Ranked in AI Voice Biometrics Software ·Free trial
About
Cobalt VoiceBio provides voice biometrics for verifying or identifying speakers, including when operation does not depend on the words spoken. It turns speech into voiceprints that represent a speaker's voice. StreamingVerify compares live audio against one voiceprint and returns a similarity score and match decision; StreamingIdentify checks live audio against a list and returns the best match or none. StreamingEnroll creates voiceprints and indicates how much more audio is needed to finish enrollment. Voiceprints can be compared without resending audio or vectorized for indexing and downstream tasks. The engine runs on customer hardware, keeping audio and voiceprints inside that infrastructure. Deployment options include embedded, on-premise, and private cloud. VoiceBio provides a gRPC API and pre-generated Go and Python SDKs, with instructions for generating SDKs in other languages. Its 100-day trial costs 0.00 USD per free, supports 8 kHz and 16 kHz speech, and excludes Arm64. Listed requirements are an x86_64 CPU, 500 MB disk space, and 2 GB RAM.
Who it is for
It suits organizations that need speaker verification or identification and want the engine to run inside their own infrastructure. The listed use cases include authenticating customers, employees, and partners, with passcodes or other credentials as possible companions.
