How Surtitles and Open Captions Work in International Theatre

In an international production, part of the audience may be reading while listening, watching movement, or relying on text to follow dialogue they cannot hear. Surtitles and open captions are the two most visible text systems used to bridge that gap. They are related, often confused, and not interchangeable. The short answer is that surtitles are usually timed translations displayed above or beside the stage, while open captions are always-visible access text for Deaf, deafened and hard of hearing audiences. Many theatres use the words loosely, so the first practical question is not ‘What is this called?’ but ‘What is this text for?’

Definitions: surtitles, captions and subtitles

A Routledge chapter on surtitling and captioning defines surtitling and captioning for theatre and opera and examines their history and practice. It notes that surtitling originated as a service in opera, where surtitles provide the translation needed to understand text written in another language, and it discusses formal experimentation driven by technical change.

Open captions are a presentation mode as much as a text type. The text is displayed continuously for everyone in the auditorium, rather than being switchable by an individual viewer as closed captions are. In live theatre, captioning is therefore usually ‘open’: the audience sees the same screen or projection. The screen may be at the side of the stage, above it, or on a seat-back display, depending on the venue and production.

Stagetext, a deaf-led charity, separates three practices that are often lumped together. Theatre captioning is for scripted performance and is prepared and cued live by a theatre captioner. Live subtitling is for unscripted speech and is produced live by a speech-to-text reporter. Digital subtitling is for pre-recorded video and is prepared by a digital subtitler. The distinction is useful because each has a different workflow, risk profile and skill set.

Terminology varies by country and company. Some producers call translated surtitles ‘captions’ when they are displayed on screens. Others keep ‘surtitle’ for translation and ‘caption’ for access. No single usage governs the field, so contracts, programmes and technical riders should define the actual deliverable rather than rely on the label alone.

Translation and access are different briefs

Surtitles primarily answer a translation question: what does this text mean for this audience? They may translate from one language to another, or make an unfamiliar register, dialect or sung text easier to follow in the same language. The Routledge chapter notes that interlingual surtitles can serve three broad audiences identified by Yvonne Griesel: source-language audiences, target-language audiences, and audiences with knowledge of both source and target languages. That is a useful corrective to the assumption that there is one monolingual spectator.

Open captions primarily answer an access question: what is being said, who is speaking, and what else is happening that a Deaf or hard of hearing audience member needs in order to follow the performance? Stagetext describes captions and subtitles as the verbatim, accessible text that allows deaf, deafened and hard of hearing people to experience live theatre, musicals, museums, tours and author events. Captions may include speaker changes and sound information, and they can be used for same-language performance as well as translated performance.

Because the briefs differ, one text cannot simply be reused for the other without adaptation. A translation may condense repetition, explain a cultural reference briefly, or leave a joke to the performance. An access caption track may need to mark overlapping speech, offstage voices, music or significant sound effects. If a production wants a single display to do both jobs, the creative team has to decide which information is essential, who is the primary audience, and how any loss will be explained or mitigated.

How surtitles are made and cued

Surtitling is a production process, not just a translation pasted onto a screen. Although methods vary, a typical workflow has five stages.

1. Text preparation. A translator or dramaturg works from the script, libretto or production text, often alongside the director and creative team. The translator decides what to translate, what to leave in the source language, how to handle songs, jokes and cultural references, and how closely to follow the original syntax.
2. Segmentation and condensation. The text is broken into readable units that can be displayed at performance speed. Long speeches may be condensed; overlapping dialogue and ensemble numbers may need special solutions. The aim is not a literary transcript but a readable trace of the performance.
3. Display planning. The team chooses screen positions, font size, contrast and line length, then tests them from different seats. A surtitle that is legible from the centre of the stalls may be invisible from the side or from the balcony.
4. Cueing. An operator follows the script, score or stage action and triggers each title live. Cues may be marked in a special cue script and rehearsed with the production. In opera, the operator may follow the score; in spoken theatre, cues may follow stage business or an actor’s line.
5. Documentation and revision. The final cue script, translation and operator notes are kept for revivals, tours and different venues. Previews are used to adjust timing and line breaks before press performances.

