YouTube voiceover generator

Draft long-form and Shorts narration with neural voices. Block-based scripts, 24 kHz MP3 export, no desktop DAW required.

A YouTube voiceover is narration you generate from a written script instead of recording in a booth. MachenVoice lets educators, explainers, and documentary-style creators paste scripts in blocks, pick a neural voice, and export a 24 kHz MP3 for Premiere, CapCut, or DaVinci.

How to do it step by step

  1. 1

    Outline the video in your doc tool first, then paste the cold open into block one and the main lesson into block two (2,000 characters max per block).

  2. 2

    Select Aria (English - United States) or Guy (English - United States) and preview the same hook in both before generating full blocks.

  3. 3

    Generate block one, listen, tweak punctuation, regenerate if needed, then repeat for block two and any extra blocks.

  4. 4

    Use the in-page playlist to hear blocks in order; when the flow sounds right, export one project MP3.

  5. 5

    Import the MP3 on your timeline, align B-roll to sentence boundaries, and add chapter markers in YouTube Studio after upload.

Tips for natural-sounding YouTube narration

  • Write for the ear: one idea per sentence, contractions where a human host would use them, and commas where you want a half-beat pause.
  • Spell out numbers under ten; for years and stats, write digits only if your voice reads them cleanly in preview.
  • Put the hook in block one alone—aim for under eight seconds spoken—and move definitions to block two so viewers hear value fast.
  • Avoid ALL CAPS for emphasis; use word choice and short sentences instead so the neural voice does not shout.
  • Leave a blank line in your source doc where you want a longer pause, then mirror that with a period and a new paragraph in the block.

Which voice should I choose?

VoiceWhy it fits this use case
Aria (English - United States)Bright explainers, listicles, and weekly news-style shows with a consistent host tone.
Guy (English - United States)Slightly deeper host tone for long-form commentary and documentary pacing.
Sonia (English - United Kingdom)UK English explainers without re-writing the script for American spelling.
Ryan (English - United Kingdom)Neutral British delivery for finance, history, and policy topics.
Francisca (Portuguese - Brazil)Brazilian Portuguese explainers when the script is already in PT-BR.
Elvira (Spanish - Spain)European Spanish tutorials when you localize titles separately in YouTube Studio.

Common mistakes

  • Pasting a 6,000-character essay into one block.

    Split at scene changes; each block stays under 2,000 characters and is easier to re-record after edits.

  • Changing the voice every episode.

    Pick one voice ID per channel and document it in your Notion template so subscribers recognize the show.

  • Writing URLs as “www dot site dot com”.

    Use plain language (“link in description”) unless you tested how your chosen voice reads spelled-out domains.

  • Skipping preview on mobile speakers.

    Many viewers watch on phones; preview once on laptop speakers and once on a phone before final export.

FAQ

Can I use MachenVoice audio on YouTube videos that run ads?
Some creators use TTS in videos that later run YouTube ads, but MachenVoice does not guarantee monetization or rights. Confirm the upstream provider’s server neural TTS terms, YouTube’s synthetic-speech and monetization rules, and our Licenses page before you publish or enable ads.
How long can each script block be?
Up to 2,000 characters per block. Add more blocks for longer videos and export one combined MP3.
Does MachenVoice edit video or add captions?
No. We generate narration MP3 only. You edit video and upload captions in your NLE or YouTube Studio.
Can I use the same script for Shorts and long-form?
Yes—duplicate blocks, shorten block one for Shorts, and keep the long lesson in separate blocks for the main upload.
Will regenerated blocks match earlier takes?
Small text edits usually sound consistent when you keep the same voice ID and effect settings; large rewrites should be previewed again.
