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
Configuration, billing, model updates. No access to your audio.
Runs on your infrastructure. Audio processed locally. Never transmitted.
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.
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.
