The Space at IndexTeam/IndexTTS-2.5-Demo now runs 2.5, but the Demos
column only pointed at the demo page and the ModelScope studio. Add a
Space badge next to them in all five badge-style READMEs, and a plain
[HF Space] link in README2.5_ZH.md, which uses plain links instead.
The recipe has landed, so the links no longer need to reference the pull
request. Verified https://recipes.vllm.ai/IndexTeam/IndexTTS-2.5 returns 200
and titles itself "IndexTeam/IndexTTS-2.5 | vLLM Recipes".
Seven occurrences across the English, Chinese, Japanese, Spanish and Arabic
READMEs.

The 2.5 row's only Demos entry was index-tts2-5.github.io, which serves the
technical report rather than something you can talk to. Add the hosted studio
next to it so a reader can try the model without installing anything.

* fix: repair Linux installs and README commands that fail on a clean machine
Verified on a Linux GPU box using a fresh .venv and a separate UV_CACHE_DIR,
since a warm cache hides every one of these.
pyproject.toml:
- triton-windows had no platform marker, so `uv sync --extra accel` (or
--all-extras) aborted on Linux: the package only publishes win_amd64 wheels.
Linux already gets `triton` as a torch dependency.
- Replace `no-build-isolation-package` with `extra-build-dependencies`. That
mode uses `.venv` itself as the build environment, and a fresh `.venv` has no
setuptools yet, so deepspeed failed with `ModuleNotFoundError: No module
named 'setuptools'` on any clean machine. Injecting torch with
`match-runtime` keeps the CUDA-enabled build inputs while leaving isolation
(and its setuptools) in place. It also lets flash-attn resolve a prebuilt
wheel from its own torch version and C++ ABI flag instead of invoking nvcc.
README (and the zh/ja/es/ar translations):
- `examples/09.wav` does not exist in the demo space and is not in
cases.jsonl; the on-demand download fetches `voice_09.wav`.
- `huggingface-hub` dropped its `cli` extra, so the install line warned.
- Example audio is fetched by the WebUI only, not by `infer_v2_5.py`, whose
default --prompt_wav is `examples/voice_01.wav`. Say so and give a one-liner
to fetch it.
- Drop `uv run indextts/infer_v2.py`: it is a benchmark loop hardcoded to
`checkpoints/`, so with the documented `checkpoints_2` layout it dies on
`vocab_file checkpoints/bpe.model does not exist`.
- `use_emo_text=True` needs `use_qwen_emo=True` at construction, which the
init example omits.
webui.py: title and arXiv badge were hardcoded to IndexTTS2, so the 2.5 UI
announced itself as 2 and linked the 2.0 paper.
* docs: install huggingface-hub without extras
`hf-xet` is an unconditional base dependency of huggingface-hub on x86_64,
arm64 and aarch64, not just an extra, so `[hf_xet]` selected nothing that the
plain package does not already pull in. The plain install still provides the
`hf`, `huggingface-cli` and `tiny-agents` executables.
Applies to the remaining seven translations and archived READMEs too, which
still carried the `[cli,hf_xet]` form whose `cli` extra no longer exists.

* feat: default webui to IndexTTS-2.5
- webui.py: --version default 2 -> 2.5. The v2 default existed only
because the empty-checkpoints auto-download fallback was implemented
for v2 alone; 2.5 just exited. Now both versions auto-download their
own repo (IndexTTS-2 / IndexTTS-2.5) when checkpoints are incomplete.
- webui.py: version-aware required_files. v2 checks bpe.model etc.;
2.5 checks codec.pth + multilingual_zh_ja_yue_char_del.tiktoken
(bpe.model is v2-only, 2.5 uses tiktoken).
- model_download.py: ensure_config_available takes version, downloads
config.yaml from the matching repo instead of hardcoded IndexTTS-2.
- README: 2.5 launch is now 'uv run webui.py' (zero flags).
* Fix ensure_config_available version validation and sync localized READMEs

- Add translated READMEs: docs/README_ja.md, docs/README_es.md,
docs/README_ar.md (structure, code blocks and tables kept identical
to the English README)
- Add WebUI locales: ja_JP.json, es_ES.json, ar_SA.json (110 keys
each, covering every i18n key used in webui.py)
- Fill 3 missing keys in en_US.json (删除/情感向量/语言)
- Add language switcher links to the README headers
Co-authored-by: nanaoto <10inspiral@gmail.com>
- Add light/dark transparent logo variants, switch via <picture>
prefers-color-scheme so the header no longer shows a white box in
GitHub dark mode
- Add stars / arXiv / Discord badges under the language links
- Reorganize both READMEs into a clear section order: header intro,
model zoo, news, demos, getting started, usage, evaluation,
community, citation, acknowledgements, license
- Fix BibTeX author separators (use 'and') and complete the 2.5
author list in the zh README
- Add missing duration_factor and vLLM sections to the zh README
- Drop git-lfs steps (examples download on demand from HF/ModelScope)
- Remove uv advocacy block
Applies the 2.5 work from the internal tree (git.bilibili.co) onto current
main, which already carries the TensorRT backend from #733. The two histories
share no commits, so this is a file-level port rather than a merge.
New:
- indextts/infer_v2_5.py, indextts/gpt/model_v2_5.py
- indextts/codec/ (EnhancedCodec, amphion quantizers, vocos, maskgct codec)
- indextts/utils/tokenizer.py (multilingual), nemo_tn.py, ja_g2p.py
- configs/config_v2_5.yaml
- tests/regression_test.py, tests/cases.jsonl
- archive/README_INDEXTTS_2{,_ZH}.md (2.0 READMEs, superseded by 2.5 at root)
Changed:
- webui.py: --version {2,2.5} switch, language dropdown and duration_factor
slider for 2.5, build_tts() branching on use_bf16 + use_qwen_emo for 2.5 vs
use_fp16 for 2.0
- model_v2.py: spk_cond_mode ("conformer" default keeps 2.0 behaviour,
"campplus" for 2.5)
- infer_v2.py: use_qwen_emo flag so QwenEmotion can be skipped at load
- checkpoint.py: strict=False with missing/unexpected key reporting, needed by
2.5 checkpoints
- pyproject.toml: fugashi, unidic-lite (Japanese g2p), openai-whisper
Deliberately not carried over from the internal tree: its Tencent PyPI and
SJTU torch mirrors, .python-version 3.10 (main pins 3.11.13 per #720), the
.gitignore entry for .github (that tree is on GitLab), and examples/*.wav
(gitignored here and fetched on demand by examples_downloader.py). uv.lock
regenerated with `uv lock` rather than copied.
Verified on 1x RTX 4090: both paths load and synthesize from the merged tree --
2.5 (checkpoints_25) RTF 0.4946, 2.0 (checkpoints) RTF 0.4642, output audio
non-silent in both cases.
The Xet storage method uses de-duplication and chunked downloads to speed up transfers in some situations:
https://pypi.org/project/hf-xet/
But most importantly, installing the Xet support gets rid of some annoying HuggingFace CLI messages about missing the feature.
