Direct Answer (TL;DR)
Brilo AI voice agent handles multiple speakers (crosstalk) by using audio pre-processing and configured call-handling rules to prefer the dominant speaker, ask for clarification, or follow a fallback such as voicemail or transfer. The best capabilities of an AI phone call agent include overlapping speech handling (overlap recognition), configurable noise cancellation (noise suppression), and optional escalation via warm transfer so human agents receive context when needed.
Why This Question Comes Up (problem context)
Platform administrators and ops teams see degraded transcripts, missed details, or poor summaries after calls where customers, agents, and third parties speak at the same time. Teams ask how the Brilo AI voice agent decides who is speaking, whether transcripts will show speaker labels (speaker diarization), and what fallback behavior the Brilo AI voice agent will take when audio is unclear.
How It Works (High-Level)
During an inbound call, the Brilo AI voice agent first applies audio pre-processing such as noise cancellation (noise suppression) and voice activity detection (VAD). The Brilo AI voice agent then uses automatic speech recognition (ASR) to transcribe the dominant speaker. If the AI phone call agent detects sustained overlap, the configured call flow determines the best next step. Call distribution features include asking the caller to repeat, routing to voicemail, or performing a warm transfer to a human agent with the captured context.
Guardrails & Boundaries
Brilo AI voice agent guardrails prevent unsafe or unreliable behavior when crosstalk is present. Typical guardrails include confidence thresholds in ASR, escalation rules that trigger when diarization (speaker diarization) or transcription confidence falls below a set level, and restricted-topic rules to avoid automated decisions on sensitive issues. The Brilo AI voice agent should not invent facts when audio is ambiguous. If the Brilo AI voice agent cannot confirm required details, the configured fallback must be executed.
Applied Examples
A support inbound agent: The Brilo AI voice agent captures the dominant speaker during brief interruptions, prompts for clarification when overlap is long, and uses voicemail as a fallback if audio remains unreadable.
A sales qualification flow: The Brilo AI voice agent collects company and timeline details from the caller. If a third party joins and overlap degrades transcription confidence, the AI phone call agent triggers a warm transfer so the best human rep receives the lead with context.
A three-way conference: The Brilo AI voice agent focuses on the person with the highest signal-to-noise ratio after noise suppression. If speaker-separated transcripts (speaker labels) are required, the Brilo AI voice agent operator must confirm diarization availability on the account before relying on speaker-attributed notes.
Human Handoff & Escalation
Human handoff is part of Brilo AI voice agent call handling features. When warm transfer is configured, the Brilo AI voice agent packages a short summary and the information collected so the receiving human does not ask for basic details again. Escalation rules can be confidence based. The Brilo AI voice agent can also escalate on demand when the caller asks for a person. Test warm-transfer flows to confirm context preservation in your telephony topology.
Setup Requirements
To configure Brilo AI voice agent behavior for multiple speakers, provide these items:
Call goals and acceptable fallback actions for unclear audio, such as ask to repeat, voicemail, or warm transfer.
Approved prompts and clarification scripts for overlap detection.
Transfer targets and routing rules for warm transfers.
Audio settings to enable advanced noise handling and voice activity detection (VAD).
Test phone numbers and a staged conference setup with two or more human participants for validation.
Sample recordings and times when behavior should differ so Support can reproduce problems.
Business Outcomes
When the Brilo AI voice agent handles crosstalk correctly, organizations see better first-contact resolution and fewer repeated questions. Improved audio pre-processing raises ASR confidence which improves transcript quality and analytics. Properly configured warm transfers reduce caller friction and lower handle time for human agents because context is preserved. Clear fallback rules reduce the risk of incorrect automated actions during overlapping speech.
Next Step
Validate your phone call agent by running the best staged conference tests and adjusting audio and fallback settings in the Brilo AI Console.
