Decision notes
Official-document research
Based on the cited documentation. We did not use the product, purchase a plan, or run quality, speed or reliability tests in this review.
Consider it for
- Developers adding a local VAD stage
Choose another approach if
- Complete transcripts or identity/language classification
- Unvalidated all-device latency requirements
Pricing and conditions
Documented terms
The published software license permits use without a license fee; this is self-managed software, not a hosted subscription or included API credits. CPU/GPU, memory, downloads, storage, electricity, engineering and any cloud services cost separately. No vendor per-minute bill was established; currency, tax and regional costs depend on the hardware/cloud/provider you choose.

Pricing or terms sourceCode, model and service licensing
The repository presents Silero VAD under MIT, permitting commercial use and redistribution with copyright/permission notices and no warranty. Its README states no telemetry, keys, registration or expiry for this component. That does not license every Silero STT/TTS product or certify the privacy of dependencies, wrappers or your storage. Obtain recording and downstream-use permissions separately; speech detection does not clear rights or consent.
Basis and limits of the recorded score
Original 4.6/5 retained; original scoring worksheet and hands-on evidence were unavailable. This documentation update does not validate the score.
Overview
This listing covers the silero-vad repository, not all Silero speech products. It detects speech regions for segmentation before transcription, voice interfaces or data preparation; it does not itself transcribe words, identify a speaker or determine spoken language. The repository supports 8/16 kHz audio and PyTorch/ONNX paths. ONNX deployment needs supported runtimes and your own input/output and post-processing. Choose thresholds and validate missed speech and false detections against your recordings rather than assuming universal real-time accuracy.

Pros / Cons
Pros
- Downloadable detector and deployment examples
- No built-in registration or key required by the repository
Cons
- Not transcription or speaker identification
- Thresholds, runtime and audio I/O need integration
Who it's for
ASR speech pre-segmentation
Voice-interface input gating
Speech/non-speech dataset preparation
Bottom line
Use it as a configurable speech-detection component and evaluate its thresholds in your full audio pipeline.
