How do I add AI narration to PowerPoint?

Generate audio for each slide's speaker notes using Sarvam. Download as MP3. In PowerPoint: Insert > Audio > Audio on My PC. Place the audio clip on each slide and set it to play automatically. Or record the deck as a video (File > Export > Create a Video) with the narration baked in.

Does this work with Google Slides?

Yes, with one extra step. Upload your generated MP3 files to Google Drive. In Google Slides: Insert > Audio > select the file from Drive. Set to auto-play. Google Slides requires the audio files to be in Drive, not uploaded directly.

How much narration fits in the free tool?

2,500 characters per generation. A typical slide needs 50-150 characters of narration. The free tool handles about 15-50 slides per generation, enough for most decks.

Can I narrate the same deck in Hindi and Tamil?

Yes. Write or translate your slide notes into Tamil, generate narration, and embed the Tamil audio into a copy of the deck. One deck becomes a Hindi version and a Tamil version in under 30 minutes total.

Which voice works best for business presentations?

Riya (professional, clear) and Arjun (authoritative) are popular for corporate presentations. For warmer, more conversational decks, try Meera. Preview voices on the free tool to find the right tone for your brand.

Your slides should speak when you can't

Sales decks sent without context get skimmed and ignored. Add voice narration in Hindi, Tamil, or any of 11 Indian languages. Your pitch lands even when you're not in the room.

Narrated decks tell the full story

Context

Your best slides need your voice to land

Slide 7 has a pricing comparison that needs 30 seconds of explanation. Slide 12 has an architecture diagram that makes sense when you talk through it. Without narration, these slides confuse instead of convince. Voice narration adds the context that turns slides into a story.

Scale

You can't be in every meeting

A sales team of 10 reps sends 50 decks per week to prospects across India. Not every prospect gets a live walkthrough. The decks that do get a narration track close better than the ones sent as silent PDFs. AI narration means every deck gets a voice, not just the ones you present live.

Languages

One deck, multiple language versions

A product presentation for a pan-India client needs to work in Hindi for the Delhi office and Tamil for the Chennai team. Recording yourself in Tamil isn't an option. AI narration in 11 Indian languages makes multi-language presentations practical.

Narrate a full deck in 15 minutes

Export your slide notes

Copy the speaker notes or talking points for each slide. These become your narration script. Most decks already have notes written. If not, write 2-3 sentences per slide.

Generate audio per slide

Generate a voice narration for each slide's notes. Pick a professional voice. Adjust pace: slower for complex diagrams, normal for text-heavy slides.

Embed audio in your deck

Insert the generated MP3 files into PowerPoint (Insert > Audio > Audio on My PC) or Google Slides (Insert > Audio). Set each clip to play automatically when the slide appears.

Share and let the deck do the talking

Export as PowerPoint with embedded audio, or record the deck as a video with narration baked in. Share via email, Slack, or your CRM. The prospect hears your pitch without scheduling a call.

Where narrated presentations win

Sales decks and proposals

The strongest use case. A narrated product deck sent to a prospect outperforms a silent PDF every time. The prospect hears your value prop explained, sees the pricing walked through, and understands the implementation plan. Without scheduling a 30-minute call.

Company townhalls and updates

A CEO quarterly update for a company with offices across India. Record the narration once in Hindi, generate Tamil and Telugu versions for regional offices. Every employee hears the update in their language, not just the ones who understand Hindi.

New hire onboarding decks

HR onboarding decks explain company policies, benefits, and processes. Adding voice narration means new hires absorb the information at their own pace, in their language. No HR team member needs to repeat the same presentation 50 times per quarter.

Product training for partners

Channel partners and resellers need to understand your product. A narrated training deck they can replay beats a one-time Zoom call. Generate in multiple languages for partners across India.

Why async presentations need voice

The remote shift

Remote work changed how presentations are consumed. Fewer live meetings, more decks shared over email and Slack. But a deck without voice is a story without a narrator. The presenter's context, emphasis, and explanations are lost. For pan-India organizations where teams speak different languages, the challenge is doubled. AI narration makes it practical to give every shared deck a voice, in every language the audience speaks.
