Assisted voice-over

How can you obtain intelligible synthetic narration that suits a video and can be used within an authorised framework?

1250 € per session, excl. VAT

In short

In a half-day session of 3 hours explore speech synthesis and create a short narration for a fictional video. You will prepare the text, compare outputs, correct audible flaws and export a file accompanied by its terms of use and a quality control checklist.

Why this training?

Synthetic narration can sound fluent while still mispronouncing a name, swallowing an instruction or running longer than the visuals. Preparing the text for spoken delivery and listening to each version avoids confusing rapid generation with a usable audio track. Choosing a voice also involves rights and responsibilities. The course distinguishes between a voice offered under licence and impersonating a person, then addresses consent, transparency notices and deepfake risks before any release. Running case study: The fictional association « Avelune Patrimoine » is preparing a 60-second video presenting an imaginary exhibition. Participants must produce a welcoming narration, pronounce two invented names correctly and respect three visual cues, without impersonating a real person. Application at work: Reuse the annotated script and listening assessment checklist on a short video for your organisation, once the rights have been approved. Compare an initial generated version with a corrected version, noting duration, pronunciation errors and passages that are difficult to understand.

Objectives of this training

  • Distinguish between speech synthesis, human voice recording and voice cloning.
  • Adapt a written text for a 60-second spoken delivery.
  • Generate two trial versions using a voice authorised for use.
  • Identify and correct flaws in diction, rhythm and pauses.
  • Export an audio track and document its terms of use.

Who is it for and what are the prerequisites?

Roles and tasks concerned

  • Communications officers preparing short videos.
  • Learning content designers wishing to explore synthetic narration.
  • Beginners in video editing who need to integrate a spoken audio track.

Prior skills

  • No prior AI knowledge required.
  • Ability to open, save and locate an audio file on a computer.

What you will work on

  1. Listen and set boundaries

    Objective: Recognise the uses and risks of a generated voice. The text-to-speech principle, expressive limitations, rights to the text and voice, consent, transparency and deepfakes.

  2. Write to be heard

    Objective: Prepare a short script timed to the visuals. Short sentences, numbers written out for spoken delivery, punctuation, breathing pauses and pronunciation guidance according to the available options.

  3. Generate and compare outputs

    Objective: Achieve intelligible narration through guided trials. Choosing an authorised voice, settings available in the tool, segmentation and correction of problematic passages.

  4. Check and prepare for release

    Objective: Check the track before integrating it into the video. Headphone listening, duration, cut-offs, silences, export format compatibility and disclosures appropriate to the context.

What you take away

  • Annotated spoken script with pauses and visual cues.
  • Two audio trial versions and an exported final track.
  • Completed comparative listening assessment checklist.
  • Release sheet: rights, voice provenance and planned disclosure.

Method and assessment

  • Short explanations followed by immediate practice on the running case study.
  • Individual work followed by work in pairs, with peer review of the outputs.
  • Guided group discussion: what works, what needs correcting and what remains a human decision.
  • Preparation: Arrange a computer, headphones and tested access to a tool authorised by your organisation that supports speech synthesis and audio export. Prepare a fictional storyboard, an original text and the terms of use for the available voices; no personal recording is required.

Observable criteria: The narration lasts between 55 and 65 seconds and respects the three storyboard cues. ; The two invented names are pronounced in accordance with the script guidance. ; No word is cut off; pauses make the sentences understandable. ; The comparison records at least two audible corrections between the trial versions. ; The release sheet documents the verified rights and the proposed synthetic voice disclosure..

Frequently asked questions

Do you need to clone your voice?

No. The exercise uses a voice offered with appropriate usage rights. No cloning or impersonation of a real person is practised.

Can you use a work-related text?

Only if it is anonymised, authorised and non-confidential. The fictional case study remains the shared working material.

Is the track automatically cleared for release?

No. Check the licence, the rights to the text and the transparency obligations applicable to the release context.

Will you produce a complete video edit?

No. The main deliverable is a checked audio track; its timing is verified against the storyboard.
