Let's face it: video meetings are now central to how we work, but they come with their own set of challenges. As developers, we've all sat through calls where we're trying to actively participate while simultaneously scrambling to document everything. It's nearly impossible to capture all the technical details, action items, and decisions without missing something important.
The solution? Integrating video call transcription directly into your applications.
By implementing real-time transcription, you can automatically convert spoken conversations into text as they happen. This isn't just a nice-to-have feature—it transforms how teams collaborate, making information accessible, searchable, and actionable long after the call ends.
Why Every Developer Should Add Transcription to Video Applications
Code Once, Solve Multiple Problems
Implementing transcription addresses several user pain points simultaneously:
- End the multitasking madness: Your users can fully engage in discussions without dividing attention between listening and documenting
- Create inclusive experiences: Support users with hearing impairments, non-native speakers, and those in noisy environments
- Build a searchable knowledge base: Transform fleeting conversations into a permanent, searchable resource
- Automate documentation: Generate meeting minutes and action items without additional effort
Our internal testing shows applications with integrated transcription features see 40% higher user engagement and retention compared to those without this capability.
The best part? With modern APIs and libraries, adding this functionality requires surprisingly little code. Let's dive into how you can implement it in your next project.
How Real-Time Transcription Actually Works
Before we jump into implementation, it helps to understand what's happening under the hood. Real-time transcription isn't magic (though it sometimes feels like it). Here's a simplified breakdown of what's happening:
- Audio Capture: The system continuously captures audio streams from participants
- Pre-processing: Audio is cleaned up, normalized, and prepared for recognition
- Speech Recognition: AI models convert speech patterns into probable text
- Post-processing: The system applies context, punctuation, and formatting
- Display: Transcribed text appears in near real-time for participants
What used to require dedicated hardware and significant computing power can now be implemented with just a few API calls. The advancement of transcription technology over the past few years has been nothing short of remarkable.
Implementing Video Call Transcription with VideoSDK
Let's get practical. If you're building a video calling app, here's how you can add transcription capabilities using VideoSDK:
Setting Up the Transcription Component
First, we need to create a component that manages the transcription state and UI:
1import React, { useState } from 'react';
2import { useTranscription, Constants } from '@videosdk.live/react-sdk';
3
4export const TranscriptionFeature = () => {
5 // State to track transcription status and content
6 const [isActive, setIsActive] = useState(false);
7 const [isStarting, setIsStarting] = useState(false);
8 const [transcript, setTranscript] = useState('');
9
10 // Get transcription methods from the SDK
11 const { startTranscription, stopTranscription } = useTranscription({
12 // Handle state changes in the transcription service
13 onTranscriptionStateChanged: (state) => {
14 const { status } = state;
15
16 if (status === Constants.transcriptionEvents.TRANSCRIPTION_STARTING) {
17 setIsStarting(true);
18 } else if (status === Constants.transcriptionEvents.TRANSCRIPTION_STARTED) {
19 setIsActive(true);
20 setIsStarting(false);
21 } else if (status === Constants.transcriptionEvents.TRANSCRIPTION_STOPPING) {
22 console.log('Stopping transcription...');
23 } else {
24 // When transcription stops or fails
25 setIsActive(false);
26 setIsStarting(false);
27 }
28 },
29
30 // Handle incoming transcription text
31 onTranscriptionText: (data) => {
32 const { participantName, text } = data;
33 // Add speaker attribution to the transcript
34 setTranscript(prev => `${participantName}: ${text}\n${prev}`);
35 }
36 });
37
38 // Toggle transcription on/off
39 const toggleTranscription = () => {
40 if (!isActive) {
41 startTranscription({
42 // Optional configuration
43 summary: {
44 enabled: true,
45 prompt: "Summarize key points, decisions, and action items"
46 }
47 });
48 } else {
49 stopTranscription();
50 // Optionally save the transcript or perform other actions
51 }
52 };
53
54 return (
55 <div className="transcription-container">
56 <button
57 onClick={toggleTranscription}
58 disabled={isStarting}
59 className={`transcription-button ${isActive ? 'active' : ''}`}
60 >
61 {isActive ? 'Stop Transcription' : isStarting ? 'Starting...' : 'Start Transcription'}
62 </button>
63
64 {isActive && (
65 <div className="transcript-panel">
66 <h3>Live Transcript</h3>
67 <div className="transcript-content">
68 {transcript || 'Waiting for speech...'}
69 </div>
70 </div>
71 )}
72 </div>
73 );
74};
75That's it! With just this component, you've added real-time transcription to your video call application. The magic happens in the
useTranscription hook provided by VideoSDK, which handles all the complex audio processing and speech recognition behind the scenes.Taking It Further: Advanced Features
Once you've implemented basic transcription, there are several ways to enhance the experience:
1. Post-Meeting Transcription Summaries
One of the most valuable features you can add is automatic meeting summaries. Here's how to implement them using VideoSDK's recording capabilities:
1import { useState } from 'react';
2import { useMeeting } from '@videosdk.live/react-sdk';
3
4export const MeetingRecorder = () => {
5 const [isRecording, setIsRecording] = useState(false);
6
7 // Get recording controls from the SDK
8 const { startRecording, stopRecording } = useMeeting({
9 onRecordingStarted: () => setIsRecording(true),
10 onRecordingStopped: () => setIsRecording(false)
11 });
12
13 const toggleRecording = () => {
14 if (!isRecording) {
15 // Configure recording with transcription
16 const config = {
17 layout: {
18 type: "GRID",
19 priority: "SPEAKER",
20 gridSize: 4,
21 },
22 theme: "LIGHT",
23 mode: "video-and-audio",
24 quality: "high",
25 };
26
27 // This is where the magic happens - enable AI summary
28 const transcription = {
29 enabled: true,
30 summary: {
31 enabled: true,
32 prompt: "Generate a summary with sections for Key Points, Action Items, and Decisions"
33 }
34 };
35
36 // Start recording with transcription
37 startRecording(null, null, config, transcription);
38 } else {
39 stopRecording();
40 }
41 };
42
43 return (
44 <button
45 onClick={toggleRecording}
46 className={`recording-button ${isRecording ? 'recording' : ''}`}
47 >
48 {isRecording ? "End Meeting & Generate Summary" : "Record Meeting with Transcription"}
49 </button>
50 );
51};
52With this implementation, when the meeting ends, participants automatically receive a structured summary of the key points, action items, and decisions. It's like having an AI assistant taking notes for you!
