ElevenLabs alternative: OpenAI-compatible TTS at $25/1M — Audra

ElevenLabs set the bar for expressive TTS — but API list pricing (~$120/1M characters) hurts when your product renders hours of narration every month. Audra targets the same OpenAI-compatible HTTP shape at $25/1M with broadcast loudness and QA-gated billing baked in.

This is not a feature-for-feature clone. Audra optimizes for batch pipelines: course modules, podcast episodes, doc readers, and cron jobs that POST text and store MP3s. If you need voice cloning or sub-200ms realtime agents, stay on ElevenLabs. If you need predictable unit economics, read on.

Price at realistic volumes

• 500k chars/mo — save ~$47 vs ElevenLabs list
• 2M chars/mo — save ~$190/mo
• 10M chars/mo — save ~$950/mo before volume tiers
• Interactive model — use /calc with your last invoice
