To hear a YouTube script before recording, paste it into VoiceHue, choose a voice and listen; it is free, needs no account and takes up to 3,000 characters per part, about three minutes of narration.
Free text to speech: paste up to 3,000 characters, pick a voice and listen in your browser. The voices load in a moment.
A ten-minute video is around 1,500 words, so it splits into about four parts of 3,000 characters. Convert each part separately and keep the intro, the main points and the outro as their own parts. That also makes it easy to replace a single section later.
Listening to a script reveals long sentences, repeated words and awkward transitions that you do not notice when reading. Slow the speed a little for technical content and listen for terms that the voice mispronounces; add a respelling in the preview text if needed.
Try the same paragraph with several voices. A steady, neutral voice suits tutorials and explainers; a warmer voice suits stories. Decide before you record or edit, so the whole video keeps one voice.
Cloud voices are live: they play in the browser and download as MP3, free within the daily limits. The voices of your device also work for listening. A free developer API is available on the developers page, and one-time credit packs are planned, with no date yet (see pricing).
Even if you will record yourself, a text-to-speech preview is a fast proofreading pass. It reads exactly what is on the page, so it exposes missing words and tongue-twisters before you spend time recording.
Channels with a global audience often publish the same video in more than one language. Write the script natively for each, preview it with a voice for that language and check the timing, because Spanish and Portuguese scripts usually run slightly longer than English.
At about 150 words per minute, multiply the word count by 0.4 seconds to estimate the running time. Paste a section, listen once and compare the actual length with that estimate so your edit has no surprises.
Each conversion accepts 3,000 characters, so split a long script into parts.
