OpenAI Whisper Large V3 Turbo | Multilingual Speech-To-Text API

OpenAI Whisper Turbo

OpenAI Whisper Turbo is a fast, accurate speech-to-text transcription model powered by OpenAI's Whisper architecture. It converts audio into clean, readable text with support for multiple languages — ideal for transcription, subtitling, and voice-driven workflows.

Why It Stands Out

High-speed transcription: Optimized for fast processing without sacrificing accuracy.
Multilingual support: Transcribe audio in dozens of languages with automatic language detection.
Prompt-guided transcription: Steer output formatting, terminology, or punctuation with custom prompts.
Prompt Enhancer: Built-in AI-powered prompt optimization for better transcription guidance.
Flexible input: Supports direct audio upload or public URL.

Parameters

Parameter	Required	Description
audio	Yes	Upload or link to an audio file (MP3 / WAV / M4A, etc.).
language	No	Language code for transcription; leave empty for auto-detection.
prompt	No	Short guidance text to steer transcription style or terminology.
enable_sync_mode	No	Wait for result before returning response (API only).

How to Use

Upload your audio — drag and drop a file or paste a public URL.
Select language (optional) — choose a specific language or let the model auto-detect.
Add a prompt (optional) — guide formatting, punctuation, or specific terminology.
Click Run and wait for transcription to complete.
Copy or download the transcribed text.

Best Use Cases

Meeting Transcription — Convert recorded meetings, interviews, and calls into searchable text.
Subtitle Generation — Create accurate transcripts for video subtitling workflows.
Content Repurposing — Turn podcasts, webinars, and lectures into written content.
Voice Notes — Quickly transcribe voice memos and audio notes.
Accessibility — Generate transcripts to make audio content accessible.

Pricing

Metric	Price
Per second of audio	$0.0007 / s

Total cost = duration of audio (in seconds) × $0.0007

Examples

60s audio → 60 × $0.0007 = $0.042
5 min (300s) audio → 300 × $0.0007 = $0.21
30 min (1800s) audio → 1800 × $0.0007 = $1.26

Pro Tips for Best Quality

Use clear audio with minimal background noise for optimal accuracy.
Specify the language if auto-detection is inconsistent.
Add a prompt to guide transcription — include names, jargon, or formatting preferences.
For long recordings, consider splitting into smaller segments for faster processing.

Notes

Ensure uploaded audio URLs are publicly accessible.
Processing time varies based on audio duration and current queue load.
