Introduction to Voices and Languages

TL;DR; Every time you generate a video in Lupo, a small dialog asks you to pick a voice, choose subtitles, and set a speed. This section is the guided tour of that dialog and the choices inside it — how to pick a voice that sounds right for your content, how to add captions in another language, and when Premium voices are worth it.

When you upload a PowerPoint (or Google Slides, or a PDF, or a video to transcribe), Lupo pops up a Select Voice dialog before kicking off the job. It's the same dialog in every Create tool, and it's where you make three decisions at once:

1. Who is going to narrate this? (voice type and specific voice)
2. What captions do you want? (subtitles in one or more languages)
3. How fast should the narration go? (speed multiplier)

Plus a couple of advanced options that most people won't need.

The voice dialog at a glance

Here's everything on the dialog, in order from top to bottom:

• Choose voice type — Standard or Premium. Premium voices sound more natural but are slower to generate and may require a paid plan. More on that in Premium Narrators.
• Choose a voice — a dropdown of specific narrators. The list changes depending on the voice type you picked. More on picking a voice in Narrators.
• Subtitles (Captions) — pick zero, one, or multiple languages for on-screen subtitles. Supported: English, Spanish, French, German, Chinese, Japanese, Arabic, Portuguese, Russian, Italian. More on captions in Translations.
• Narration Speed — a dropdown from 0.8 to 1.3 for Standard voices (0.7 to 1.2 for Premium), where 1.0 is normal.
• Advanced options — a checkbox that tells Lupo to generate voice-over from the slides even if your speaker notes are empty.
• Your email — the address that will receive the finished video. Pre-filled with your account email.
• Optional additional emails — comma-separated list of other people to copy on the final email. Handy for letting a colleague know a draft is ready.
• Confirm / Cancel — Confirm kicks off the job.

You'll see this dialog from the Create Video From PowerPoint page, the Generate Narration page, the Google Slides page, the Animations / Video Builds page, and the Transcript page. Same controls everywhere.

When to open the advanced section

The Generate voice-over if no notes are found checkbox is what lets Lupo produce a video even when you haven't written speaker notes yet. If you leave it checked, any slide with empty notes gets an AI-drafted narration on the fly. Uncheck it if you want Lupo to stay silent on empty slides — useful if you're building a montage or intentionally leaving some slides without voice.

This is different from the dedicated Generate Narration From PowerPoint tool, which writes narrations back into a .pptx file for you to review. The checkbox in this dialog is the "just do it now" version.

When captions are worth setting

Add subtitles when:

• Your audience watches videos in a second language and the written form helps comprehension.
• You need to comply with accessibility requirements.
• You want the video to be watchable with the sound off (open offices, commuting, hearing impairment).

Captions don't change the narration — the voice still speaks whatever's in the notes. They just add on-screen text.

Where to go next

• Narrators — the actual voices, how they differ, and how to audition them.
• Emotions — how to make a single narrator sound excited, calm, or serious across different slides.
• Premium Narrators — what Premium voices get you and when to use them.
• Translations — captions, multi-language output, and how to use the subtitles picker.
• Premium Tutorial — a walkthrough of producing a video with a Premium voice from start to finish.
