Performance Metrics

Silero VAD Performance Metrics

All speed test were run on AMD Ryzen Threadripper 3960X using only 1 thread and batch size equal to 1, 16000 sampling rate:

torch.set_num_threads(1) # JIT
session.intra_op_num_threads = 1 # ONNX
session.inter_op_num_threads = 1 # ONNX

RTS - seconds of audio processed per second, real time speed, or inverse RTF

Single chunk (31.25 ms) processing speed, μs	RTS	Model
830	36	V4 JIT
207	151	V4 ONNX
325	96	V5 JIT
189	165	V5 ONNX

This represents the most common use case, but with batch size > 1 metrics can be even more impressive.
