AI text to speech for video
Paste a script, pick a voice, generate spoken audio in the browser, and download an MP3 you can drop on a timeline.
Pixwit AI text to speech lives on this page: write or paste narration, choose a speaker and language, preview the take, then export. It is for YouTube explainers, product demos, course modules, ads, and internal walkthroughs when you need spoken audio without booking a studio. Sign in to generate; credits are billed per 1,000 characters, with a 2,500-character cap per run.

How to generate a voiceover from a script
Paste Your Script
Drop in the narration, dialogue, or on-camera copy you want spoken. Use short sentences, clear punctuation, and one idea per line when pacing matters. Spell out numbers the way they should be read, and add a phonetic hint in parentheses for unusual names. Stay under 2,500 characters per run; split a long chapter into several takes.
Choose a Voice and Settings
Pick a speaker that matches the language of the script—English, Chinese, Japanese, French, Spanish, or German—and a male or female delivery. Open advanced settings if you need the stability slider: lower values sound more varied, higher values stay calmer and more consistent. Then generate. You must be signed in; cost is 12 credits per 1,000 characters, rounded up.
Preview and Download
Listen all the way through before you export. If a word lands wrong, fix the spelling or punctuation and regenerate that passage rather than stretching the take in an editor. When the pacing feels right, download the MP3 for a timeline, slide deck, or podcast. Keep the source script so you can recut later.
Voiceovers without a recording session
Natural spoken delivery
Neural voices read punctuation, questions, and short pauses in a way that is usable for explainers and product walkthroughs—not a flat robotic drone. You still write like a narrator: conversational, concrete, and free of stage directions the model would speak aloud. A clean script is the fastest path to a take you can publish.
Fits real production, not just demos
Use the MP3 under B-roll, screen recordings, slideshows, and short-form clips. Teams ship drafts to stakeholders the same day instead of waiting on a booth. When a line changes, regenerate that paragraph instead of re-recording an entire session. That loop is the reason this tool sits next to Pixwit’s video tools rather than as a novelty widget.
MP3 you can drop on a timeline
Each successful run exports an MP3. Import it into Premiere, CapCut, DaVinci, Final Cut, or a simple audio editor. Match levels to music and room tone as you would with any voice track. For a talking head, generate audio here first, then take the same script into Pixwit’s avatar or video tools.
Browser workflow, six languages
No desktop suite and no microphone calibration. Chrome or Edge on desktop is the most reliable path. Voices cover six languages, so a campaign can ship a second-language cut from a translated script. Always match the voice language to the text; mixing them is the most common cause of odd pronunciation.
How to get a usable take from written copy
Speech synthesis is only as good as the words you feed it. Creators look for AI text to speech for video when they need a draft voiceover the same day. This guide covers script craft, voice choice, credits, and how the export step fits a real edit. Use the workbench above for the generate-and-listen loop; use the notes below so you are not guessing why a take sounded rushed or flat.
Write for the ear, not the slide deck
A blog paragraph often fails when read aloud. Cut nested clauses. Prefer verbs over stacked nouns. Read the copy yourself: if you run out of breath, the model will too. Mark questions with a question mark so the pitch lifts. Avoid ALL CAPS, emoji, and markdown the engine might vocalize. For acronyms, decide whether you want letters or a spoken word, and write that choice into the script. A 2,500-character block is a short scene, not a full episode.
Pick voice, language, and stability on purpose
Choose the language that matches the script first, then the speaker. English options include Sarah, Brian, Jessica, and George; other languages have their own male and female options. Raise stability for tutorials and product specs; ease it down when a social hook needs more color. If two takes of the same line feel identical, edit the words instead of chasing the slider.
Credits, length, and when to split a script
Pricing is 12 credits per 1,000 characters, with partial blocks rounding up. A 200-character hook costs one block; a 1,001-character scene costs two. The 2,500-character ceiling keeps a single request from stalling and keeps QC manageable. For a ten-minute lesson, split by section, generate, then concatenate in your editor with a few frames of silence between chapters. Sign in so the run can attach to your credit balance. New accounts can test with signup credits before buying more on the pricing page.
From MP3 to a finished video
Treat the file like any other voice track. Lay it on a timeline, spot-check breaths and names, then cut picture to the audio rather than stretching speech to match a locked cut. If you need captions, generate them from the same script so spelling stays consistent. This page does not output a full mix with music and sound effects; pair the MP3 with picture in your editor or Pixwit’s video tools.
When a human narrator is still the right call
Use a recorded talent when the brand voice is a known person, when emotion has to land on a specific syllable, or when the legal review requires a named performer. Generated audio is a strong draft and a strong final for many explainers, but it is not a substitute for a talent contract or for accessibility review. Always listen to the completed file before it goes live. That last pass catches homographs (“read” vs “read”), skipped commas, and names that still need a respell.

Where a script-to-voice workflow actually ships
YouTube explainers and product walkthroughs
Lock the outline, paste the narration, and export audio before you animate screens or B-roll. Iterate on the first 15 seconds until the hook is clear, then generate the rest of the chapter. Audio first, picture second is how most explainer channels already work; this page just removes the booth.
Ads, landing-page clips, and social cuts
Short paid and organic clips need a confident read without a full-day session. Generate a 15–30 second VO, drop it under product footage, and recut the line when legal or the client changes a claim. Keep a spreadsheet of the exact script version that shipped so the next variant stays consistent.
Courses, onboarding, and internal demos
L&D and product teams often have slide notes that were never meant to be spoken. Rewrite those notes for the ear, generate section by section, and attach the MP3 to the LMS or an unlisted video. When a feature ships, regenerate only the changed module instead of re-recording a 40-minute course.
Second-language cuts from a translated script
If you already have a professional translation, select the matching voice language and generate a parallel track. This is not a substitute for a native reviewer: have a speaker of that language listen for names, units, and tone. Then you can publish a Spanish or Japanese cut without waiting on a second studio booking.
