What Is the Difference Between Surtitles, Subtitles and Theatre Captions?

Surtitles, subtitles and theatre captions all put words on display, but they do different jobs. In broad terms, surtitles translate staged text, usually for opera or theatre, and are normally projected above the stage. Subtitles translate or transcribe spoken or recorded material on a screen. Theatre captions provide access to scripted performance, usually for deaf, deafened and hard of hearing audiences, and are prepared and cued live by a captioner. The overlap is real: Stagetext notes that the words are often used interchangeably in everyday life, while distinguishing three production workflows in its own work (Stagetext, ‘What’s the difference between captions and subtitles?’).

Three jobs, not one

At Stagetext, a deaf-led charity, 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. All three are described as verbatim, accessible text that allows deaf, deafened and hard of hearing people to be included (Stagetext, FAQs).

Surtitling is not identical to any of these. It is primarily a translation practice for staged performance, most often associated with opera. A Routledge chapter on surtitling and captioning for theatre and opera notes that surtitling originated as a service in opera and that, for opera-goers, surtitles provide the translation needed to understand text written in another language (‘Surtitling and captioning for theatre and opera’, Routledge, 2018).

Surtitles: translation above the stage

Surtitles — sometimes called supertitles — are the translated text that audiences read during a performance. They are most familiar in opera, where a work may be sung in Italian, German, French or another language while the audience reads a translation in English or another language. They may appear above the proscenium, on a side screen, or on seat-back displays, depending on the venue.

The Routledge chapter notes that interlingual surtitles can address source-language audiences, target-language audiences, or audiences with knowledge of both languages. That is a useful reminder that a surtitle is not only a linguistic aid. It also shapes who the production is speaking to and how different parts of an audience experience the same performance.

Because surtitles are read while music and staging continue, they are usually condensed and carefully timed. Their main purpose is linguistic: they translate staged text. A surtitled performance is not automatically captioned for deaf and hard of hearing audiences, because surtitles may not include the sound information, speaker identification or access planning that captioning provides.

Subtitles: screen, stream and live speech

In screen media, subtitles are text timed to dialogue or commentary. They may translate foreign-language dialogue, or they may provide same-language access to speech and sound. Stagetext uses the term digital subtitling for pre-recorded videos prepared by a digital subtitler, and live subtitling for unscripted speech produced live by a speech-to-text reporter (Stagetext).

That distinction matters in theatre because a recorded trailer, a streamed archive, and a live post-show talk may each require a different workflow. A digital subtitle file can be prepared, checked and corrected before release. Live subtitling has to keep pace with speech as it happens, which introduces different pressures of accuracy, delay and display.

Subtitles can be open, always visible on screen, or closed and selectable by the viewer. In digital platforms, they may be embedded in the video or supplied as a separate file. Subtitling is therefore not limited to translation: in accessibility contexts, same-language subtitles can convey dialogue and important sounds, and Stagetext treats digital subtitling as part of access provision.

Theatre captions: access for scripted performance

Theatre captioning is designed for scripted performance. A captioner prepares from the script, then cues the text live in sync with the performance. Stagetext describes theatre captioning as ‘prepared and cued live by a theatre captioner’ and groups it with verbatim accessible text for deaf, deafened and hard of hearing people.

In practice, captions may be shown on screens at the side of the stage or on individual displays. They can include character names, speaker changes and descriptions of significant sounds, depending on the provider and production. The key point is that captioning is an access service: it is not simply a translation projected above the stage. A captioned performance should be advertised as such, and the captioning should be checked for sightlines, readability and sync.

How the three compare

Why the distinction matters

The terms are not decorative labels. They signal a service. If a venue advertises surtitles, audiences may expect translation. If it advertises captions, they may expect access. Using the wrong term can mislead audiences and obscure the labour involved. A captioner is not a translator, and a speech-to-text reporter is not a digital subtitler. The skills, preparation and live delivery are different.

Stagetext states that captions and subtitles are used so that ‘the one in five of us who need them’ can experience live theatre, musicals, museum tours and author events (Stagetext, FAQs). Access is therefore not a niche add-on. Major venues also run access schemes that include accessible seating and assistive hearing devices; these sit alongside captioning and surtitling, not in place of them (Royal Ballet and Opera, Accessibility).

Practical choices for producers

• Define the job. Is the text translating a foreign-language work, giving access to same-language dialogue, or both? The answer determines the service, the provider and the audience information.
• Match the workflow to the content. Scripted performance calls for theatre captioning; unscripted speech calls for live subtitling; pre-recorded video calls for digital subtitling. Surtitles are for translated staged work.
• Budget for preparation and live delivery. Translation, adaptation, cueing, rehearsal, equipment and an operator are separate costs. A text file alone is not a captioning service.
• Check rights and permissions. A surtitle script is a translation. Producers should verify translation and adaptation permissions with the rights holder or agent, and check the contract and jurisdiction. The exact route depends on the work, the territory and the agreement.
• Design for readability. Sightlines, screen position, font size, contrast, line length, reading speed and latency all affect whether text works in the room or on a stream.
• Rehearse the cues. A captioner needs a script and cue points; a live subtitler needs a clear audio feed and preparation. Build technical checks into technical rehearsals.
• Advertise accurately. Label a performance ‘captioned’, ‘surtitled’ or ‘live subtitled’ only when the service is confirmed. Audiences plan travel and tickets around those promises.
• Archive the text. Keep caption scripts, subtitle files and cue sheets as documentation, especially for touring, remounts and digital archives.

Multilingual theatre and the politics of translation

Surtitles are translations, and translations make choices. A literal rendering may preserve syntax but lose humour; an idiomatic rendering may land better but move away from the source. The Routledge chapter frames surtitling as something that can be explored from textual, ideological and technical perspectives, which is a useful reminder that timing and projection are part of meaning-making, not neutral delivery.

For bilingual audiences, the choice of language is also a choice of address. A festival audience may include speakers of the source language, the target language, or both; the same surtitle can serve different groups differently. Producers should therefore ask who the surtitles are for, not only what language the production is in. The same question applies to captioning: a captioned performance in a multilingual context may need a translated caption script, a same-language access script, or both, depending on the audience and the production.

Digital and hybrid performance

Digital performance adds another layer. A pre-recorded stream may use digital subtitling prepared after filming; a live stream or online talk may need live subtitling by a speech-to-text reporter. In both cases, the text must be timed, positioned and tested on the platforms audiences actually use. If a theatre records a captioned performance for archive, the caption file and cue sheet are part of the documentation; without them, the access service is hard to reproduce. Hybrid productions may need more than one text track: translation for one audience and same-language captions for another.

Common misconceptions

A working rule of thumb

Use surtitles when the main problem is language; use captions when the main problem is access to scripted sound and speech; use subtitles when the text is tied to a screen or recording. When a production crosses borders and audiences, it may need more than one. The terms describe different preparation, different labour and different promises to the audience.
