Verdicts

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.

Resemble AI Text-to-Speech API

OpenAPI file in JSON and YAML, llms.txt and Markdown pages. Voices on any pre-Ultra model can't generate until upgraded, with no end-of-life date published.

Before you call either

PlayHT Text-to-Speech API

  1. Don't call api.play.ht, it doesn't resolve.
  2. Ignore docs.play.ht code samples, they describe a closed service.
  3. Map PlayDialog or Play 3.0 Mini work to another TTS listing before writing code.

Resemble AI Text-to-Speech API

  1. Check the voice's model before synthesis, since voices on pre-Ultra models fail until upgraded.
  2. Keep each synchronous request under 2,000 characters.
  3. Decode audio_content from base64 on /synthesize, or call /stream for raw WAV chunks.
  4. Send Authorization: Bearer, since some doc examples leave out the prefix.
  5. Log the request ID with every failure, since the error body has no code.
