The most common mistake in any international brief is using tone descriptors that haven't been localized.
Words like "warm," "friendly," "authoritative," or "conversational" carry very different performance implications depending on the cultural and linguistic context. In Korean commercial voice work, what reads as warm and approachable for a North American audience may register as overly casual or even unprofessional for a Korean one. Conversely, a delivery that sounds appropriately formal in Korean can feel cold or detached to a Western ear when played back.
This is not a matter of translation - it is a matter of cultural calibration. Korean audiences are highly attuned to vocal register, and the perceived credibility or warmth of a voice performance is shaped by factors that do not map cleanly onto English-language descriptors.
Rather than providing tone adjectives in isolation, anchor them with reference material:
A link to an existing Korean-language campaign you respond to positively, even if it is from a different brand or category
A description of your target demographic in the Korean market - age range, socioeconomic context, and the platform or medium through which they will encounter the content
Whether the content is being localized specifically for Korean audiences, or produced in Korean as part of a multilingual international release
These distinctions directly affect casting decisions, vocal register, pacing, and performance direction. A thirty-second commercial targeting Korean women in their forties on broadcast television requires a fundamentally different approach than a product explainer video targeting Korean-speaking users of a global app.
2. Submitting a Machine-Translated Script
This happens more often than studios would like to admit, and it creates cascading problems throughout production.
A machine-translated Korean script is rarely performable as written. Korean sentence structure places verbs at the end of the clause, which means pacing and breath points fall in entirely different places than in the source language. Honorific levels - the formal register system built into Korean grammar - must be selected based on the relationship between the speaker and the listener, and cannot simply be defaulted to a neutral form without affecting how the content is received.
Beyond grammar, certain English marketing constructions have no clean Korean equivalent. Calls to action, taglines, and idioms that work perfectly in English often sound clumsy, awkward, or even unintentionally comedic when rendered literally in Korean. A phrase like "just do it" is globally understood because of decades of brand investment - but a new brand attempting an equivalent construction in Korean will not have that context working in its favor.
If you are submitting a translated script, have it reviewed by a native Korean speaker with localization experience before briefing the studio. Better still, brief the studio first and allow them to flag translation issues before recording begins. The cost of a script revision is always lower than the cost of a re-record - and significantly lower than the cost of launching content that native speakers find awkward.
3. Leaving Out Technical Specifications
Voice casting briefs are not just creative documents - they are production documents. Missing technical details create delays, miscommunications, and in some cases, entirely unusable audio.
A complete technical brief should include:
Delivery format: Specify the required file format (WAV, MP3, AIFF), bit depth (typically 24-bit for professional production), and sample rate (44.1kHz or 48kHz depending on intended use). Broadcast, streaming, gaming, and telephony each have different technical standards, and the studio needs to know which applies before recording begins.
Lip-sync requirements: If the audio must match existing on-screen mouth movement - in a dubbed video, a game cinematic, or an animated spot - this must be flagged explicitly in the brief. Timing-locked recording requires a fundamentally different workflow, often involving frame-accurate cue sheets and multiple directed takes per line. A free-read narration project and a lip-sync dub are not the same job.
Usage rights: Broadcast, digital, in-game, corporate internal, e-learning - each usage type carries different contractual implications for voice talent. Rights are not assumed; they are negotiated. If you do not specify intended usage in your brief, you may find that the original agreement does not cover the platform on which you ultimately publish.
Deadline and revision structure: How many rounds of directed takes are included in scope? Is there a remote session option via Source-Connect or a similar platform? What is the turnaround expectation for deliverables after the session? Ambiguity here leads to scope disputes.
Character and timing constraints: For gaming and e-learning projects in particular, audio often needs to fit within fixed UI containers - a line cannot run longer than a set number of seconds, or must fit a specific character limit when displayed as subtitles. These constraints must be provided upfront, not flagged after delivery.
4. Confusing Dubbing Briefs with Localization Briefs
These are related but distinct workflows, and briefing one as though it were the other produces predictable problems.
