LJSpeech — Mimi Codes

Pre-extracted Kyutai Mimi neural-codec tokens for the LJSpeech corpus — 13,100 English utterances from a single female speaker reading public-domain audiobook passages (~24 hours).

This dataset contains codes only, not audio. For waveforms, go to the original LJSpeech release; these codes are designed to be loaded alongside it for training Mimi-based speech models without paying the ~1 hour of GPU extraction cost.

Schema

One row per utterance:

Column	Type	Notes
`id`	string	e.g. `LJ001-0001`
`text`	string	normalized transcript, original mixed-case preserved
`codes`	`int16[k=8][n_frames]`	Mimi codebook indices @ 12.5 fps
`n_frames`	int32	= `codes.shape[1]`
`k_codebooks`	int32	= 8

Extraction details

Codec: kyutai/mimi @ 24 kHz, 12.5 fps
Codebooks: all 8 extracted. Slice codes[:k] if you want fewer (Mimi's codebooks are ordered by importance; the first few capture most of the signal).
Codebook size: 2048 per codebook → values stored as int16
Transcripts: the normalized column from metadata.csv (punctuation preserved, expanded numerics/abbreviations). Original mixed-case is kept — apply .lower() at load time if your model expects lowercase (e.g. to reproduce Wren-TTS training).

Usage

from datasets import load_dataset
import torch

ds = load_dataset("shangeth/ljspeech-mimi-codes", split="train")

ex    = ds[0]
codes = torch.tensor(ex["codes"], dtype=torch.long)   # [8, n_frames]
print(ex["id"], "→", ex["text"][:60])
print("codes:", codes.shape, "duration:", codes.shape[1] / 12.5, "s")

# Use only the first 3 codebooks (e.g. for a smaller model):
codes_3 = codes[:3]

Decode back to audio with the Mimi decoder:

from transformers import MimiModel
mimi = MimiModel.from_pretrained("kyutai/mimi").cuda().eval()
with torch.no_grad():
    wav = mimi.decode(codes.unsqueeze(0).cuda()).audio_values[0].cpu()
# wav is [1, T] @ 24 kHz
