# NVIDIA TTS

> NVIDIA provides enterprise-grade neural text-to-speech via the NVCF API.

## Overview

NVIDIA delivers text-to-speech through the NVIDIA Cloud Functions (NVCF) API, serving neural voice synthesis from NVIDIA's high-throughput inference infrastructure. It is well-suited for enterprise deployments requiring scalable, low-latency TTS.

## Authentication
