Short answer
Yes. For a national insurer, EngineAI, the build team of FirstNet's AI business unit FirstCoreAI, processed 965 call recordings into structured, searchable data on sovereign infrastructure, so no recording left South Africa.
In detail
The pipeline covered every stage from audio to usable data:
- Transcription and correction of every recording.
- Name resolution across calls.
- Structured JSON output for downstream systems.
- Processing entirely on local infrastructure.
Keeping call recordings local matters because sending them to an offshore AI API is a cross-border transfer, with POPIA consent and breach questions attached. The FirstCoreAI AI Factory in FirstNet's South African data centre includes a speech-to-text model exposed through an OpenAI-compatible audio transcriptions endpoint.
Document and call pipelines are a core EngineAI capability, covering intake, extraction, transcription and structured output for large volumes of files and recordings. FirstCoreAI names call archives as a typical use case in financial services and insurance, and as a good single workload to start with.
FirstCoreAI can scope your own archive on a 30-minute scoping call.
