How to make a YouTube voiceover

Write or paste your script. Split long scripts into scenes – that makes re-recording a single part easy.
Choose a voice: for a natural narrator use the AI voices (for example Nova, Sage or Onyx); for many languages or exact control use the regular voices.
Listen, adjust and click Download as MP3.
Import the MP3 into your editor (Premiere, DaVinci Resolve, CapCut, iMovie …) and place it under your footage.

Which voice for which video?

Explainers and tutorials: AI voices Nova, Sage or Alloy – clear and friendly.
Documentaries and storytelling: AI voice Onyx or Coral (deeper), with an instruction such as "calm, documentary narrator".
Shorts and fast edits: raise the speed slider of the AI voices, or use <prosody rate="fast"> with the regular voices.
Videos in other languages: regular voices in 28 languages and accents, or AI voices with automatic language detection (57 languages).
Dialogues: regular voices with [speaker:Brian] / [speaker:Emma] to switch speakers in one file.

Timing: pauses and pacing

Insert pauses where your video needs them, for example before a cut: <break time="2s"/>. Pauses work with both voice types (AI voices: whole seconds from 1 to 60). With the regular voices you can also stress words (<emphasis>) or slow down a key sentence (<prosody rate="slow">).

Can I monetize videos with ttsMP3 voiceovers?

Yes. You may use the MP3 files in commercial projects, including monetized YouTube videos, for free and paid usage, and you do not have to credit ttsMP3. With AI voices, please make clear to viewers that the voice is AI-generated. Details: commercial use of text to speech.

How long can my script be?
