Cobalt VoiceBio provides voice biometrics for verifying or identifying speakers, including when operation is independent of spoken text. It converts speech into voiceprints that represent a speaker’s voice rather than what they said. StreamingVerify compares live audio with one voiceprint and returns a similarity score and match decision. StreamingIdentify checks live audio against a list of voiceprints and returns the best match or none. StreamingEnroll creates voiceprints and indicates how much more audio is needed to finish enrollment. Voiceprints can also be compared without resending audio or vectorized for indexing and downstream tasks. The engine runs on customer hardware, keeping audio and voiceprints inside the customer’s infrastructure. Cobalt lists embedded, on-premise, and private cloud deployment options. The product serves a gRPC API, with pre-generated Go and Python SDKs and instructions for generating others. The trial supports 8 kHz and 16 kHz speech, lasts 100 days, and is free; Arm64 is excluded. Listed requirements are an x86_64 CPU, 500 MB disk space, and 2 GB RAM. Pricing is otherwise on request.
