OmniVoice is an open-source AI voice platform that generates natural text-to-speech, clones a voice from a 3–25 second sample with zero training, and creates custom voices from a text description — all through one unified model spanning 646 languages, including hundreds of low-resource languages. It's aimed at content teams and developers producing audiobooks, game dialogue, podcasts, and support voices, with cross-lingual cloning and batch-friendly inference. Its main differentiator is language breadth far beyond ElevenLabs (32) or PlayHT (132), paired with open-source availability and free credit-based access.

Vogent is a platform for building humanlike voice AI agents that can place and handle phone calls, using building blocks like IVR detection and navigation models, low-latency custom voices, and conversational LLMs fine-tuned on millions of phone calls. It offers a no-code drag-and-drop Flow Builder as well as APIs and SDKs for developers, plus call history, outcome extraction, and post-call automations. Users can host agents on live phone numbers and bring their own OpenAI-compatible models.
