Twilio: How to Transcribe a Recorded Dialed Call?

Are you tired of manually transcribing recorded calls, wasting hours of your precious time? Do you wish there was a way to automate this tedious process and focus on more important tasks? Look no further! In this article, we’ll guide you through the step-by-step process of transcribing a recorded dialed call using Twilio, the leading cloud communication platform.

Prerequisites

Before we dive into the tutorial, make sure you have the following:

• A Twilio account (sign up for a free trial if you don’t have one)
• A Twilio phone number or a client that can make and receive calls
• A recorded call in WAV or MP3 format
• A programming language of your choice (we’ll use Python in this example)

Step 1: Set Up Your Twilio Account

If you haven’t already, create a Twilio account and set up a new project. This will give you access to the Twilio Console, where you can manage your phone numbers, configure your account, and access the API.

Retrieve Your Account Sid and Auth Token

In the Twilio Console, navigate to the Account section and retrieve your Account Sid and Auth Token. You’ll need these to authenticate your API requests.

Account Sid: ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Auth Token: your_auth_token

Step 2: Install the Twilio Python SDK

Using your preferred package manager (pip in this example), install the Twilio Python SDK:

pip install twilio

Step 3: Authenticate with the Twilio API

In your Python script, import the Twilio SDK and authenticate using your Account Sid and Auth Token:

from twilio.rest import Client

account_sid = 'ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
auth_token = 'your_auth_token'
client = Client(account_sid, auth_token)

Step 4: Upload the Recorded Call to Twilio

Use the Twilio SDK to upload the recorded call to Twilio. Make sure to specify the correct file format (WAV or MP3) and the phone number associated with the call:

call_sid = 'CAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
recording_sid = client.recordings \
                   .create(
                       recording_source='call',
                       recording_source_sid=call_sid,
                       filename='my_recording.wav',
                       content_type='audio/wav'
                   )
print(recording_sid.sid)

Step 5: Transcribe the Recorded Call

Now, use the Twilio SDK to transcribe the uploaded recording. You can specify the language and formatting options:

transcription = client.transcriptions \
                   .create(
                       recording_sid=recording_sid.sid,
                       language_code='en-US',
                       transcribe=True
                   )
print(transcription.sid)

Step 6: Retrieve the Transcription

After the transcription is complete, retrieve the transcription text using the Twilio SDK:

transcription = client.transcriptions(transcription.sid).fetch()
print(transcription.transcription_text)

Formatting Options

You can customize the transcription output by specifying formatting options, such as:

transcription = client.transcriptions \
                   .create(
                       recording_sid=recording_sid.sid,
                       language_code='en-US',
                       transcribe=True,
                       format='combined',
                       verbosity='verbose',
                       smart_formatting=True
                   )

Formatting Option	Description
format	Specify the output format (combined, json, srt, or vtt)
verbosity	Control the level of detail in the transcription (verbose, standard, or default)
smart_formatting	Enable or disable smart formatting (true or false)

Putting it All Together

Here’s the complete Python script to transcribe a recorded dialed call using Twilio:

from twilio.rest import Client

account_sid = 'ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
auth_token = 'your_auth_token'
client = Client(account_sid, auth_token)

call_sid = 'CAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
recording_sid = client.recordings \
                   .create(
                       recording_source='call',
                       recording_source_sid=call_sid,
                       filename='my_recording.wav',
                       content_type='audio/wav'
                   )

transcription = client.transcriptions \
                   .create(
                       recording_sid=recording_sid.sid,
                       language_code='en-US',
                       transcribe=True
                   )

transcription = client.transcriptions(transcription.sid).fetch()
print(transcription.transcription_text)
