PTT & Radio Monitoring

Cortexa is designed specifically for push-to-talk (PTT) and private mobile radio (PMR) environments. These networks are the dominant communication medium in heavy industry, and Cortexa is the only intelligence platform built for their specific characteristics.

What makes industrial radio different

Standard speech recognition fails in industrial radio environments because:

Transmissions are short, fragmented, and often incomplete
Multiple speakers use overlapping callsigns and non-standard identifiers
Heavy background noise — machinery, wind, vehicle engines
Highly compressed audio codecs (AMBE, ACELP) degrade signal quality
Mixed-language crews and strong regional accents
Jargon, abbreviations, and site-specific vocabulary unknown to general models

Cortexa was built for these conditions, not adapted from a general-purpose transcription tool.

How Cortexa connects to radio infrastructure

Cortexa ingests channel audio at the network or device level. No changes are required to existing radios, repeaters, or dispatch consoles. Integration methods include:

Network-level audio feed from TETRA, DMR, P25, or broadband-PTT controllers
Direct audio stream from dispatch recording infrastructure
Device-level audio where network integration is not available

Channel and speaker management

Unlimited channels monitored simultaneously from a single deployment
Channels can be pinned to specific crew groups, languages, or operations
Speaker profiles are built automatically from callsign patterns and transmission history
Channel audio is stored locally with configurable retention policies

Multilingual operation

Cortexa detects the language of each individual transmission automatically. No pre-configuration per channel is required. Supported languages: English, Arabic, Spanish, French, Dutch, German. Mixed-language utterances within a single transmission are handled natively.
