AI Text to Speech: Realistic AI Voice Generator

Text to speech: how AI voices work

Text to speech, or TTS, converts typed text into spoken audio. Older TTS voices sounded flat and robotic; modern AI voices read with stress, pauses and intonation that are hard to tell from a real narrator. You do not need a microphone, a studio or any software: everything runs in the browser on a computer or a phone.

One minute of English speech is roughly 900 characters, so a 3,000 character run gives you about three minutes of audio. A short ad or a paragraph for a Reel is ready in seconds, a long article takes a few runs. Download each part and join them in any video or audio editor.

AI voices read punctuation too. A period gives a finished tone and a pause, a comma a short breath, a question mark lifts the pitch, an ellipsis slows things down. The same text sounds different with different punctuation: it is the simplest way to steer the delivery without touching any settings.

Male, female and character voices

ElevenLabs has fifteen voices: eight male and seven female, all native English speakers. Brian is deep and velvety, Hank is gravelly and made for trailers, James sounds like a business presenter, Mark and Liam are young and upbeat. Among the female voices, Bella is steady and confident, Jessica is bright, Lucy is low and calm, Allison is soft and soothing.

MiniMax has thirteen voices: five native English voices (Margaret, Emily, Chloe, Daniel and Jake) and eight Russian voices that read English with a slight accent. Seed Audio has no voice list: it picks the voice and manner from your scene description.

Choose the voice for the job. A calm, clear voice suits tutorials and training, an energetic one suits ads, a warm storyteller suits audiobooks and bedtime stories. Before you voice a long script, try one paragraph with two or three voices: it is faster than redoing the whole thing.

Text to speech in Spanish and 30+ other languages

All five models read English, and ElevenLabs sounds the most natural in it. The ElevenLabs voices also read Spanish, Portuguese, French and other languages: the model detects the language of your text on its own.

MiniMax Speech 2.8 HD supports 37 languages, including Spanish, French, German, Portuguese, Italian, Japanese, Korean, Chinese, Arabic and Hindi. Seed Audio switches to its multilingual mode automatically when the text is not in English.

Need the same video in another language? The Dubbing tab translates audio and video into 16 languages and keeps the speaker’s timbre.

How to prepare a script for an AI voiceover

The AI reads exactly what you write, so a little prep pays off. Break long sentences into shorter ones: they are easier to follow, and the intonation comes out more natural. Spell out abbreviations the way they should be spoken, and write unusual acronyms as they sound.

Numbers, dates and amounts are read automatically, and ElevenLabs has a setting that reads them as words or leaves them as they are. In tricky cases write them out yourself: “May twenty-fifth” instead of “5/25”. Listen to the whole take before you publish: one wrong word is easier to fix with a comma or a synonym than by voicing everything again.

Emotions, pauses and audio tags

In ElevenLabs, delivery is set with tags right in the text: [whispers], [laughs], [sighs], [excited], [sad], [angry] and [sarcastic]. Insert them from the “Audio tags” menu in the text box; Eleven v3 plays them the strongest. The Stability setting makes the voice more expressive or more even.

In MiniMax, pauses are exact: <#1.5#> means a second and a half of silence, anywhere from 0.01 to 99.99 seconds. Interjections go in parentheses: (laughs), (sighs), (coughs), (gasps). The emotion is set in Settings: neutral, happy, sad, angry, surprised, fearful or disgusted.

If a word comes out wrong, add a comma, rephrase the line or try another voice of the same model. Eleven v4 and v4 Turbo also accept a phonetic spelling between slashes.

AI voiceover for YouTube, ads and audiobooks

For a video, download the voiceover as MP3, or as WAV for editing, and drop it on the timeline in your editor. If a person on screen speaks and the lips must match, use lip sync: it adjusts the mouth movement to the finished audio.

Ads work best with short lines and a bright delivery: Eleven v4 with low Stability, or MiniMax with the Happy emotion. Audiobooks and lectures need an even read without strong emotion. Voice chapters in parts of up to 3,000 characters with the same voice and settings, and the joins will not be audible.

Lip sync: match a video to the voice

Voice changer and your own voice

The Voice changer tab takes your recording (MP3, WAV or M4A, up to 5 minutes) and replaces the voice with one of the fifteen ElevenLabs voices. Your words, pauses and intonation stay the same, and background noise can be removed along the way.

To voice text with your own voice, open the voice picker and choose “Your own voice”. Record a short sample right in the browser or upload a file, confirm it is your voice, and it appears in the list for MiniMax or Seed Audio. A MiniMax voice is kept with no expiry, a Seed Audio voice for 12 months.

Is there free text to speech?

Yes. After you sign in, every account gets 2 free voiceovers of up to 500 characters each (up to 300 with Seed Audio), on any of the five models.

• Sign-in is required: free attempts are tied to your account.
• 500 characters is a paragraph or a short ad script.
• If a voiceover fails, the attempt is not used up and comes back automatically.
• After that, voiceovers are paid with tokens per character, and the price shows on the button before you run it. Voice changer, dubbing and your own voice are paid only.
