The main difference between real-time and batch speech transcription lies in when and how the audio is processed.
- Transcription en temps réel converts speech to text instantly as it’s spoken, ideal for live meetings or broadcasts.
- Batch transcription, on the other hand, processes pre-recorded audio or video files in bulk, making it perfect for post-production, documentation, or research purposes.
Let’s explore their differences in detail and see which one best fits your workflow.
🕐 What Is Real-Time Speech Transcription?
En temps réel speech transcription captures spoken words and converts them into text immediately. This process relies on low-latency AI models that process audio streams continuously, providing live captions or subtitles.
🔸 Key Features:
- Instant text output while someone is speaking
- Continuous updates as speech progresses
- Requires stable internet and high-quality audio input
🔸 Common Use Cases:
- Live webinars and online meetings
- TV broadcasting and live events
- Customer service chatbots and AI assistants
Real-time transcription focuses on speed and interactivity, not necessarily perfection, since accuracy may fluctuate with accents, noise, or poor microphones.
📦 What Is Batch Speech Transcription?
Batch transcription — sometimes called asynchronous transcription — processes recorded media files after the fact. Instead of instant output, the system analyzes the full file before returning the text, often resulting in higher accuracy.
🔸 Key Features:
- Ideal for large-scale or long-form recordings
- Higher accuracy through complete context analysis
- Supports background noise reduction and punctuation
Batch transcription is especially useful for research teams, media archives, and content creators who need to convert long recordings efficiently.
⚙️ Key Differences: Real-Time vs Batch Transcription
| Fonctionnalité | Real-Time | Batch |
|---|---|---|
| Vitesse | Instantané | Slower (depends on file size) |
| Précision | Moderate (affected by noise) | Higher (context-aware) |
| Évolutivité | Limited to live sessions | Can handle thousands of files |
| Cas d'utilisation | Meetings, events | Post-processing, analytics |
| Internet Requirement | Always-on | Can be offline or cloud-based |
If you’re handling live calls or need captions during events, real-time is best. But for processing large archives or podcasts, transcription par lots is far more efficient.
