Spiron Voice Biometrics API provides a single interface 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 APIs support real-time bidirectional streaming, JSON responses, and webhooks for asynchronous pipelines, with official SDK clients for Python, Go, and Java. Deployments can run on-premise, in air-gapped, private cloud, or hybrid environments. Spiron says customers control data location and retention, and that audio can be processed in memory or kept in their own storage. On-premise deployments make no external calls, keeping audio and metadata within the customer’s network. Results include confidence scores and evidence trails. Runtime options include Linux servers, GPU acceleration with CPU fallback, and horizontal scaling. Pricing is available on request. API access and a sandbox key can be requested, and a free online demo is listed without installation or a credit card.
Who it is for
Spiron is aimed at banks, critical infrastructure, and government environments handling sensitive voice data, as well as contact centers and media workflows. It may suit teams that need voice analysis deployed within their own infrastructure.
