Nemotron 3.5 Transcribe is an open-weight 30B-A4B speech-augmented language model from NVIDIA for offline transcription in 40 languages. It handles recordings up to one hour and adds speech translation, contextual and speaker-attributed transcription, word timestamps and audio question answering, leading open-weight models on English, long-form and multilingual ASR.

You can use cURL or any other http client to run inferences:
curl -X POST \
-H "Authorization: bearer $DEEPINFRA_API_KEY" \
-F audio=@my_voice.mp3 \
'https://api.deepinfra.com/v1/inference/nvidia/NVIDIA-Nemotron-3.5-Transcribe-30B-A4B'
which will give you back something similar to:
