Native WhatsApp Voice Notes and Transcripts in Sparkforge

By Sparkforge Support Team ·Last reviewed May 3, 2026

Sparkforge sends outbound WhatsApp voice notes in WhatsApp's native OGG/Opus format so they play inline. Recipients with transcripts enabled in their WhatsApp app can read the message as text.

Sparkforge delivers outbound WhatsApp voice notes in WhatsApp's native voice-note format. They auto-download and play inline, just like messages recorded inside WhatsApp. If the recipient has WhatsApp's voice transcript feature enabled, they can read the message as text.

Why It Matters

  • Instant playback: voice notes auto-download and play inline.
  • Optional transcripts: recipients with WhatsApp transcripts enabled can read the message.
  • Higher response rates: inline audio feels native and keeps the conversation moving.
  • Accessibility: transcripts help in noisy environments or for hard-of-hearing contacts.
  • Fewer delivery issues: native format reduces failures from unsupported attachments.

Send a Voice Note

  1. Open Conversations and select a WhatsApp thread.
  2. Click the microphone icon (web) or press-and-hold the mic (mobile) to record.
  3. Pause, resume, re-record, or delete as needed.
  4. Click Send. Sparkforge handles format conversion and delivers a native voice note.

Transcripts Are Recipient-Controlled

Transcripts are turned on by the recipient inside WhatsApp, not by Sparkforge. If transcripts are off on their device, no transcript appears.

  1. The recipient opens WhatsApp Settings → Chats → Voice message transcripts.
  2. They pick a transcript mode/language WhatsApp supports for their device.
  3. They tap Transcribe on supported voice notes.

Format and Limits

  • Format: OGG/Opus, WhatsApp's native voice-note container. Sparkforge converts automatically when you record or send from Conversations.
  • Maximum duration: 10 minutes per voice note.
  • Media availability: WhatsApp/Meta hosts media for a limited time. Very old voice notes may appear unavailable in Sparkforge's message view.
