HeyGen Voice 1.0 adds two partner nodes, an instant voice clone and a Voice 1.0 text to speech node (Comfy-Org/ComfyUI#17043, HeyGenVoiceCloneNode and HeyGenVoiceTextToSpeechNode in comfy_api_nodes/nodes_heygen.py), and the matching api_heygen_voice_1 template shipped in Comfy-Org/workflow_templates#1364.

This adds a tutorial page for the workflow and lists it under the partner-node audio navigation in all four languages.

Facts taken from source:

  • Instant Clone: one speaker recording, first 3 minutes used, similarity options medium / high / extra_high / max (default), remove_background_noise on by default, seed re-clones
  • Text to Speech: models heygen-voice-1 and heygen-voice-1-turbo, text 1 to 5000 characters, language auto or explicit, expressiveness_boost 0.0 to 1.0 (default 0.5)
  • the template is local-only (includeOnDistributions: ["local"]), so the Cloud card stays commented out until it is available in Comfy Cloud

Preview templates/api_heygen_voice_1-1.webp and input input/long_demo.mp3 both verified 200. The cloning and per-1K-character rates are in #2027.

Add a tutorial page covering the instant voice clone and Voice 1.0 text to
speech nodes, list it under the partner-node audio navigation for all four
languages, and keep the rates in the pricing PR.
