How to convert text to speech in Hindi
Five steps, one decision that matters more than the other four, and the specific checks that stop a finished file having holes in it.

Converting Hindi text to speech is straightforward once one decision is made correctly. Almost every complaint about Hindi TTS quality traces back to getting that decision wrong, so it comes first.
Step 1: Decide whether your text is Hindi or Hinglish
This is the decision. It is not about how good your Hindi is — it is purely about which script your text is written in.
- Devanagari — आज हम बात करेंगे — is Hindi.
- Roman letters — Aaj hum baat karenge — is Hinglish, even though the language is Hindi.
They go through different preprocessing, because Roman-script Hindi needs to be recognised as Hindi rather than read as English. Picking the wrong one is the single most common cause of output that sounds wrong, and it takes one dropdown to fix.
Step 2: Write it the way it is spoken
Written Hindi and spoken Hindi are further apart than written and spoken English. Formal written Hindi read aloud sounds like a textbook, because it is one — the vocabulary is more Sanskritised and the sentences are longer than anything anyone says.
- Use the words you would actually say, including the English ones. Real spoken Hindi is code-mixed and pretending otherwise makes the audio sound stiff.
- Break long sentences. A clause that works on the page runs out of breath in audio.
- Punctuate for pauses. The danda (।) and the comma both act as boundaries, and they are the main control you have over rhythm.
Step 3: Handle the English words deliberately
If your Devanagari text contains Latin-script words, they are transliterated to Devanagari before generation. Without that step they would be dropped silently rather than mispronounced — there is a longer explanation of why in why Hindi TTS skips English words.
Automatic transliteration is right most of the time and wrong on brand names with a settled local pronunciation. When a name comes out wrong, write it in Devanagari yourself, spelled the way you say it. That overrides the guess.
Step 4: Choose a voice
Two options, with a real difference between them:
- A preset voice. Fastest to start with, and fine for one-off audio. Shared with everyone else using the same preset, which matters if you are building a channel.
- Your own cloned voice. A 12-second Hindi recording produces a voice you reuse for everything afterwards. Record it in Hindi — a reference in another language is measurably worse, and on the Indian-language path the mismatch is worse than merely accented.
Cloning requires a paid plan; the free tier generates English only, so Hindi generation of any kind starts on Starter.
Step 5: Generate a paragraph, check it, then do the rest
Never generate a long script first. Generate one paragraph — specifically one containing your English words, your numbers and any proper nouns — and check three things:
- Are the English words present? Listen for them specifically. A missing word does not sound like an error; it sounds like a shorter sentence.
- Are the numbers read correctly? Dates, amounts and phone numbers are where readings go wrong.
- Is the pace right? Adjust tempo rather than rewriting. Slower for explanation, neutral for narration.
Two minutes here saves discovering a hole in minute nine of a finished video.
Long scripts
Text past the per-request limit is split automatically on sentence boundaries — including the danda — and stitched back together, so long-form Hindi narration does not break mid-clause. You do not need to chunk it yourself, though generating section by section is still a better working habit because a fix then touches one file.
