The broad except ImportError was swallowing the actual failure reason
(e.g. a missing transitive dep after --no-deps install). Now captures
and re-raises the original exception in the error message so users
can diagnose what is actually missing.

Dynamic JS inputs that are not listed in INPUT_TYPES may be rejected by
ComfyUI's prompt validator and not passed to the Python function. Declaring
all 8 slots as optional fixes this while JS still controls which slots are
visible on the node.

Drop any audio file (wav/flac/mp3/ogg/m4a) into the presets cache dir and
it will appear as "<name> (local)" in the Voice Preset dropdown on next
ComfyUI restart. Add a same-stem .txt file for the transcript.

Each line starting with [Tag] now begins a new segment so users don't need
blank lines between tagged speeches. Continuation lines (no tag) are joined
to the previous tagged segment for multi-line speeches.

- Add OmniVoiceSpeaker node (label + ref_audio + ref_text → OMNIVOICE_SPEAKER)
- Add OmniVoiceSpeakers node (roster with dynamic speaker_N inputs driven by
num_speakers INT widget; slots expand/collapse via ComfyUI JS extension)
- Add web/multi_speaker.js: ComfyUI extension that hooks onNodeCreated and
onConfigure to sync speaker_N inputs in real time (max 8 speakers)
- Extend OmniVoiceGenerate with optional speakers (OMNIVOICE_SPEAKERS) input;
when connected it routes each paragraph to the assigned speaker and
concatenates the results — supports alternate_paragraphs and tagged_speakers modes
- Remove OmniVoiceMultiSpeakerGenerate (generation now lives in the existing
Generate node)
- Refactor generator.py: extract _write_tmp_wav helper, add _tensors_to_audio

Chinese characters vs English words are self-identifying to the model.
No need for a separate language signal on either node.

Voice Design now outputs (instruct, language) — wire language directly
into Generate to avoid setting it in two places. Generate's language
input is now a STRING (accepts the connection or manual 'auto').

pydub, tensorboardx, webdataset are omnivoice dependencies that won't
be present on a clean ComfyUI install since we use --no-deps.

Pinning transformers==5.3.0 risks conflicting with existing ComfyUI venv.
Back to permissive >=4.40.0 which worked in practice.

- Generate: language dropdown (auto/English/Chinese), passed only in
voice_design and auto_voice modes where it selects the instruct vocab
- VoiceDesign: Chinese mode with dialect/age/pitch/gender dropdowns
using the model's validated Chinese instruct vocabulary (全角逗号)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The model's _resolve_instruct() validates against a fixed vocabulary.
Only 10 accents are supported — removed all unsupported additions.
Updated tooltip to reflect actual constraints.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
If instruct is set alongside ref_audio, it is now forwarded to
model.generate() — allowing accent/style transfer on top of the
cloned voice identity. Model may or may not honour both simultaneously.

Language: ~170 world languages with type-to-filter dropdown
Accent: 50+ regional varieties grouped by area
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
OmniVoiceVoiceDesign: structured dropdowns for gender/age/pitch/accent
that compose into an instruct string — wire to Generate's instruct input.
OmniVoiceGenerate: new optional language dropdown (auto + 11 languages)
and guidance_scale (CFG, default 2.0) parameters.

Refreshed node IDs, positions and sizes from live session. Replaced
SaveAudio with PreviewAudio, added ref_text widget entry, updated
aux_id/ver properties.

ComfyUI appends a hidden "fixed"/"randomize" value after every INT
named "seed". Without it the widget values were misaligned.

Compiles the model graph on first generation (~30-60s warmup) then
speeds up all subsequent generations in the session. Recommended for
audiobook pipelines. Default off.

Generate node height 340→400 to fit all 6 widgets, Voice Preset
height 80→100, SaveAudio position adjusted.

Catching bare Exception was silently swallowing real resampling errors.
Only ImportError should trigger the interpolate fallback.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- _resample: squeeze batch dim before torchaudio.Resample (expected 2D)
- weight scaling: each clip now trims to natural_length*weight samples,
dropping the broken target_per_unit double-multiplication
- empty trimmed guard: raise clear error when all weights are 0

Sets a default seed so the voice stays consistent across all generated
chunks when using the workflow as a starting point for audiobook pipelines.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
OmniVoice chunks long text internally; each chunk is a separate diffusion
pass with different random noise, causing voice drift between paragraphs.
Setting the same seed before each generate() call anchors the RNG state
and keeps the voice consistent. seed=0 means random (default behaviour).

get_text(separator=' ') collapsed all paragraphs into one line.
Now inserts \n\n at block-level element boundaries (p, h1-h6, div,
li, br, tr) before extraction, then normalises whitespace.

Models always download to ComfyUI/models/omnivoice/ via HuggingFace.
Local path added unnecessary complexity; users who want a custom path
can symlink into the models directory.

Connect a Whisper node to ref_text for auto-transcription.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Users should connect a ComfyUI Whisper node to ref_text instead of
relying on omnivoice's internal ASR. Removes the error-catch workaround
and updates the tooltip accordingly.

requirements.txt cannot install omnivoice (it would pull in torch==2.8.*
and break ComfyUI). install.py now does exactly one thing: install
omnivoice --no-deps, skipped if already present. All other deps remain
in requirements.txt for ComfyUI Manager to handle normally.
