model = whisper_s2t.load_model(
    model_identifier="large-v3",
    compute_type="float32",
    device="cuda",
)

result = model.transcribe_with_vad(
    ["audio.wav"],
    lang_codes=["en"],
    tasks=["transcribe"],
    initial_prompts=[None],
    batch_size=1,  # increase this to significantly improve throughput
)

for segment in result[0]:
    print(segment["text"])
```
