How do I transcribe WhatsApp OPUS audio to text?

To transcribe WhatsApp OPUS audio: 1) Export the .opus file from WhatsApp (Android: WhatsApp/Media/WhatsApp Audio folder; iPhone: share the audio to Files). 2) Go to voxscriber.com. 3) Upload the .opus file. 4) Wait for transcription. 5) Copy or export the text.

Do I need to convert OPUS to MP3 before transcribing?

No. VoxScriber accepts OPUS directly, without any prior conversion. Converting from OPUS to MP3 before uploading can actually reduce quality, since it's a lossy-to-lossy conversion.

Does Telegram OPUS audio also work?

Yes. Telegram voice messages are saved as .ogg files with Opus encoding — fully compatible. Access the conversation in Telegram Web or Desktop, right-click the audio and "Download" to get the file.

Why does WhatsApp use OPUS instead of MP3?

OPUS was specifically designed for voice transmission over the internet: it compresses more efficiently than MP3 at low bit rates while maintaining good speech quality. This allows voice messages to be sent with less data.

Can low-quality OPUS (choppy voice) be transcribed?

Yes, but with lower accuracy. If the original message has excessive background noise, low volume, or very distorted voice, accuracy may drop to 70-85%. Solution: request a new message with less background noise.

Can I transcribe multiple OPUS audio files at once?

Yes. VoxScriber accepts multiple uploads in sequence. For long WhatsApp conversations with dozens of messages, batch transcription is available on paid plans.
