AI audio platform for speech, agents, music and dubbing
Generate expressive speech across 90+ languages with multiple model options tuned for latency, consistency or emotional range.
Create instant voice clones on starter plans and professional clones on higher tiers, or design voices from a text prompt.
Configure, test and monitor agents that handle voice and chat conversations across phone, messaging and support channels.
Translate and dub video and audio into other languages, with automatic and studio workflows plus watermark options.

One AI API key for text, image, video, and code models
Call many different models through one base URL and one API key, so existing OpenAI-style clients and SDKs usually need only minor changes.
Access text and reasoning models alongside image, video, and audio/music generation endpoints from the same integration.
Route routine traffic through a value tier to reduce spend, and move critical workloads to an official tier when stability matters more than cost.
Manage credentials and usage in one place instead of juggling separate accounts, quotas, and invoices across vendors.
