E-learning voice-over with AI: a workflow for Articulate Storyline and Rise
Course narration used to mean a studio session and, for every later change, another one. With an AI voice you keep the script, change the sentence that changed and generate a new file. Here is a workflow that fits authoring tools such as Articulate Storyline 360 and Rise 360.
1. One script block per slide
Write the narration in a spreadsheet or document with one row per slide or lesson block: module, slide, text. This keeps each audio file short, lets you change one slide without touching the others, and makes it obvious when the text and the slide no longer match.
2. A naming convention
Name each file after its place in the course, for example m03-s07-intro.mp3. When you replace a file later, you will find the right one in seconds, and so will a colleague.
3. Choose one voice for the course
Learners listen for a long time, so choose a calm, clear voice with a moderate pace and keep it for the whole course. Test two or three voices with a real slide, not a single sentence. For British or American learners, match the accent: see British accent voices and American English voices.
4. A pronunciation list
Courses are full of product names, acronyms and terms a voice cannot know. Listen to them once, decide how each is read, and write it that way in every script, or set the stress in the editor. Keep the list next to the scripts, so every module sounds the same.
5. Export and import
Export each block as MP3 or WAV. In Storyline 360, add the file to its slide as audio from file; the slide timeline then follows the length of the narration, and you can align animations to it. In Rise 360, add an audio block to the lesson and upload the file. Other authoring tools and learning platforms work the same way: they accept common audio formats, one file per slide or block.
6. Updates without a studio
When a process, a form or a product name changes, edit the affected rows, generate only those files again and replace them in the course. The voice is the same, so the new slide sounds like the rest of the module.
How much text is a course?
As a rule of thumb, one minute of narration is about 1,000 characters, so a 20-minute module is about 20,000 characters. For a full course, count the characters of all scripts and add some room for revisions.

Common questions
Which format should I export for Storyline or Rise? MP3 keeps the course small and is accepted by common authoring tools and learning platforms; WAV works too.
Can I narrate the same course in several languages? Yes. Translate the scripts, have a native speaker check them, and voice each language with a suitable voice.
Can I use the narration in a paid course? Yes. Audio from any paid plan or character pack may be used commercially.
