Thank you for reaching out! The warning

livekit.plugins.silero - inference is slower than realtime

means that the Silero Voice Activity Detection (VAD) model is taking a bit longer to process the audio than the actual length of the audio itself, which can cause a delay in real-time performance. This usually happens when processing a small segment of audio (around 32ms) takes more than 200 milliseconds. Over time, these delays add up, and that's when the warning pops up. Some common reasons for this include: • Your CPU might be busy with other tasks or might not be powerful enough. • The model might be a bit too complex for your system's processing capabilities. Here are a couple of things you might try to help improve the situation: • Make sure your system has enough CPU resources available. • Try prewarming the VAD model to help reduce the startup time. I hope this helps! If you have any more questions or need further assistance, please feel free to ask.
