Whisper ASR Box is a general-purpose speech recognition toolkit. Whisper Models are trained on a large dataset of diverse audio and is also a multitask model that can perform multilingual speech recognition as well as speech translation and language identification.

Current release (v1.9.1) supports following whisper models:

• openai/whisper@v20250625
• SYSTRAN/faster-whisper@v1.1.1
• whisperX@v3.4.2

docker run -d -p 9000:9000 \
 -e ASR_MODEL=base \
 -e ASR_ENGINE=openai_whisper \
 onerahmet/openai-whisper-asr-webservice:latest

docker run -d --gpus all -p 9000:9000 \
 -e ASR_MODEL=base \
 -e ASR_ENGINE=openai_whisper \

To reduce container startup time by avoiding repeated downloads, you can persist the cache directory:

docker run -d -p 9000:9000 \
 -v $PWD/cache:/root/.cache/ \
 onerahmet/openai-whisper-asr-webservice:latest
