Beyond Hindi: Captioning for Tamil, Telugu, Marathi and Bengali

A creator who has solved Hindi and Hinglish captions often assumes the rest of India is a copy-paste. It is not. Tamil, Telugu, Marathi and Bengali audiences are large, commercially serious, and each brings genuine technical differences to captioning. Treating them as variants of Hindi produces captions that native readers immediately recognise as careless.

What actually changes, script by script

Marathi: the cheap win, with a catch

Marathi uses Devanagari, so your Hindi typography settings transfer almost unchanged. The catch is editorial rather than technical. Marathi code-mixes with English differently from Hindi, uses different everyday vocabulary, and a Hindi-trained transcription model will quietly substitute Hindi words that a Marathi speaker would never use. The captions look right and read wrong.

Bengali: dense conjuncts

Bengali has a large inventory of conjunct forms, and they are visually dense at caption size. Breaking a line inside a conjunct produces a shape no reader recognises, so line breaking must be word-aware. Bengali also carries marks above the baseline, so it needs the same generous leading as Devanagari.

Tamil: wide glyphs, long clusters

Tamil glyphs are comparatively wide and syllable clusters run long, which means fewer words fit per line than in Hindi at the same point size. The common failure is keeping a four-word-per-line rule from an English preset; in Tamil that regularly overflows the safe area. Two to three words per line is often the correct limit.

Telugu: stacked marks in both directions

Telugu places marks both above and below the base character, sometimes simultaneously, so it needs the most vertical room of the five. It is also agglutinative — a single written word can carry what English expresses in four or five — which makes word-level caption timing genuinely harder. One long Telugu word may span two seconds of audio, and highlighting it as a single unit feels sluggish.

Font strategy

Do not look for one font that covers everything. A single family covering five Indic scripts will be a compromise in at least three of them. Choose one well-engineered family per script, and pick them so their weights and x-height relationships feel consistent — that consistency is what makes a multilingual channel look like one brand.

• Require a real bold weight for every script. Synthetic bold destroys Indic letterforms far more visibly than Latin ones.
• Check that the family includes the conjunct forms your language actually uses, not just the base characters.
• Pair each Indic face with a Latin companion, because code-mixing means English words will appear in the same line.
• Verify rendering on an actual Android device. Indic text shaping still varies between platforms more than Latin does.
• Keep one caption preset per language rather than one preset with a font swap — line height and stroke differ too.

Transcription quality is not uniform

Speech recognition quality across Indian languages is uneven, and it broadly tracks how much public training data exists. Hindi is best served. Bengali, Tamil and Telugu are usable and improving. Regional accents within each language add another layer of variance — Telangana Telugu and coastal Andhra Telugu are not interchangeable inputs.

1. 1Expect to edit more in the first month of a new language than you ever did in Hindi. Budget the time rather than being surprised by it.
2. 2Build a per-language dictionary of names, brands and technical terms — this is where automatic transcription fails most visibly.
3. 3Never machine-translate a Hindi script and caption the translation. Write or record in the target language and transcribe that.
4. 4Have a native speaker review the first five videos in a new language before you publish at volume.
5. 5Keep the code-mixed English exactly as spoken. Tamil-English and Telugu-English mixing is as normal as Hinglish.

Should you expand at all?

Adding a language multiplies your production work, so it should be a deliberate decision rather than an experiment. Three conditions make it worth it.

• Your analytics already show meaningful viewership from a region whose language you are not serving.
• You or someone on your team speaks the language natively. Outsourcing voice to a translator is where authenticity dies.
• The topic genuinely travels. Product reviews and how-to content travel well; culturally specific humour rarely does.

If only the first condition is true, captions in that language on your existing content are a much cheaper first step than producing separate videos. Start there and see whether the engagement justifies more.
