-**Kokoro** is a frontier TTS model for its size of **82 million parameters** (text in/audio out).
-
-On 25 Dec 2024, Kokoro v0.19 weights were permissively released in full fp32 precision along with 2 voicepacks (Bella and Sarah), all under an Apache 2.0 license.
-
-At the time of release, Kokoro v0.19 was the #1🥇 ranked model in [TTS Spaces Arena](https://huggingface.co/spaces/Pendrokar/TTS-Spaces-Arena). With 82M params trained for <20 epochs on <100 total hours of audio, Kokoro achieved higher Elo in this single-voice Arena setting over models such as:
-- XTTS v2: 467M, CPML, >10k hours
-- Edge TTS: Microsoft, proprietary
-- MetaVoice: 1.2B, Apache, 100k hours
-- Parler Mini: 880M, Apache, 45k hours
-- Fish Speech: ~500M, CC-BY-NC-SA, 1M hours
-
-Kokoro's ability to top this Elo ladder using relatively low compute and data suggests that the scaling law for traditional TTS models might have a steeper slope than previously expected.
-
-You can find a hosted demo at [hf.co/spaces/hexgrad/Kokoro-TTS](https://huggingface.co/spaces/hexgrad/Kokoro-TTS).
-
-### Usage
-
-The following can be run in a single cell on [Google Colab](https://colab.research.google.com/).
-```py
-# 1️⃣ Install dependencies silently
-!git clone https://huggingface.co/hexgrad/Kokoro-82M
-%cd Kokoro-82M
-!apt-get -qq -y install espeak-ng > /dev/null 2>&1
-!pip install -q phonemizer torch transformers scipy munch
-
-# 2️⃣ Build the model and load the default voicepack
-from models import build_model
-import torch
-device = 'cuda' if torch.cuda.is_available() else 'cpu'
-MODEL = build_model('kokoro-v0_19.pth', device)
-VOICEPACK = torch.load('voices/af.pt', weights_only=True).to(device)
-
-# 3️⃣ Call generate, which returns a 24khz audio waveform and a string of output phonemes
-from kokoro import generate
-text = "How could I know? It's an unanswerable question. Like asking an unborn child if they'll lead a good life. They haven't even been born."
-audio, out_ps = generate(MODEL, text, VOICEPACK)
-
-# 4️⃣ Display the 24khz audio and print the output phonemes
-from IPython.display import display, Audio
-display(Audio(data=audio, rate=24000, autoplay=True))
-print(out_ps)
-```
-This inference code was quickly hacked together on Christmas Day. It is not clean code and leaves a lot of room for improvement. If you'd like to contribute, feel free to open a PR.

-
-**Architected by:** Li et al @ https://github.com/yl4579/StyleTTS2
-
-**Trained by**: `@rzvzn` on Discord
-
-**Supported Languages:** English
-
-**Model SHA256 Hash:** `3b0c392f87508da38fad3a2f9d94c359f1b657ebd2ef79f9d56d69503e470b0a`
-
-**Releases:**

-- 26 Dec 2024: `am_adam`, `am_michael`
-
-**Licenses:**
-- Apache 2.0 weights in this repository
-- MIT inference code in [spaces/hexgrad/Kokoro-TTS](https://huggingface.co/spaces/hexgrad/Kokoro-TTS) adapted from [yl4579/StyleTTS2](https://github.com/yl4579/StyleTTS2)
-- GPLv3 dependency in [espeak-ng](https://github.com/espeak-ng/espeak-ng)
-

-### Evaluation
-
-**Metric:** Elo rating

-**Leaderboard:** [hf.co/spaces/Pendrokar/TTS-Spaces-Arena](https://huggingface.co/spaces/Pendrokar/TTS-Spaces-Arena)

-
-The voice ranked in the Arena is a 50-50 mix of Bella and Sarah. For your convenience, this mix is included in this repository as `af.pt`, but you can trivially reproduce it like this:
-
-```py
-import torch
-bella = torch.load('voices/af_bella.pt', weights_only=True)
-sarah = torch.load('voices/af_sarah.pt', weights_only=True)
-af = torch.mean(torch.stack([bella, sarah]), dim=0)
-assert torch.equal(af, torch.load('voices/af.pt', weights_only=True))
-```
-
-### Training Details
-
-**Compute:** Kokoro was trained on A100 80GB vRAM instances rented from [Vast.ai](https://cloud.vast.ai/?ref_id=79907) (referral link). Vast was chosen over other compute providers due to its competitive on-demand hourly rates. The average hourly cost for the A100 80GB vRAM instances used for training was below $1/hr per GPU, which was around half the quoted rates from other providers at the time.
-
-**Data:** Kokoro was trained exclusively on **permissive/non-copyrighted audio data** and IPA phoneme labels. Examples of permissive/non-copyrighted audio include:
-- Public domain audio
-- Audio licensed under Apache, MIT, etc
-- Synthetic audio<sup>[1]</sup> generated by closed<sup>[2]</sup> TTS models from large providers<br/>
-[1] https://copyright.gov/ai/ai_policy_guidance.pdf<br/>
-[2] No synthetic audio from open TTS models or "custom voice clones"
-
-**Epochs:** Less than **20 epochs**
-
-**Total Dataset Size:** Less than **100 hours** of audio
-
-### Limitations
-
-Kokoro v0.19 is limited in some ways, in its training set and architecture:
-- [Data] Lacks voice cloning capability, likely due to small <100h training set
-- [Arch] Relies on external g2p (espeak-ng), which introduces a class of g2p failure modes
-- [Data] Training dataset is mostly long-form reading and narration, not conversation
-- [Arch] At 82M params, Kokoro almost certainly falls to a well-trained 1B+ param diffusion transformer, or a many-billion-param MLLM like GPT-4o / Gemini 2.0 Flash
-- [Data] Multilingual capability is architecturally feasible, but training data is almost entirely English
-
-**Will the other voicepacks be released?** There is currently no release date scheduled for the other voicepacks, but in the meantime you can try them in the hosted demo at [hf.co/spaces/hexgrad/Kokoro-TTS](https://huggingface.co/spaces/hexgrad/Kokoro-TTS).
