 ## Benchmark and Technical Report
 
-Stay tuned for a technical report comparing WhisperS2T against other whisper pipelines. Meanwhile, check some quick benchmarks on A30 GPU.

+**NOTE:** For first run the model may give slightly slower inference speed. After 1-2 runs it will give better inference speed. This is due to the JIT tracing of the VAD model.
