Typical throughput
Record once. Uncle’s voicelands on 500 phones.
The dadaji who is not on WhatsApp. The auntie whose blessing has to be in her own voice. The last-minute baraat timing change. Record the message. Pick the list. Every phone rings, they pick up, they hear it — same as a normal call.
No app. No smartphone required. Works on the flip phone at the chacha-ji’s factory.

The five calls every wedding still makes manually.
We asked 40 planners what call lists they still dial by hand. These five came back again and again. Voice Broadcasts exist because of them.
The elder-only blessing
The 78-year-old grand-aunt wants to bless the couple in her own voice. She records 40 seconds on the family WhatsApp. You forward it. Every guest on the main list hears her wish the couple personally.
The baraat timing change
Baraat shifted from 6 PM to 7:30 PM because the horse is stuck in traffic. WhatsApp reaches the groom's-side messaging crowd, but not the uncle with the DSLR. A 15-second call lands on every phone.
The venue-change Saturday
Reception shifted from lawn to ballroom because of rain. 600 guests en-route. You cannot send a WhatsApp and pray — you need every phone to ring in the next 20 minutes.
The elders-only reminder
The 40 closest relatives need to know the Haldi starts at 7 AM sharp, not the earlier rough estimate. A call from a familiar voice lands differently than a generic template text.
The thank-you call
Couple returns from the honeymoon. Wants to thank every guest personally. Records one heartfelt 30-second message, it goes out as a call. The uncle in Lucknow calls his son afterwards to say "the newlyweds called me directly".
The NRI callback request
Confirmed guests in the US, UK, Dubai. A voice call across an 11-hour time difference reaches them before WhatsApp does, because their phones ring even when data is off.
Three taps from recording to every phone.
Record, upload, or forward
Use the in-app recorder on desktop or mobile. Upload an MP3, WAV, M4A, AAC, or OGG file. Or forward a WhatsApp voice note from the family group — auto-converts and de-duplicates.
Pick the audience
Same segmenter as WhatsApp announcements. Bride's-side elders only. Confirmed Haldi guests. Everyone except the office list. See cost estimate update live as you narrow.

Voice Broadcast or Voice AI?
Both features make a phone ring. They’re not the same thing. Here’s how we tell planners which one to reach for.
Frequently asked questions
How is this different from the AI voice agent feature?+
Voice Broadcasts are one-way, on purpose. You record a 30-second clip — it plays for each guest when they pick up, and the call ends. It is the audio equivalent of a WhatsApp broadcast. Use it for announcements where the message does not need a response: baraat timing change, venue directions, thank-you after the wedding, elder relative's blessing message. For actual conversations and RSVP collection, use Voice AI.
What audio formats can I upload?+
MP3, WAV, M4A, AAC, OGG — anything your phone's voice recorder or WhatsApp voice note exports. We auto-convert to MP3 for the call. Length between 5 seconds and 5 minutes. We recommend under 30 seconds — past that, guests hang up.
How much does each call cost?+
Price depends on the recipient country and duration. India: roughly ₹2.60/min, so a 30-second message is about ₹1.30 per guest. US, Canada, UK, Singapore: similar. Australia, Germany, UAE and some European countries cost more. The app shows a live cost estimate before you send — 500 guests at 30 seconds is usually under ₹700 for an all-India list. Failed calls (busy, no-answer, invalid number) auto-refund.
What do guests see on their phone?+
A normal incoming call from a local or wedding-branded number. They pick up, hear the recording play out, and the call ends. Works on every phone — nothing to install, no WhatsApp required. Particularly useful for the elders-only crowd that does not use messaging apps.
Can I record directly in the app, or do I have to upload?+
Record in the app on desktop with a browser mic, on a mobile phone using the built-in recorder, or upload any existing audio file — including WhatsApp voice notes you already exchanged with the family. The uncle who is not tech-literate can send you his blessing as a WhatsApp voice message, you forward it to Weddingkart, it goes out as a call.
How do I know which guests the message reached?+
Real-time status table: completed (answered + played fully), no-answer, busy, failed, in-progress. Per-guest call duration so you can see who hung up after 3 seconds vs heard the whole thing. Exportable to Excel for the ops team.
Can I send to only part of the guest list?+
Yes. Same segmentation as WhatsApp announcements — by side (bride/groom), by group (family, close friends, office), by city, by custom tag, or handpicked individuals. The most common use: send a Haldi-morning reminder only to the 80 confirmed Haldi guests, not the 500-person main wedding list.
Is the audio file kept private or is it indexed somewhere public?+
It sits on Weddingkart's private storage — unique URL per wedding, served only to the Twilio calling infrastructure during delivery. Not indexed, not searchable, not shared. Retained for 90 days after the wedding for audit and re-send, then purged.
Record it. Broadcast it. Done in four minutes.
500 guests, one voice. No app downloads, no typing, no awkward template messages. Just a phone that rings with someone they recognise.
