AI Deck webinars are narrated slide by slide. Pick a narrator from the Voice panel and click Generate Voiceover. Each slide is narrated in turn, the audio is saved into your WordPress Media Library, and the clip length is measured so the room knows exactly how long each slide runs.
The built in voices:
Nine English voices ship with the plugin: Heart, Bella, Nicole and Sarah as US female, Michael, Fenrir and Puck as US male, Emma as UK female and George as UK male. The list also carries built in voices for Spanish, Portuguese, French, Italian, Hindi, Japanese and Chinese, twenty more in all. The Narrator menu groups them by language and puts your chosen narration language first. They run in your own browser, on your own device. The voice model downloads once on first use, then generating narration costs nothing per word.
Your own cloned voice:
Install the free companion app, Results AI Voice Engine, on the same computer. Record a short sample to create a profile, keep the app running with its server and network access options switched on, then reload the webinar editor. Your profile appears in the narrator menu under My Voices. Your voice is trained and stored on your own machine.
Other languages:
The Narration language menu offers English, Spanish, French, Italian, Portuguese, German, Hindi, Japanese and Chinese. Pick a narrator from that language's group in the Narrator menu. German has no built in voice, so for German narrate with one of your own cloned voices from My Voices, which also work for every other language on the menu. When you change the language, the editor reminds you to check that the narrator you picked speaks it.
What re records everything:
Changing the narrator or the narration language clears the existing clips, because they no longer match. The editor tells you to click Generate Voiceover again to re record every slide.
Only missing slides are narrated:
Generate Voiceover narrates only the slides that do not have audio yet, so pressing it again after an edit fills in just the gaps. To redo every slide, tick Re-narrate every slide under the button first.
If some slides fail:
Generation runs slide by slide and keeps going if one fails. At the end the status line reports how many slides failed. Click Generate Voiceover again and it fills the gaps.
If your cloned voice is missing:
Make sure the Voice Engine app is open with its keep running and network access options enabled, then reload the editor. The editor retries the connection in the background, and keeps the app selected as long as it stays open while you generate. If the app is not running when you press Generate Voiceover, you are told so and can pick a built in voice instead.
