Overview

Our Mock Call & Voice Coaching Agent delivers real-time, interactive, and voice-activated roleplay scenarios to train your sales and support teams. By simulating difficult client objections, onboarding inquiries, and executive pitches, it assesses speech cadence, active listening compliance, and key product triggers.

Interactive Training Focus

Cold Call Roleplay

Simulates tough gatekeeper objections, pricing resistance, and executive decision-maker brush-offs for sales onboarding.

Customer Support Escalations

Roleplays upset clients or severe service outages to audit active listening metrics and tone mitigation skills.

Executive Pitch Audits

Provides a sounding board for sales teams or executives prepping for high-value client presentations, grading message flow.

Key Features

Sub-500ms Audio Streaming

Uses advanced WebRTC codecs to enable completely organic, latency-free vocal exchanges.

Cadence & Sentiment Scoring

Algorithmic speech parsing maps word velocity, sentiment indicators, and silent gap occurrences.

Automated Competency Dashboards

Pushes a complete voice audit score (e.g. Objections Handled, Product Core Met) straight to management directories.

Custom Accent & Tone Selection

Supports dozens of high-fidelity synthetic voices to roleplay global client demographics.

How It Works

  1. Team members launch the voice agent inside their browser or phone.
  2. The voice agent starts a mock conversation (e.g., "Hi, I'm the IT director at Acme, why are you calling?").
  3. Member responds naturally, and the WebRTC system streams speech with low latency.
  4. Generates an objective text transcript and vocal performance scorecard for training reviews.
