    Collect and analyze natural speech and language samples.

  • Clinical assessment tools

    Powerful tools that support accurate assessment and documentation.

  • Research & education

    Advancing language science through research and collaboration.

  • Powered by Cobalt technology

    Built on secure, accurate, and scalable technology.

Why Cobalt

Speech technology without the usual constraints.

Cobalt helps organizations deploy speech and language technology around their actual operating, security, infrastructure and domain requirements, not around a fixed public API.

01

Privacy Built-In

Keep sensitive audio, transcripts and voice data within the infrastructure your organization chooses.

02

Built to adapt

Customize acoustic and language models for specialized vocabulary, accents, acoustic environments, devices and workflows.

03

Flexible deployment

Embedded on a device, on-premise, in a private cloud, or as batch or streaming services.

Products

A complete speech and language technology portfolio.

Three product families cover recognition, intelligence and interaction — with a research group for problems that off-the-shelf models do not address.

Cobalt Labs & Expertise

When an off-the-shelf model isn't enough.

Cobalt adapts or develops speech and language systems for problems that general-purpose models handle poorly. Our team works across acoustic modeling, language modeling, NLU, TTS and speaker biometrics.

  • Domain-specific terminology
  • Noisy acoustic environments
  • Alternate microphone configurations
  • Accented speech
  • Children's speech
  • Dysarthric speech
  • Specialized applications
  • Embedded and edge environments
Selected applications

Where Cobalt technology is used.

Secure transcription for regulated industries

Batch and streaming ASR deployed inside the customer's infrastructure, so audio and transcripts never leave it.

Voice interfaces for self-service

Conversational voice interfaces built with Cobalt Interact for portals, applications and support systems.

Custom voice and biometric technology

Adapted models for speaker verification and identification in devices and applications.

Contact-center speech intelligence

Redaction, diarization and analytics for high-volume call audio.
