08/13/2025, 7:54 PMinference is slower than realtime
means the Silero VAD plugin is taking a bit longer to process than expected, which might cause some delay. No worries though, here are some friendly tips to help you speed things up:
1. Optimize VAD Configuration:
◦ Try setting force_cpu
to True
when initializing VAD if you don’t have a GPU handy—this helps keep CPU inference steady.
◦ Play around with settings like max_buffered_speech
to shrink the buffer size and lighten the processing load.
1. Boost Your System Resources:
◦ Make sure you have enough CPU cores available, and think about turning on multi-threading for ONNX sessions to spread the work.
◦ If your CPU isn’t working hard enough, tweaking inter-op threads might give it a little nudge.
1. Try Some Alternatives:
◦ Pre-warming the VAD model before you start processing audio can really help speed things along.
◦ Also, keep an eye out for plugin updates—they often come with performance boosts!
Give these a shot, and you should see less delay and smoother performance from the plugin. If you need a hand with any of this, just let me know—I’m here to help!
