What we know about Orpheus TTS
Orpheus TTS sits in the text-to-speech apis category, where it is the 'LLM-as-TTS' approach under Apache-2.0 - expressive and clonable, but repo activity has slowed since mid-2025. We keep this Orpheus TTS profile grounded in primary sources, each fact dated to when we last confirmed it.
Orpheus TTS does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Orpheus TTS quote, it is the fastest way for us to close that gap.
On capabilities, Orpheus TTS covers streaming audio output, instant voice cloning, emotion / style controls, and self-host / on-prem option. Each of those is verified against Orpheus TTS's own docs or dashboard, not marketing copy.

STT in this stack
Text-to-speech is half of a voice pipeline: the other half is the speech-to-text that listens. Compare transcription engines on accuracy, streaming latency, and per-minute price: Deepgram, AssemblyAI, GPT-4o Transcribe, or the full speech-to-text comparison →
Voice agents in this stack
The engine is one layer: a voice agent speaks through its text-to-speech engine, but orchestration, telephony, and turn-taking come from the agent platform. Compare the platforms builders pair Orpheus TTS with: Pipecat, OpenAI Realtime API, Twilio ConversationRelay, or the full voice-agent comparison →

Most Orpheus TTS voiceover ends up in short-form video, and publishing that video across TikTok, YouTube, and Instagram is a scheduling problem with real per-channel pricing. Compare the schedulers creators actually run: Buffer, Postiz, Mixpost, or the social media scheduling platforms compared →
Avatar video in this stack
A cloned or bring-your-own Orpheus TTS voice does not have to stay audio-only: AI avatar video platforms lip-sync it onto a talking avatar for finished video. Compare the platforms: HeyGen, Synthesia, Hedra, or the full avatar-video comparison →
