Verdicts
Deepgram Text-to-Speech (Aura-2, Flux TTS)
OpenAPI 3.1 and AsyncAPI files, llms.txt and Markdown pages. Requests can be kept for training unless each one sets mip_opt_out=true.
PlayHT Text-to-Speech API
The old API reference is still readable at docs.play.ht for anyone porting code. api.play.ht doesn't resolve, so every call fails.
Before you call either
Deepgram Text-to-Speech (Aura-2, Flux TTS)
- Set
mip_opt_out=trueon every request if the text mustn't be kept for training. - Split Aura-2 REST text under 2,000 characters or expect a 413.
- Pass
modelon/v2/speak, where it's required. - Strip SSML before sending, since it's removed with an
INPUT_MARKUP_STRIPPEDwarning. - Back off exponentially on 429 and keep traffic in one project.
PlayHT Text-to-Speech API
- Don't call api.play.ht, it doesn't resolve.
- Ignore docs.play.ht code samples, they describe a closed service.
- Map PlayDialog or Play 3.0 Mini work to another TTS listing before writing code.
