Direct Answer (TL;DR)
The Brilo AI voice agent detects long pauses as silence (voice activity detection) and follows your configured patience timeout and voicemail or callback rules. You can change patience level, enable advanced noise cancellation (noise suppression), and set voicemail or auto callback behavior so the AI business phone system can either prompt the caller, leave a message, schedule a callback, or escalate to a human when silence persists.
Why This Question Comes Up (problem context)
Contact centers lose context when callers pause for many reasons. Slow or non-native speakers, intermittent connectivity, and noisy environments can all look like silence. Leaders want predictable call flows so Brilo AI voice agent capabilities do not hang up too soon or wait forever. Teams also want to avoid false silence triggers that degrade automatic speech recognition (ASR) accuracy.
How It Works (High-Level)
The Brilo AI voice agent uses audio controls and call-handling rules to decide what to do during a pause. Voice activity detection (VAD) marks when the caller is silent. The Brilo AI voice agent evaluates ASR confidence (transcript confidence) and signal-to-noise ratio (SNR) to decide whether to ask for repetition, wait longer, or follow a fallback. The patience setting controls the silence timeout. When the patience timeout is reached the Brilo AI voice agent follows the configured voicemail behavior or callback workflow.
Guardrails & Boundaries
Guardrails set safe behavior for the Brilo AI voice agent. Typical guardrails include confidence-based escalation thresholds that prevent the Brilo AI voice agent from guessing when ASR confidence is low. Guardrails also include restricted-topic lists and explicit stop conditions where the Brilo AI voice agent must transfer the call. You should configure how many “Are you still there?” prompts the self-learning AI agent may use and whether the Brilo AI voice agent records a voicemail or schedules an outbound callback before ending the call.
Applied Examples
For slow or non-native speakers the Brilo AI voice agent can use a higher patience timeout and one follow-up prompt before taking voicemail.
For missed-answer scenarios the Brilo AI voice agent can leave a pre-recorded voicemail message after silence is detected.
For callback requests the Brilo AI voice agent can capture details and create an auto callback entry in the scheduling queue when auto callback (outbound scheduling) is enabled.
For noisy lines the Brilo AI voice agent can rely on advanced noise handling to reduce false silence triggers while keeping patience moderate.
Human Handoff & Escalation
When rules require a human, the Brilo AI voice agent transfers according to your escalation path. The AI business phone system can include a short call summary that lists the intent, key fields captured, and why the handoff occurred. Escalation can trigger immediate warm transfer or create a ticket for a callback. Use ASR confidence thresholds and explicit caller requests to force a human handoff in the Brilo AI voice agent workflow.
Setup Requirements
To configure silence handling for an AI business phone system, you typically provide the following items and settings:
Admin access to the Brilo AI portal and the target voice avatar.
Desired patience levels and patience timeout values for the Brilo AI voice agent.
Voicemail behavior text or recorded message the Brilo AI voice agent will play.
Auto callback routing rules and who will execute outbound callbacks.
Advanced noise cancellation settings in the agent’s audio configuration.
Escalation recipients and human transfer rules.
A small test plan and sample calls to validate VAD, ASR confidence, and SNR behavior.
Business Outcomes
Tuning silence handling for the Brilo AI voice agent reduces abandoned calls and improves first contact resolution. Better noise suppression and proper patience settings increase ASR transcript quality for analytics. Predictable voicemail and auto callback behavior lowers repeat contacts and improves customer experience by ensuring callers get the right follow-up or a smooth handoff to humans.
