Speaker Intelligence Platform

Your audio never leaves your infrastructure.

Speaker diarization with privacy built into the architecture, not bolted on. SaaS when you want speed. Hybrid when you need control.

Hybrid Architecture

SaaS Control Plane

Configuration, billing, model updates. No access to your audio.

Self-Hosted Data Plane

Runs on your infrastructure. Audio processed locally. Never transmitted.

End-to-end encrypted. You control the keys.
Security

How Formantic Protects Your Data

Self-Hosted Data Plane

Audio is processed on your infrastructure. It never touches our servers.

SaaS Control Plane

Configuration, billing, and model updates. No access to your audio data.

End-to-End Encryption

In-transit and at-rest encryption. You control the keys.

Platform

What You Can Build

State-of-the-art speaker intelligence. Language agnostic. Production ready.

Speaker Diarization

Identify who spoke when with state-of-the-art accuracy. Works with any number of speakers, any language.

Speaker Identification

Match voices against known profiles. Track speakers across recordings with persistent voiceprints.

Overlapping Speech

Detect and separate overlapping speakers. Handle interruptions, back-channeling, and crosstalk.

Voice Activity Detection

Detect speech vs. silence with precision. Catches subtle vocalizations like 'mm-hmm' and 'yeah'.

Confidence Scoring

Every segment includes a confidence score. Build human-in-the-loop workflows for low-confidence regions.

YouTube Ingestion

Diarize any YouTube video by URL. Audio is downloaded, normalized, and processed through the full pipeline automatically.
