Self-host ONNX TTS vs Audra API: ops cost honesty — Audra
Honest comparisons beat feature checklists when the workload is batch narration. Not for realtime voice agents or cloning.
Who this is for
- Teams evaluating Audra against an incumbent TTS vendor
- Engineers who need an honest cloning vs batch-narration split
- Buyers who want OpenAI-compatible migration paths
- Anyone comparing samples before changing production endpoints
Comparison focus: self-host tradeoff
Audra is batch narration with OpenAI-compatible HTTP — not a clone of realtime agents or voice cloning stacks. Stay on the incumbent when cloning or sub-200ms agents are core product value; switch when $/char at volume, mastered MP3, and QA refunds matter more.
- Migration path is baseURL + model id — /migrate usually takes minutes
- Side-by-side samples live on /compare
- Methodology and live usage notes on /proof
- Deep dives: /vs/elevenlabs and /vs/openai-tts

FAQ
Is Audra OpenAI-compatible?
Yes. Point the OpenAI SDK at https://audratalks.com/v1 with model audra-essential — copy-paste on /migrate.
What does QA-gated billing mean?
Credits finalize only after automated QA passes. Failed renders refund automatically.
Does Audra support realtime voice agents?
No. Audra is a batch TTS API for mastered MP3/WAV files. For sub-200ms conversational agents, stay on a realtime-oriented provider.
Can I clone a custom brand voice?
No. Audra ships preset voices only. Use ElevenLabs (or similar) when cloning is a hard requirement — see /vs/elevenlabs.
