AI Voiceover Generation

What is AI voiceover generation?​

AI Voiceover Generation converts your script into natural-sounding spoken audio.

In ReelBot, the voiceover is not just narration — it is the timing authority for the entire video.

The voice controls:

  • pacing
  • caption timing
  • visual sequencing

Everything else adapts to the spoken delivery.

Where voiceover is used​

Voiceover generation is available in:

  • Video Studio → Voiceover step
  • With Narration video type only

Cinematic / Music Only videos do not use voiceovers.

How voiceover generation works​

When you generate a voiceover:

  1. ReelBot takes the finalized script
  2. You select a voice
  3. The voice is generated using AI speech synthesis
  4. Speech marks are generated alongside the audio
  5. Voice timing is locked for downstream steps

This ensures accurate word-level synchronization.

Speech marks and caption accuracy​

ReelBot uses speech marks to track:

  • word boundaries
  • timing offsets
  • spoken sequence

This allows:

  • word-by-word caption highlighting
  • precise subtitle timing
  • consistent pacing across videos

Speech marks are the foundation of ReelBot’s caption accuracy.

Voice selection​

When selecting a voice, you’ll see:

  • voice name
  • voice type (e.g. male / female)
  • accent or locale

Available voices depend on:

  • selected content language
  • regional availability
  • quality optimization

Each language has a curated set of voices for clarity and delivery.

Voice and language behavior​

Voiceover language follows the content language, not the interface language.

This means:

  • scripts are spoken in the selected content language
  • available voices update automatically
  • accents remain appropriate to the language

Switching content language requires regenerating the voiceover.

Previewing voiceovers​

After generating a voiceover:

  • an audio player becomes available
  • you can listen to the delivery
  • pacing can be evaluated before proceeding

Previewing does not consume additional credits.

Regenerating voiceovers​

You may regenerate the voiceover if:

  • delivery feels off
  • pacing is too fast or slow
  • a different voice fits better

Regenerating the voiceover:

  • consumes AI credits
  • does not affect the script
  • preserves assets
  • regenerates speech marks and captions timing

ReelBot always warns before clearing dependent data.

Voiceover vs music​

In narrated videos:

  • music is optional
  • voice always takes priority
  • music volume is balanced automatically

Music never interferes with spoken clarity.

Voiceover and duration​

Voiceover pacing is constrained by:

  • selected duration
  • natural speech rhythm

If pacing feels rushed:

  • reduce script length
  • increase duration
  • regenerate the script and voice

Do not try to fix pacing with visuals.

What voiceover generation does NOT do​

Voiceover generation does not:

  • change the script content
  • auto-select visuals
  • auto-adjust tone
  • guarantee emotional performance
  • alter caption styling

It focuses on accurate delivery.

Best practices for voiceover generation​

For best results:

  • finalize the script before generating voice
  • listen to the preview fully
  • keep one voice per batch
  • avoid frequent voice switching
  • regenerate selectively

Voice consistency improves viewer familiarity.

Common mistakes to avoid​

  • generating voice before script is final
  • changing duration after voice generation
  • regenerating voice to fix script issues
  • ignoring preview playback

Most issues start upstream.

The CreatorOps perspective​

In CreatorOps, voice defines tempo.

By anchoring timing to spoken delivery:

  • captions stay accurate
  • visuals stay aligned
  • pacing remains predictable

ReelBot treats voiceover as a structural component — not an accessory.

  • AI Script Generation
  • Tone as an Input
  • Captions & Speech Marks
  • Regeneration & Safe Iteration

The voice sets the rhythm — everything else follows.
