Introduction
Transforming audio recordings from meetings into searchable, shareable text is revolutionary in the fast-paced business world of today. You can easily automate the laborious and error-prone process of manual transcription with Google's Speech-to-Text API and Salesforce. This guide, which includes code samples and best practices, takes you step-by-step through the process of putting up an end-to-end solution for creating transcripts directly within Salesforce.
Why Automate Transcripts?
- Save Time: Instantly convert audio to text instead of manual note-taking.
- Improve Accuracy: Leverage Google’s advanced AI for precise transcriptions.
- Centralize Data: Store transcripts alongside Salesforce records for easy access.
Prerequisites
- A Salesforce org with Custom Settings enabled.
- A Google Cloud account with the Speech-to-Text API activated.
- Basic familiarity with Apex and Salesforce configuration.
Step 1: Configure Google Speech-to-Text API
-
Enable the API in Google Cloud:
- Navigate to the Google Cloud Console.
- Enable the Speech-to-Text API under APIs & Services.
-
Generate an API Key:
- Go to Credentials > Create Credentials > API Key.
- Copy the key—it will be stored securely in Salesforce later.
Step 2: Set Up Custom Settings in Salesforce
Store your Google API key and endpoint URL securely using Salesforce Custom Settings:
-
Add URL to Remote
- Got to Setup, then Remote Site Setting
- Create New Remote site
Remote Site Name: Google API
Remote Site URL: https://speech.googleapis.com
-
Create a Custom Setting named API_Setting__c with two text fields:
- Google_API_Key__c
(value: YOUR-AIP-KEY) - Google_speech_to_text_URL__c
(value: https://speech.googleapis.com/v1/speech:recognize)
- Google_API_Key__c
- Insert a record with your API key and URL.
Step 3: Upload Audio Files to Salesforce
Follow the user manual steps to:
- Create an Account
- Upload a .wav audio file (under 1 minute) via the Files related list.
Step 4: Integrate Google’s API Using Apex
The Apex class handles the integration. Here’s a breakdown of key components:
1. Fetching and Encoding the Audio File
The getBase64EncodedFile method retrieves the latest version of the uploaded file and encodes it to Base64:
2. Calling Google’s API
The transcribeAudio method constructs the API request with language and encoding settings:
3. Parsing the Response
The extractTranscript method processes Google’s JSON response and concatenates the transcript:
4. Store the Transcription
Store the generated transcript
Error Handling & Best Practices
- Security: Use with sharing in the Apex class to enforce user permissions.
- Validation: Check audio file size and format before upload.
- Error Logging: The try-catch blocks ensure exceptions are logged in Salesforce debug logs.
- Rate Limits: Google’s API has quotas—monitor usage in the Cloud Console.
