Spatius + Silero Voice Activity Detection

Silero VAD can be evaluated with Spatius through the documented turn detection boundary described below. Use the linked first-party references as the implementation source of truth.

Integration boundary

What connects to what

Silero controls user turn boundaries in the cascade; approved assistant TTS begins a Spatius turn, while interruption cancels the current visual and audio response.

Silero VADaudio / session boundarySpatius Motion Servermotion + synchronized audioAvatarKit client rendering

Prerequisites

  • Current Silero VAD credentials and access
  • Spatius App ID, Avatar ID, and an approved session-token flow
  • A defined audio source, format, sample rate, and interruption policy
  • A test environment that matches the target browser, device, or server runtime

Implementation path

Build a testable baseline

  1. 1

    Confirm the current Silero VAD version and read both linked first-party sources.

  2. 2

    Run the smallest official Spatius sample without the partner dependency to establish an avatar baseline.

  3. 3

    Connect Silero VAD at the audio or session boundary described in the architecture section.

  4. 4

    Verify audio format, pacing, interruption, reconnect, cleanup, and credential isolation.

  5. 5

    Record versions, target devices, network conditions, failures, and rollback behavior before production.

Decision guidance

Best for and not best for

Best for

  • Teams already committed to Silero VAD
  • Developers who want to keep the avatar layer separable from the conversation stack

Not best for

  • Teams requiring an unverified integration to be treated as production-ready
  • Buyers looking for a fully managed end-to-end avatar-video service

Evidence-aware assessment

Advantages and limitations

Advantages

  • Adds a Silero VAD-specific implementation decision instead of a generic provider list
  • Keeps the Spatius rendering boundary explicit
  • Provides a concrete validation and failure checklist

Limitations

  • Aggressive thresholds can create repeated false interruptions. Silero is a dependency in a reference pipeline, not a feature embedded inside the Spatius SDK.
  • Current package and API versions still require release-time verification
  • No first-party benchmark for this exact combined stack is included in the supplied evidence
Validation disclosure

Aggressive thresholds can create repeated false interruptions. Silero is a dependency in a reference pipeline, not a feature embedded inside the Spatius SDK. Indexing this guide does not convert an architecture blueprint into a claimed native connector; run and document the validation checklist before production use.

Page-specific FAQ

Implementation questions

Is Silero VAD a native Spatius connector?

The supplied evidence classifies this as a documented path. Recheck the linked first-party sources for the current support boundary.

What must be tested before production?

Credentials, audio access and format, sample rate, interruption, reconnect, backpressure, cleanup, privacy, versions, and target-device behavior.

Does this page include performance results?

No. It does not publish latency, FPS, bandwidth, or reliability numbers for this exact combined stack without a reproducible first-party test.
