Prepaid TTS credits vs subscriptions: why Audra bills packs — Audra

Unit economics matter once you leave trial volume — here is how Audra prices against list rates. Not for realtime voice agents or cloning.

Who this is for

Finance and eng reviewing TTS unit economics at 500k–10M chars/month
Teams comparing prepaid Audra packs vs seat-taxed voice platforms
Builders who care about QA-gated refunds on failed renders
Anyone modeling spend before a migration decision

Pricing focus: prepaid model

Audra Essential prepaid is $25/1M characters (volume tiers down to $12). Plus, Pro, and Conversations apply fixed multipliers on that base — full table on /pricing#engines.

ElevenLabs-style list rates (~$120/1M) dominate at 2M+ chars/month for batch-only work
OpenAI tts-1 (~$15/1M) wins raw $/char without mastering or large sync limits
Audra bills QA-gated — failed renders auto-refund (see /blog/tts-api-billing-qa-gated)
First $5 pack is 50% off with WELCOME20 after the 25k free trial

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.
