Voice AI

Venture Twins gave Dreamina a photo, a talking clip, and office images to make an a16z SF walkthrough in their voice and likeness. Replies said the clip was one continuous generation and noted European IP access limits.

Allie Miller described using Codex Voice Mode for trackers, email, reminders, scheduling, and document work. Min Choi’s ElevenLabs setup shows a browser agent that listens, streams replies, and handles interruptions.

A sponsored explainer thread described Speech Engine as a WebSocket layer that adds speech-to-text, turn detection, interruption handling, and text-to-speech to existing LLM agents. The pitch is that teams can keep their current model stack and add voice without rebuilding the whole agent.

Supertone open-sourced Supertonic, a local TTS engine that runs faster than real time on phone CPUs with ONNX models and cross-language runtimes. Voice apps and audiobook workflows can use it to avoid per-character API billing and keep audio generation private.

xAI rolled out Grok Voice Think Fast 1.0 with ready-made tool schemas for medical offices, restaurants, help desks, real estate, appointments, and hotel concierge tasks. The release lowers setup work because common service actions arrive pre-wired as callable tools.

OpenBMB released VoxCPM on GitHub with text-described voice design, 3-second cloning, 48kHz audio, and 30-language support. The Apache 2.0 release makes multilingual voice work and local self-hosting cheaper.
