Write it the way you want it said

Most text to speech sounds robotic for one reason: the words are right but the timing and stress are wrong. Auditext gives you three controls that fix that, straight in the text box:

  • Exact pauses. [pause 1s] drops a precise silence into the audio. Use it before a punchline, after a question, or between slides.
  • Emphasis. *never* tells the voice which word carries the meaning. Try the sentence on the right to hear why that matters.
  • Delivery direction. Pick a preset like Narrator or Energetic promo, or type your own direction — “a calm museum audio guide, unhurried” — and the voice acts it out.

Blank lines become natural paragraph breaths, and the pace slider goes from 0.7× for language practice to 1.5× for quick previews.

Which word carries the stress?

Tap a word. Same seven words, a different meaning each time — and a different sound.

Means: I flatly deny ever saying it.

In Auditext you mark this with asterisks: I never said *she* stole my money. Tapping plays a rough version with your device voice; the AI voices do it far more naturally.

Who uses it, and how

Creators making voiceovers

Draft the narration for a YouTube explainer, a TikTok or a product demo, time it with the word counter (about 150 words per minute), and export an MP3 you can drop straight onto your editing timeline. If you need the words too, the voiceover script writer drafts a script sized to your video length.

Presenters and trainers

Record consistent narration for slide decks and e-learning modules without booking a booth. Put a [pause 2s] where each slide changes so the audio lines up with your transitions.

Language learners

Set the language, choose the “Slow & clear” delivery, and add a pause after each phrase to shadow it out loud. Our language pages have ready-made practice scripts for Spanish, French, German, Japanese and a British English accent.

Readers and proofreaders

Hearing your own writing read back is one of the most reliable ways to catch clumsy sentences and missing words. For long articles or whole PDFs, Read Aloud follows along word by word and has no length limit.

Why modern AI voices sound human

Older speech engines glued together recorded snippets of sound, which is why they sounded choppy. Neural voices instead predict the whole sound wave from the text, learning from thousands of hours of real speech where people breathe, which syllables they lengthen and how their pitch falls at the end of a statement. That is also why they can follow a direction like “sound excited”: the model has heard what excitement does to a voice.

We built a step-by-step explainer that runs your own sentence through each stage, from expanding “Dr.” and “$4.50” into words to shaping the melody of the sentence. ahaboo takes a similar approach, with clickable explainers grounded in trusted sources that walk you through how things actually work.

The voices here come in two broad registers — 14 sit higher, 16 lower — each with a character such as Firm, Breezy, Gravelly or Warm. Browse and audition them all in the AI voice generator.

Questions people ask

Is Auditext text to speech really free?

Yes. You can render up to 5,000 characters at a time with the AI voices and download the MP3, with no account and no watermark. A fair-use limit per hour keeps the service available for everyone. The device-voice mode is unlimited because it runs entirely on your own phone or computer.

Can I use the MP3 files in YouTube videos or commercial projects?

The audio you generate is yours to use in videos, podcasts, presentations, courses and ads. The voices are synthetic and not modelled on real people, so there is no likeness to clear. Check the rules of the platform you publish on; some require you to label AI-generated voices.

How do I add a pause or stress a word?

Type [pause 1s] (or [pause 500ms]) anywhere in your script for an exact silence — Auditext inserts it into the audio itself, so it is precise to the millisecond. Wrap a word in *asterisks* to have the voice stress it. A blank line between paragraphs adds a 0.6-second breath.

Which languages are supported?

The AI voices speak more than 100 languages. The language menu lists the most requested ones, including US and British English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, Korean, Mandarin Chinese, Hindi and Arabic; choose "Detect from text" for anything else.

Can I upload a PDF or Word document?

Yes. Upload a .txt, .pdf or .docx file and the text is extracted in your browser — the file itself is never uploaded. Scanned PDFs that are only images of pages contain no text, so they need OCR first. For long documents use the PDF to Audio page, which lets you pick pages.

What is the difference between AI voices and device voices?

AI voices are generated on a neural speech model through Vercel AI Gateway: they sound natural, follow delivery directions and can be downloaded. Device voices are the ones built into your operating system: unlimited, private and instant, but more robotic, and browsers do not let websites record them, so there is no download.

How long can my text be?

Each AI render takes up to 5,000 characters, roughly 800 words or five to six minutes of speech. For longer projects, render chapter by chapter; the word counter shows the estimated spoken length before you render.
