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.

VoiceStudio

Local audio generation with HTTP and MCP access. Hardware and model licences vary by backend.

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

VoiceStudio

  1. Keep the server on loopback unless network authentication has been verified.
  2. Use file outputs for large audio and restrict the output directory.
  3. Check the selected model licence before commercial voice use.
