Platform Overview

Welcome to Volo, a real-time audio accessibility platform designed for live and hybrid events. This overview explains the major components of the system, the roles involved, and how content flows from a presenter’s microphone to an attendee’s device.

What Volo Delivers

• Live transcription so attendees can read along in their preferred language.
• AI-driven translation that mirrors the spoken program in near real time.
• Text-to-speech playback for audiences who need audio reinforcement in another language.
• Presenter-friendly tooling that keeps event producers in control without extra hardware.

Core Components

1. Admin Console (Event Producer UI)
   Web application used to create events, configure rooms, and initiate audio ingest.

2. Real-Time Processing Pipeline
   Managed cloud services that receive audio, run speech-to-text and translation models, and distribute text/audio streams to attendees.

3. End User Experience
   Mobile-first web app that provides language selection, live captions, and optional text-to-speech playback.

User Roles at a Glance

Role	Responsibilities	Related Doc
Event Producer	Configure events, start/stop audio ingest, manage room assets	/roles/event-producer/
End User	Join a room, choose a language, follow along	/roles/end-user/
A/V Partner	Supply a clean audio feed and maintain signal integrity	/audio-ingest/ and internal playbooks

Workflow Snapshot

1. Prepare the event
   Event Producer creates the event and rooms, uploads branding, and prints the QR code.

2. Connect audio
   The onsite A/V team feeds a balanced audio signal into a USB interface connected to the Event Producer’s laptop. See Audio Ingest for best practices.

3. Start streaming
   In the Admin Console, the Event Producer selects the input device, verifies levels, and presses Start to stream.

4. Consume content
   Attendees scan the room QR code, select a language, and receive live captions or translated audio on their phones.

5. Monitor and iterate
   Producers watch room health indicators, confirm audience feedback, and stop the stream when the session ends.

Technical Requirements

• Browser support: Latest Chrome or Safari for producers; modern mobile browsers for attendees.
• Audio hardware: Class-compliant USB interface, XLR cables, and reliable power.
• Network: Stable uplink of 5 Mbps or greater with low jitter.
• Security: OTP login for producers; session-scoped URLs for attendees.

Key Considerations

Plan for accessibility

Reserve time before doors open to test audio ingest, confirm language availability, and verify that QR codes lead to the correct room.

• Redundancy: Keep spare cables, a second USB interface, and a backup laptop when possible.
• Noise floor: Monitor for hum or clipping and adjust gain at the source.
• Privacy: Obtain consent when required; mute the ingest when confidential content begins.

Where to Go Next

• Review the Audio Ingest guide for hardware setup tips.
• Walk through the Event Producer role guide to practice starting a stream.
• Share the End User guide with onsite support staff.
• Capture outstanding questions in the FAQ so the team can document answers.
