SALT Software is Now Part of Cobalt
SALT Software is the leading platform for language sample analysis, helping speech-language pathologists collect, analyze, and interpret spoken language for assessment, treatment planning, progress monitoring, and research.
The SALT team has joined Cobalt. Together, we're continuing to develop new technologies that advance language assessment while supporting clinicians, researchers, universities, and healthcare organizations.
- Language sample analysis
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.
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.
Privacy Built-In
Keep sensitive audio, transcripts and voice data within the infrastructure your organization chooses.
Built to adapt
Customize acoustic and language models for specialized vocabulary, accents, acoustic environments, devices and workflows.
Flexible deployment
Embedded on a device, on-premise, in a private cloud, or as batch or streaming services.
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.
Speech Recognition & Transcription
Turn spoken language into accurate, usable text with models adapted to specialized environments and terminology.

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

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.
What partners say about working with Cobalt.
“Cobalt Speech and Language is the perfect partner for a small business like ours to tackle the challenges of speech recognition. We have very much enjoyed working together.”
“We have been working with the Cobalt team on advanced methods of using the Vocalzoom HMC sensor for improving performance of existing speech recognition systems and for user authentication. Their extensive knowledge and capabilities allow us to innovate around the unique features of our sensor.”
“As an AI-powered solution in search of a speech application, Cobalt's ability to provide agile, custom speech solutions that scale on demand sets them apart from others in the market.”
“Jeff Adams and his team have contributed immensely to the success of FluentWorlds. They are both brilliant technologists and incredibly responsive. Our company would not be where it is today but for the outstanding contributions of the Cobalt team.”
