One platform alerts, responds, accounts and proves, on an always-on voice engine.

Alert, guide, and account for everyone.

Named for Martyn Hett, who lost his life in the Manchester Arena attack in 2017, Martyn’s Law, formally the Terrorism (Protection of Premises) Act, puts a legal duty on public venues to notify, guide and account for every person when it matters.

Enforced by a new Security Industry Authority (SIA) function, procedures must be documented, drilled and demonstrable. whoot. supports those obligations in one platform: always-on voice for your team, and two-way SMS that reaches everyone else on any phone.

Standard tier, 200+ capacity

reasonably practicable procedures to reduce harm and enable evacuation

Enhanced tier, 800+ capacity

risk assessments, security plans, staff training, cooperation with authorities

Designated senior individual

a named person accountable for compliance

Documented and demonstrable

procedures recorded, drilled and evidenced on inspection

Notify and guide

Always-on voice rooms keep your security team connected at all times, and one tap sends two-way SMS to everyone else: no app, no data connection, just their normal Messages inbox. Push-to-talk reaches every member instantly · two-way SMS to any phone · zone-specific rooms for targeted alerts.

Full accountability

A designated senior individual needs an evidence base. whoot. records every communication, decision and action with an immutable, exportable trail for SIA inspection. Immutable audit logs: who, what, when · speaker identification on all recordings · exportable reports for inspections.

Documented procedures

Procedures must be recorded and demonstrable, not just written down. Real-time AI transcription turns every drill and incident into searchable, attributable text. Speech-to-text in 30+ languages · AI summaries and action items · full-text search across every record.

Drill and improve

The Act expects staff training and continuous improvement. Scenario replay turns every drill into a training asset and every incident into a lesson. Timeline scrubbing with speaker waveforms · synced transcript: click a line, jump to audio · identify response gaps and refine.

whoot. for Martyn’s Law

Reach everyone, even without the app.

Martyn’s Law is about the public, and most of the public is not in a voice room. One tap sends an SMS alert to every phone on your list: no app, no data connection, just their normal Messages inbox, where texts get read fast.

And it goes both ways. A one-way blast only tells you what you said; a reply tells you who is safe, who needs help and who is already at the assembly point, every response threaded right beside your voice channels.

Reaches any phone

No app, no data connection, just their Messages inbox.

It talks back

Replies thread back into whoot., beside your voice.

Know who is safe

Acknowledgements tracked live: who is safe, who is stuck.

One list, both ways

Send and receive on one number and one list.

SMS pricing

See the incident, not just hear it.

When an incident is declared, whoot. turns live voice into a real-time intelligence picture. AI extracts entities, tracks threats, analyses vocal stress and corroborates independent reports, as your teams speak, in under eight seconds.

Radio logs tell you what happened. Intelligence tells you what is happening, so operators command the response instead of piecing together radio traffic by hand. Every word spoken during an active incident runs through a multi-stage pipeline: extraction, corroboration, sentiment and pattern analysis.

Stress analytics

WPM

AI entity extraction

The AI engine analyses every utterance in real time. Threat actors, weapons, hazards, casualties, locations and requests are extracted automatically; no manual tagging.

Vocal stress analysis

Speaking rate (WPM) from word-level timestamps combined with AI sentiment. Detect stress spikes, panic and escalation before they are reported.

Threat actor tracking

Deduplicated threat actors with corroboration scoring. Independent reports about the same suspect are merged automatically via semantic embeddings.

Corroboration engine

1536-dimension semantic vectors group independent reports about the same entity and raise the corroboration score as evidence mounts, separating a rumour from a confirmed fact.

Location intelligence

Every mentioned location mapped with threat or clear status. See which areas are compromised and which are cleared at a glance.

Casualty tracking

Live casualty counts aggregated from field reports. Injury types, tallies and medical-request statuses updated in real time.

Incident replay

Gap-compressed timeline replay with speaker waveforms, transcription sync, entity markers, event annotations and a vocal-stress overlay.

Phrase and pattern analysis

N-gram heatmaps surface recurring phrases and themes across field comms: coordination patterns, repeated threats, escalation language.

After-action review

Auto-assembled incident dossiers, action-item tracking and an exportable after-action report: the evidence base for review and inspection.

The response, staged.

Detect · incident declared

Declare an incident from the dashboard. Intelligence extraction activates automatically and the AI begins processing every utterance.

Coordinate · live intelligence

Field teams report via push-to-talk. Entities, sentiment and locations stream into the dashboard as operators confirm and disseminate.

Analyse · pattern recognition

The corroboration engine links independent reports, phrase heatmaps surface emerging patterns, and stress analytics flag escalation early.

Review · incident replay

Gap-compressed replay of the entire incident: every utterance, entity, event and stress spike, scrubbable, searchable, exportable.

Explore incident response

Rooms that never close.

An incident does not book a meeting. Always open, always ready: the channel already exists when the first report comes in. Push-to-talk keeps crosstalk at zero. Latch mode keeps your hands free. Real-time presence tells you who is listening before you say a word.

• Sub-150ms WebRTC audio with automatic codec negotiation
• Push-to-talk and latch (toggle): your team, your rules
• Real-time presence and live speaking indicators
• In-room text messaging for links, files and quick notes

Voice rooms

Security and complianceSecurity specification

Platform capabilities that round out the day.

Multi-region

Deploy in the region closest to your team. Latency measured in milliseconds.

Emergency alerts

Activate sirens and visual alerts across every connected device. Push notifications bypass user preferences. Configurable duration.

Speaker ID

Every voice identified and labelled, in recordings, transcriptions and live sessions alike.

Data retention

Configurable retention with automatic cleanup for full compliance.

Access reviews

Periodic audits to verify every user, every permission, every room assignment.

Cross-tenant sharing

Share rooms with external organisations. Guest tenants collaborate without leaving their workspace.

Catch-Me-Up

Join mid-conversation and get an instant AI summary. No scrolling, no asking, just context.

Real-time replay

Scrub back through live audio without leaving the room.

Live monitoring

One board reads every room for the duty manager: a live pulse per room, plain-English summaries of what each is saying, and signals when things start lining up, before anyone declares. Wallboard mode for the control room.

Voice log

Say “Control, log…” and the words after it become an entry in the day’s occurrence book, under the speaker’s name, with the recording a click away. Typed entries and corrections keep the original.

Duress phrases

A phrase staff agree in advance that means “I cannot say I’m in trouble”. Hearing it opens a case, reaches every security manager’s phone through Do Not Disturb, and sends nothing back to the speaker.

Occurrence book and evidence pack

The day exported as CSV or a PDF occurrence book with a written handover summary; any incident exported as a sealed evidence pack: timeline, log lines, the audio behind them, photos, and SHA-256 checksums.
