Transcribe Twilio call recordings long conference bridges included.
To transcribe a Twilio call recording, fetch the media file from the Console or the Recordings API and upload it here; a 4-hour conference bridge comes back as text in about 8 minutes. The first 20 minutes are free, and that bridge (240 minutes) fits the $6 pack of 500 minutes with 260 to spare.
From a Recording SID to text
Your app stores every call as a recording resource. Reading one should not need a new service.
Fetch the media
Each recording is a resource with its own SID, listed in the Console's call logs and in the REST API. Per Twilio's documentation the media URL returns WAV by default and MP3 when you request the .mp3 extension; check the current docs, since formats and options can change. Your account credentials are needed to fetch it.
Upload what you fetched
Telephone WAV at 8 kHz, 16-bit mono is about 57.6 MB an hour, and dual-channel doubles it to roughly 115 MB. A 4-hour dual-channel bridge is about 461 MB, just inside this box's 500 MB. Larger files continue on the main upload page, still up to 10 hours or 5 GB; MP3 is far smaller.
The monthly arithmetic
One 4-hour bridge is 240 minutes, so the $6 pack of 500 covers it. Thirty one-hour support bridges in a month come to 1,800 minutes, inside the $12 pack of 2,000. A product that records 4,000 minutes of calls a month belongs on the $24 pack of 5,000.
What you can build on it
Download JSON with timestamps for your own tooling, SRT or VTT for playback, DOCX for a human reader. The brief, chapters and listed numbers make a long bridge reviewable without anyone replaying it. Dual-channel files keep both legs of the call in one transcript, and the people on it are named in the summary, key quotes and chapters.
Stored is not searchable
Developers keep recordings because they might need them. Then nobody can find the moment that matters.

FAQ
Twilio recordings, answered.
How long does a 4-hour Twilio recording take?
About 8 minutes, at roughly 2 minutes per audio hour. The public proof at /proof/long-files shows a 9.31-hour file done in 1,033 seconds.
Can WhipScribe pull recordings from my Twilio account?
No. It has no Twilio integration, no webhook and no access to your account. Fetch the media yourself, then upload it or share it from a Google Drive folder.
WAV or MP3, which should I send?
Either. WAV keeps everything but is larger; MP3 is a fraction of the size and fine for speech. Before your first pack, keep each file under 2 GB. A 4-hour bridge as MP3 at 64 kbps is about 115 MB, a quarter of the dual-channel WAV.
What about consent?
You need the consent the law where you are requires before recording a call. If your application records calls, make sure callers are told.
What does a busy month cost?
Under 500 minutes is the $6 pack, up to 2,000 is the $12 pack, and up to 5,000 is the $24 pack. Credits are bought once and never expire.
Is the audio used to train models?
No. Recordings are transcribed on our own servers and are never used for training. Delete the file and its text from your account whenever you like.
