Verdicts

PlayHT Voice Cloning API

The API reference is still readable at docs.play.ht, useful for mapping old integrations. Shut down, api.play.ht doesn't resolve.

Speechify API Voice Cloning

Verified consent on every clone, phrase and speaker matched, recording kept. No cloning on the Free plan.

Before you call either

PlayHT Voice Cloning API

  1. Don't call api.play.ht. The host doesn't resolve
  2. Ignore docs.play.ht for new work. It documents an API that no longer exists
  3. Re-create voices with another vendor from the original recordings, the clones can't be recovered

Speechify API Voice Cloning

  1. Create the consent challenge only when the speaker is ready. It's single use and short-lived
  2. Show the phrase as returned. Rewording it fails the match
  3. Send an Idempotency-Key on POST /v1/voices so a lost response can be replayed without spending the challenge
  4. Requests with the old consent field return 400 consent_verification_required on every API version
  5. On 429 wait for Retry-After, then check error.code to tell a rate limit from a concurrency cap
