What is Qefro Voice Studio?

Qefro Voice Studio is a text-to-speech web app at voice.qefro.com. It converts written text into spoken audio with Qefro’s own TTS engine, then lets you play and download that audio. It does not use the browser’s speech synthesizer or a third-party voice API.

To convert text to speech, type a script, choose a language, choose the voice the engine lists for that language, and click Generate voiceover. Each language has one voice. The engine accepts the text, the language, and the audio format. Qefro Voice Studio is a Qefro product at voice.qefro.com.

Facts checked 11 November 2026 against the Qefro TTS engine.

  1. Enter your text. Type or paste a script, up to 500 characters as a guest and 2,000 per request for an account. The engine stops at 2,000 characters.
  2. Choose a language and voice. Pick one of the 44 languages. Each language has one voice. Hear it by generating, not from a separate preview clip.
  3. Generate and download. Click Generate voiceover, play the result, then download WAV or OGG. There is no speed or pitch step, because the engine does not offer those controls.
44 LANGUAGES

Languages you can speak aloud.

These are the languages the Qefro TTS engine reports today. Hindi and English use Supertonic-3. Tamil and the other Indian languages in the first group use VITS. Mixed scripts are split by the engine. PocketTTS speaks English islands inside a mixed sentence. You cannot pick that model separately.

VITS, 24 kHz

Supertonic-3

Automatic detection is also available. Gujarati, Odia, and Urdu are not in this engine. The in-studio list is loaded from the engine, so it stays aligned when the engine changes. Each language also has its own page.

All language pages · Tamil · Hindi · English · Telugu · Bengali · Malayalam

WHERE THE AUDIO GOES

One generator, a few real jobs.

The same WAV or OGG file is what you download. The studio does not turn books, PDFs, or chat messages into audio.

Short voiceovers

Narration for a reel, a lesson intro, or a product clip in the language your listener speaks.

Pronunciation

Paste a sentence and hear how the Qefro engine reads it. Useful for Tamil, Hindi, English, and the other supported languages.

Announcements

Shop messages, hold text, and short notices. Keep each request inside the character cap.

Can I change speed or pitch?+

No. The Qefro TTS engine accepts text, language, and format only. Qefro Voice Studio hides speed, pitch, and voice-style controls because the engine does not offer them.

How much does Qefro Voice Studio cost?+

Can I use the audio commercially?+

Commercial use depends on the licenses of the VITS, Supertonic, and PocketTTS models running in the Qefro TTS engine. Review those model licenses before you publish the audio.
