PlayHT

Purpose

Generate spoken audio from text with PlayHT voices, browse stock and cloned voices, and create instant voice clones. Reach for this when the user wants narration or voiceovers, a voice library lookup, or a voice cloned from a sample.

Tooling

All commands go through bin/playht.py. PlayHT uses a single uppercase AUTHORIZATION: Bearer <key> header (older dual-header docs are stale); the CLI wires it through the credential surrogate.

bin/playht.py auth
# {"ok": true, "voices": 120} on success

bin/playht.py voices
# list stock voices (id, name, language, gender)

bin/playht.py tts --text "Welcome to the show." --voice-id <VOICE_ID> --out show.mp3
# streaming synthesis to a local MP3 file; prints the saved path

bin/playht.py clones
# list your cloned voices

bin/playht.py clone --json clone-body.json
# create an instant voice clone; body follows the current PlayHT docs
# for POST /api/v2/cloned-voices/instant/ (confirmation-gated)

Notes:

• tts returns audio binary. The CLI writes it to --out (default playht-output.mp3) and prints the resulting path. Max 20,000 characters per request; PlayHT rate-limits to 120 requests/min per key.
• Batch synthesis jobs are credit-consuming and confirmation-gated; they are not in this draft CLI.

Auth

• Provider id: playht (credential is collected as custom.playht)
• Collection: PlayHT API key via the secure credential flow (credentials.request_api_access); generate one under Settings, then API, in the PlayHT dashboard
• Allowed hosts: api.play.ht
• Connect placement: custom_header:AUTHORIZATION (uppercase; the stored credential value must include the Bearer prefix, since the helper places the header value verbatim: AUTHORIZATION: Bearer <key>)
• Status check: bin/playht.py auth

Operating Rules

1. Synthesis is credit-metered and rate-limited (120 req/min, 20,000 chars/request). Keep tts calls within the character cap; split long scripts before calling.
2. Voice cloning and batch synthesis are confirmation-gated: confirm with the user before running clone or any batch job. Only clone voices the user has the right to clone.
3. Never log or print the raw key; the CLI only ever handles the surrogate.
4. Ignore older PlayHT docs that describe a dual-header scheme (Authorization + X-USER-ID); the current API uses the single uppercase AUTHORIZATION header.

Maturity

🧪 Draft: written from PlayHT's current public docs with paths cross-checked at build time; not yet live-tested end-to-end. TTS jobs (async batch synthesis) are not yet in the CLI.