Dubbing is the process of replacing the audio track of existing recorded content. It requires timing synchronization with the original performance - matching not just meaning, but lip movement, emotional beats, and scene pacing. A dubbing brief must include the original video file, a time-coded script, and clear direction on how closely the Korean performance should mirror the source.
Localization is broader. It involves adapting content - which may include script, tone, cultural references, and brand language - so that it resonates authentically with a Korean audience, rather than simply existing in the Korean language. Localized content does not always mirror the source directly; sometimes the most effective localization involves rewriting a line entirely to preserve intent rather than form.
International clients frequently submit a localization request with a dubbing-style brief - or vice versa. Being clear about which workflow you need, and why, allows the studio to staff and schedule the project correctly from the start.
5. Treating Casting as an Afterthought
International clients frequently send a fully approved script, a locked deadline, and a request to "cast someone suitable" - with two business days between them.
Casting is not a same-day task. Finding the right voice for your brand or character involves reviewing talent pools, shortlisting based on the specific emotional register your project requires, running auditions, evaluating takes, and sometimes directing multiple rounds before a selection is confirmed. For multilingual projects involving more than one language pair, this process multiplies accordingly.
Build casting time into your production schedule from the outset. A practical guideline for standard projects:
Commercial or corporate narration: Allow a minimum of five to seven business days for casting
Multi-character game or animation work: Allow two to three weeks, particularly if characters require distinct vocal personalities or regional accent considerations
Multilingual projects (two or more languages): Add a minimum of one week per additional language, accounting for independent casting in each market
Rushing casting does not save time in the overall schedule - it transfers the risk downstream, where fixing a miscast performance is far more expensive than selecting the right one at the start.
6. Not Identifying the Decision-Maker
Recording sessions - whether remote or in-studio - require real-time creative decisions. Who approves a take? Who can authorize a change to the script mid-session? Who has final say on performance direction if the director and the client disagree?
When that chain of authority is unclear, sessions stall. The voice actor waits. The engineer waits. The director waits. And the client - who is available but was not identified as the approver - escalates the issue after the session ends.
Before your project enters production, designate a single point of contact with the authority to approve or redirect in real time. Brief that person on the project's core creative objectives - not just the script - so they can make informed calls without needing to escalate every decision. If your approver is not available for the duration of the session, schedule around their availability rather than proceeding without them.
7. Providing No Brand Voice Reference Whatsoever
This is particularly common with first-time clients and with brands entering the Korean market for the first time. The brief arrives with a script, a deadline, and a note that reads something like: "We'll know it when we hear it."
That is not a brief. That is a casting call with no criteria.
A brand voice reference does not need to be Korean-language content. It can be:
Two or three existing ads or videos from your brand in any language, demonstrating the vocal personality you have established
A list of brands whose voice you find aspirational, and a brief note on what specifically you respond to
A mood board or tone document, even if written rather than audio - describing the qualities you want the voice to project and, equally usefully, what you want to avoid
The more context a studio has about where your brand sits on the spectrum from authoritative to approachable, from energetic to measured, from premium to populist, the better positioned they are to cast the voice that will serve it.
A Brief Checklist Before You Hit Send
Before submitting your brief to a Korean voice casting studio, confirm that it includes the following:
Project overview: What is the content, where will it be used, and who is the intended audience in the Korean market?
Script status: Has the script been reviewed by a native Korean localization professional?
Tone reference: Have you included audio or video references, not just descriptive adjectives?
Technical specs: Format, bit depth, sample rate, lip-sync requirements, and usage rights
Casting timeline: Have you allowed adequate time for auditions and selection before the recording date?
Session approver: Is there a designated decision-maker available for the full duration of the session?
Revision scope: How many rounds of revisions are included, and what is the approval process?
Deadline: What is the final delivery date, working backwards from your launch or submission date?
A brief that answers all of the above does not guarantee a perfect outcome - but it gives every person on the production team what they need to do their job well. And in voice production, that is usually enough.