Surtitles can be projected above the stage, shown on side screens, or delivered on individual displays. The choice affects audience attention and the performers’ relationship with the text. A screen that demands constant eye movement may pull focus from the stage; a screen that is too small or too high may exclude part of the house. Technical experimentation is part of the field, as the Routledge chapter notes, but it should be tested with real sightlines rather than assumed.

How open captions work in theatre

In scripted theatre, the captioner usually works from a prepared script and cues the text live, in the model described by Stagetext. The captioner may sit in the auditorium or a technical position, following the performance and displaying text on an LED screen, projection or caption unit. The audience sees the text as part of the performance, not as an optional layer.

Open captions can serve several production formats:

• Scripted performance. Prepared theatre captioning, cued live by a captioner, is a common model for plays and musicals. It can include dialogue, speaker labels and descriptions of significant sound.
• Unscripted speech. Live subtitling by a speech-to-text reporter is used for talks, panels, improvisation and post-show discussions, where advance preparation is limited.
• Recorded and streamed work. Digital subtitling is prepared for pre-recorded video, including recorded theatre, trailers and online archives.

Access captioning is not a niche concern. AMT Lab cites the National Institute on Deafness and Other Communication Disorders estimate that one in eight people in the United States aged 12 and over have hearing loss in both ears, and argues that performing arts organisations have an interest in making work accessible. The same logic applies internationally, even where the precise statistics and service models differ.

Designing text for international audiences

An international production may need translation surtitles, access captions, or both. The decision should be made early, because it affects budgeting, rights, casting, rehearsal, screen design and front-of-house communication. A festival with several language communities may need a language policy, not just a single screen.

Audience language mix. If the production is in Language A and the audience is largely Language B, surtitles in B are the obvious baseline. But international festivals also attract source-language speakers, bilingual spectators, and Deaf audience members who may use a different language or modality. Griesel’s three-audience model is a reminder that the same title track can be read for different purposes.

Sightlines and attention. Test every screen from the back row, the side slips and the accessible seating positions. Check whether the text overlaps with surtitle-unfriendly moments, such as fast movement, darkness or a busy set. Consider whether the audience can read the text and watch the stage without losing the performance.

Reading speed and density. Surtitles and captions are read in real time. Long lines, rapid changes and dense cultural explanation increase cognitive load. Translators and captioners need time to edit, and operators need rehearsal to match the text to the performance rather than to a stopwatch alone.

Access beyond text. Text is only one part of accessibility. Venues publish information about step-free access, lifts, service dogs, personal assistants and other provisions; Internationaal Theater Amsterdam, for example, sets out general and reduced-mobility provisions on its accessibility page. Producers should coordinate captioning with front-of-house staff, ticketing and pre-show information.

Rights and permissions. Translating a play or libretto and displaying that translation usually engages rights in the underlying work. Requirements vary by work, licensor and territory, so producers should clear translation, surtitle and recording uses with the rights holder and confirm what is permitted before rehearsals.

Ethics of representation. Translation and captioning are interpretative acts. Word choices can soften or sharpen a play’s politics; sound descriptions can direct attention. Where possible, involve the translator, dramaturg, captioner and Deaf or hard of hearing advisers in decisions that affect meaning and access.

Common misconceptions and a practical checklist

Several assumptions cause avoidable problems. Surtitles are not simply subtitles moved above the stage; they have their own history, audience and cueing practice. Captions are not only for Deaf audiences, although access is their primary purpose. More text is not better: a dense display can be less accessible than a concise one. And a translation cannot automatically become an access caption track without a separate edit.

A practical checklist for an international production:

• Define the purpose: translation, access, or both.
• Identify the audience languages and access needs, and decide which performances carry which text.
• Clear rights for translation, surtitle display and any recording or streaming.
• Commission translation and captioning as distinct tasks with named roles.
• Prepare a cue script and rehearse the operator with the production.
• Test screens, sightlines, font size and contrast in the actual venue.
• Brief front-of-house staff and publish clear pre-show information.
• Archive the final text, cue script and operator notes for touring and revival.

Surtitles and open captions work best when they are treated as part of the production’s dramaturgy and access planning, not as last-minute technical add-ons. The text on screen is a translation, an interpretation and an invitation to the audience; the clearer the brief, the more likely it is to serve the performance.
