| Data handling | The manual says voiceprints are stored internally on the server, and speaker deletion permanently removes that speaker’s information. | The maker says customers control data location and retention, and audio can be processed in memory or stored using their own storage. |
| Deployment | Authenti is offered in managed cloud and private cloud or on-premise deployment models, including air-gapped deployment. | The API runs fully on-premise or in a private cloud, with audio kept inside the customer's network. |
| Integrations | Authenti is described as integrating into applications, contact centers, voicebots, and enterprise workflows through APIs and SDKs. | The on-premise setup page says calls can connect over SIP, live streaming or the API, with installation via Docker, Kubernetes or bare metal. |
| Purpose | The API provides speaker verification as a RESTful web service using enrollment and later voice comparison. | The SDK and API provide a single interface for deepfake detection, voice biometrics and speech intelligence, running on the customer’s infrastructure. |
| Security | The Authenti page states that API requests are authenticated, data in transit is encrypted, and stored data is encrypted according to deployment configuration. | Spiron says on-premise deployments make zero external calls, and audio and metadata stay within the customer’s network. |
| Support | GoVivace’s contact page lists a support email address and a US office at 1775 Tysons Blvd, Tysons, Virginia 22102. | Customers can request API access and a sandbox key, with contact handled through [email protected]. |
In their own words
GoVivace Speaker Verification API
GoVivace Speaker Verification API enrolls a speaker’s voice and compares later speech with the resulting voiceprint. The manual recommends repeated samples totaling at least 60 seconds for enrollment. Developers can use REST requests or a WebSocket API, with a Python client example; the documented audio example uses 16-bit linear PCM at 8 kHz. API actions include enrolling, searching, deleting, disabling, and enabling speakers. Search can return closest enrolled matches with a chosen count and score threshold. Voiceprints are stored on the server, and deleting a speaker permanently removes that information. GoVivace generates API keys for authentication. Its developer materials describe encryption in transit, configurable encryption at rest, access controls, and audit logging. Authenti deployment options include managed cloud and private cloud or on-premise, with US, India sovereign, and EU-localized hosting choices. Audio and voiceprint retention can be configured per deployment. Pricing is on request; platforms are API and self-hosted.
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.
