OpenAI Whisper (Large-v3) is a production-ready speech recognition model that transcribes or translates audio into clean, readable text. With support for dozens of languages, optional word-level timestamps, and flexible task modes — it's ideal for subtitling, transcription, and multilingual workflows.
| Parameter | Required | Description |
|---|---|---|
| audio | Yes | Upload or link to an audio file (MP3 / WAV / M4A, etc.). |
| language | No | Language code for transcription; use "auto" for automatic detection. |
| task | No | Choose "transcribe" for same-language or "translate" for English output. |
| enable_timestamps | No | Generate word-level timestamps (may increase processing time). |
| prompt | No | Short guidance text to steer transcription style or terminology. |
| enable_sync_mode | No | Wait for result before returning response (API only). |
| Mode | Price |
|---|---|
| Standard (no timestamps) | $0.001 / s |
| With timestamps enabled | $0.002 / s |
Total cost = duration of audio (in seconds) × price per second
The maximum supported audio duration is 10 minutes. Longer audio is automatically trimmed to 10 minutes before processing.
Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/openai-whisper with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Openai Whisper below.

time.sleep(2)Openai Whisper is a WaveSpeedAI model for AI inference, exposed as a REST API on WaveSpeedAI. Whisper Large v3 speech-to-text: instant, accurate multilingual transcripts with automatic language detection and punctuation. Upload audio to get transcripts. Ready-to-use REST API, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/openai-whisper.
Openai Whisper starts at $0.001 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `audio`, `enable_sync_mode`, `enable_timestamps`, `language`, `task`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/openai-whisper.
Median end-to-end generation time on WaveSpeedAI is around 16 seconds per request, based on recent successful runs. Queue time varies with global demand; live status is visible in the prediction record.
Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
