Orpheus
llm-style emotive tts with streaming, apache-licensed
a llama-based, emotive open model with streaming and emotion tags, apache-2.0 so you can ship it — english-centric, and you'll need a real gpu for real-time.
orpheus, from canopy labs, is a llama-3.2-3b-based tts with eight voices, emotive tags (laugh, sigh and the like), and low-latency streaming, all under apache-2.0 so it's commercial-safe. self-host it or use it on fal.ai at $0.05 per 1k characters. for an expressive, permissively-licensed open model aimed at agents, it's a good pick.
it's english-centric and, being a 3b model, needs a real gpu for real-time use, so its ~200ms streaming figure assumes proper hardware and is a vendor claim. within those bounds it's one of the more expressive open options.