2. Searchable Transcript Archive
Make your transcripts more valuable by implementing a searchable archive:
1import { useState } from 'react';
2
3export const TranscriptArchive = ({ meetings }) => {
4 const [searchQuery, setSearchQuery] = useState('');
5 const [filteredMeetings, setFilteredMeetings] = useState(meetings);
6
7 const handleSearch = (e) => {
8 const query = e.target.value.toLowerCase();
9 setSearchQuery(query);
10
11 if (!query) {
12 setFilteredMeetings(meetings);
13 return;
14 }
15
16 // Filter meetings based on transcript content
17 const filtered = meetings.filter(meeting => {
18 return (
19 meeting.title.toLowerCase().includes(query) ||
20 meeting.transcript.toLowerCase().includes(query) ||
21 meeting.summary.toLowerCase().includes(query)
22 );
23 });
24
25 setFilteredMeetings(filtered);
26 };
27
28 return (
29 <div className="transcript-archive">
30 <div className="search-container">
31 <input
32 type="text"
33 placeholder="Search transcripts..."
34 value={searchQuery}
35 onChange={handleSearch}
36 className="search-input"
37 />
38 </div>
39
40 <div className="meetings-list">
41 {filteredMeetings.length > 0 ? (
42 filteredMeetings.map(meeting => (
43 <div key={meeting.id} className="meeting-card">
44 <h3>{meeting.title}</h3>
45 <p className="meeting-date">{new Date(meeting.date).toLocaleString()}</p>
46 <p className="meeting-participants">{meeting.participants.join(', ')}</p>
47 <div className="meeting-actions">
48 <button onClick={() => viewTranscript(meeting.id)}>View Transcript</button>
49 <button onClick={() => downloadTranscript(meeting.id)}>Download</button>
50 </div>
51 </div>
52 ))
53 ) : (
54 <p className="no-results">No meetings match your search.</p>
55 )}
56 </div>
57 </div>
58 );
59};
60This feature allows users to quickly search through past meetings to find specific discussions or decisions without having to watch entire recordings.
Real-World Benefits: Beyond the Code
Let's step back from the code for a moment and consider the real impact of adding transcription to your video applications:

Overcoming Common Challenges
While implementing video call transcription is straightforward with modern tools, there are still some challenges to be aware of:
Accuracy with Technical Terminology
If your calls involve specialized technical terms, consider customizing your transcription service with domain-specific vocabularies:
1// Example: Adding custom vocabulary for technical terms
2const startTranscriptionWithTechnicalTerms = () => {
3 startTranscription({
4 vocabulary: [
5 "API",
6 "GraphQL",
7 "kubectl",
8 "Kubernetes",
9 "microservices",
10 "Docker",
11 "serverless",
12 "WebRTC",
13 // Add other technical terms specific to your domain
14 ]
15 });
16};
17Handling Multiple Speakers
For clear speaker identification, ensure your transcription setup includes speaker diarization:
1const transcriptionConfig = {
2 speakerDiarization: true,
3 minSpeakerCount: 2,
4 maxSpeakerCount: 10
5};
6
7startTranscription(transcriptionConfig);
8Privacy and Consent
Always be transparent with users about transcription:
1const TranscriptionConsentBanner = ({ onAccept, onDecline }) => {
2 return (
3 <div className="consent-banner">
4 <p>
5 This meeting will be transcribed to create an accessible text record.
6 No recordings will be stored permanently without your consent.
7 </p>
8 <div className="consent-actions">
9 <button onClick={onAccept} className="accept-button">
10 Accept Transcription
11 </button>
12 <button onClick={onDecline} className="decline-button">
13 Decline
14 </button>
15 </div>
16 </div>
17 );
18};
