# Multi-lingual TTS Data (leeoxiang/multi_lingo_data)

Large-scale cross-lingual + same-lingual TTS corpus for training expressive
multi-lingual voice-clone models. Covers 4 target languages
(**en / ja / ko / zh**), synthesized by `bosonai/higgs-tts-3-4b`
via sglang-omni.

> **🚧 Upload in progress** — the main `samelang_expressive` corpus
> (≈ 4.78 M rows / **≈ 3.3 TB**) is being pushed as parquet shards.
> Expect the shard count to grow over the next hours/days until each
> language reaches `train-XXXXX-of-00240.parquet`.

## 🎧 Listen first — `samples_showcase`

40 randomly-picked cross-lingual sample pairs (10 per target language)
from the `samelang_expressive` corpus, each paired with the *reference
wav* used for voice cloning so you can A/B the timbre. This is what the
HF viewer above shows by default.

```python
from datasets import load_dataset
ds = load_dataset("leeoxiang/multi_lingo_data", "samples_showcase", split="train")
print(ds[0]["text"], ds[0]["audio"]["sampling_rate"])
```

## 📦 Main corpus — `samelang_expressive` (**≈ 4.78 M rows, in progress**)

Same-language expansion: for every pseudo-reference (real Emilia speaker
cross-cloned into the target language via `audio_prompts_expressive`), we
synthesize **1000 target-language texts**, giving
`1200 speakers × 4 langs × 1000 texts ≈ 4.8 M` cloned wavs.

- **Shards**: `data/samelang/<lang>/train-XXXXX-of-00240.parquet`
  (each lang → 240 shards, ≈ 5000 rows/shard)
- **Row schema**: `audio` (struct{bytes, path}, auto-cast to HF `Audio`
  feature) + `text`, `lang`, `ref_id`, `speaker_id`, `text_id`,
  `duration`, `sample_rate`, `ref_audio_path`, `ref_text`, `engine`,
  `original_text`
- **Total size (fully uploaded)**: **≈ 3.3 TB** audio, ≈ 4.78 M rows, ≈ 11 k h
- **Engine**: `sglang-omni-higgs-audio-v3` with expressive relabel-based
  prompt (drawn from the top-quality pool per source speaker)

### Streaming (recommended for 3.3 TB)

```python
from datasets import load_dataset
ds = load_dataset(
    "leeoxiang/multi_lingo_data",
    "samelang_expressive",
    split="train",
    streaming=True,
)
row = next(iter(ds))
print(row["lang"], row["text"][:40], row["audio"]["sampling_rate"])
```

### Single language

```python
from datasets import load_dataset
ds = load_dataset(
    "leeoxiang/multi_lingo_data",
    data_files="data/samelang/zh/train-*.parquet",
    split="train",
    streaming=True,
)
```

### Full download

```bash
hf download leeoxiang/multi_lingo_data \
    --repo-type dataset \
    --include 'data/samelang/**' \
    --local-dir ./multi_lingo_data
```

## Supporting configs

- **`references`** — 1200 curated Emilia mono-lingual real-speaker clips.
- **`audio_prompts`** — 14.4 K cross-lingual synth from Step 1 (each
  real Emilia speaker cloned into 4 target langs × 3 texts).
- **`audio_prompts_expressive`** — same as above with expressive prompt
  selection; the pseudo-refs used to seed `samelang_expressive`.
