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.

Checked against comfy_api_nodes/nodes_heygen.py (HeyGenVoiceCloneNode, HeyGenVoiceTextToSpeechNode). Defaults and ranges match: similarity default max, remove_background_noise on, seed 42, first 180 s used, text 1 to 5000, expressiveness_boost 0 to 1 default 0.5, turbo at half price. Template, preview and long_demo.mp3 URLs return 200.

A few points:

  1. Two statements in Limits are not in the node source, which only sends model, voice_id, text, expressiveness_boost and language: "Plain prose only; anything else is rejected" and "Instant voices ignore seed, speed, and pitch". If they come from HeyGen's API docs, please link that source. Otherwise I'd drop them, since the node exposes no speed/pitch anyway.
  2. docs.json: the new HeyGen group is appended after Sonilo in the audio section, while the other provider groups there are alphabetical. Consider moving it before Sonilo (same in zh/ja/ko).
  3. Minor: the clone node's seed is not sent to HeyGen. It only forces a re-run, which creates a new clone. The current wording ("change seed to clone again") is fine.

docs.json conflicted because upstream regenerated and re-indented it (Comfy-Org#2067,
Comfy-Org#2068). Took upstream's version and re-added the HeyGen nav group in the four
language blocks, right after the Sonilo group.

code-pages:check is fresh, check-anchors passes on the four pages, and the
structure matches across languages.

The template is live in Comfy Cloud, so restore the cloud card in all four
locales and sync the translation hashes.

- **Clone from a short recording**: 10 seconds of clear speech is enough, and up to 3 minutes of the clip is used
- **Reuse the voice**: the `voice_id` output plugs into text to speech, or into `custom_voice_id` on HeyGen Avatar Video and HeyGen Talking Photo
- **Two speeds**: `heygen-voice-1-turbo` is faster and costs half as much as `heygen-voice-1`

Correct the Turbo price comparison.

The Text to Speech node’s price badge lists Turbo below half the standard model’s per-character rate in both rate periods. Replace “costs half as much” with a comparison that matches the declared rates, or say only that Turbo costs less. Update the same claim in the Korean, Japanese, and Chinese pages.

3. **Write the script**: on **HeyGen Voice 1.0 Text to Speech**, enter up to 5000 characters of plain prose in `text`, and connect the `voice_id` output of the clone node to its `voice_id` input
4. **Set the delivery**: `expressiveness_boost` from 0 to 1. `0` stays closest to the recording, `1` adds the most emotion
5. **Click Queue** or press `Ctrl+Enter` to generate
6. **Save the result**: the template writes the audio with **SaveAudioAdvanced** and the voice ID with **SaveText**, under `output/HeyGen_Voice_id/`

Give separate output paths for audio and the voice ID.

The linked template saves audio with the audio/heygen_voice_1 prefix. Only SaveText uses HeyGen_Voice_id/. If readers look for both outputs under output/HeyGen_Voice_id/, they will not find the audio there. Correct Step 6 in all four locales. (raw.githubusercontent.com)
