Spiron Voice Biometrics API
Spiron Voice Biometrics API provides an SDK and API for deepfake detection, voice biometrics, and speech intelligence on customer infrastructure. Voice functions include speaker verification and identification; speech tools include speech-to-text, language identification, emotion analysis, speaker diarization, age and gender analysis, and keyword spotting. REST and gRPC interfaces support real-time bidirectional streaming, JSON responses, and webhooks for asynchronous pipelines. Official SDK clients are listed for Python, Go, and Java. Deployment options include on-premise, air-gapped, private cloud, and hybrid environments. Spiron says customers control data location and retention, and audio may be processed in memory or stored using their own storage. On-premise deployments make no external calls, with audio and metadata kept within the customer network. Responses include confidence scores and evidence trails. The runtime supports Linux servers, GPU acceleration with CPU fallback, and horizontal scaling. Pricing is on request; API access and a sandbox key can be requested, and a free online demo is available.
