Nvoice

Nvoice is a cloud-based voice technology platform that provides automatic speech recognition (ASR), text-to-speech synthesis (TTS), and voice analytics for developers and enterprises. It offers APIs and SDKs to build conversational interfaces, accessibility tools, and voice-enabled workflows across customer service, education, media, and automotive sectors.

Originating as a product line within a speech-processing company, Nvoice was introduced to the market in the mid-2010s. The platform has since added neural TTS with natural prosody, real-time streaming ASR, and multilingual support.

Core features include real-time streaming, low-latency inference, and customizable voices. The system supports voice biometrics for authentication, noise-robust recognition, and deployment options that include cloud, on-device, or hybrid configurations.

Nvoice is designed as an API-first architecture built on microservices. It provides REST and gRPC interfaces, streaming via WebSocket, and tooling for model fine-tuning, analytics, and monitoring.

Use cases include contact centers, accessibility tools for the visually impaired, automotive infotainment, smart homes, and media transcription. The platform is recognized for language coverage and security features, though users consider pricing and vendor dependency in procurement decisions.
