Synthesize speech with query string

Speaks the text in the file-script-text query parameter and returns the audio without storing it, for players that can only fetch a URL. It works like POST /domains/{domain}/users/{user}/voices, which suits long text better, since URLs have length limits. Any user can synthesize speech for itself, and Office Manager, Site Manager, Call Center Supervisor, Route Manager, Reseller, and Super User for any user in the domain. Text to speech must be enabled for the user in the path.

audio/wav

The spoken audio, audio/wav (8 kHz, 8-bit, mono), named tts_<hash>.wav in Content-Disposition. The same words in the same voice for the same user are rendered once and served from cache afterward. Each new text is a call to the voice service, billed to the owner in the path: that user, or the domain for a domain-owned path. There is no usage cap beyond the platform's general request rate limit. The body is binary and cannot be shown.
