Parakeet aims to provide a flexible, efficient and state-of-the-art text-to-speech toolkit for the open-source community. It is built on PaddlePaddle Fluid dynamic graph and includes many influential TTS models proposed by [Baidu Research](http://research.baidu.com) and other research groups.

See [install](https://www.paddlepaddle.org.cn/install/quick) for more details. This repo requires PaddlePaddle **1.8.2** or above.
See [install](https://www.paddlepaddle.org.cn/install/quick) for more details. This repo requires PaddlePaddle **2.0.0.rc1** or above.
### Install Parakeet
```bash
pip install -U paddle-parakeet
```
or
```bash
git clone https://github.com/PaddlePaddle/Parakeet
cd Parakeet
pip install -e .
```
### Install CMUdict for nltk
CMUdict from nltk is used to transform text into phonemes.
```python
import nltk
nltk.download("punkt")
nltk.download("cmudict")
```

## Examples
Entries to the introduction, and the launch of training and synthsis for different example models:
- [>>> WaveFlow](./examples/waveflow)
- [>>> Clarinet](./examples/clarinet)
- [>>> WaveNet](./examples/wavenet)
- [>>> Deep Voice 3](./examples/deepvoice3)
- [>>> Transformer TTS](./examples/transformer_tts)
- [>>> FastSpeech](./examples/fastspeech)
- [>>> Tacotron2](./examples/tacotron2)
## Pre-trained models and audio samples
## Audio samples
Parakeet also releases some well-trained parameters for the example models, which can be accessed in the following tables. Each column of these tables lists resources for one model, including the url link to the pre-trained model, the dataset that the model is trained on, and synthesized audio samples based on the pre-trained model. Click each model name to download, then you can get the compressed package which contains the pre-trained model and the `yaml` config describing how the model is trained.
### TTS models (Acoustic Model + Neural Vocoder)
#### Vocoders
We provide the model checkpoints of WaveFlow with 64, 96 and 128 residual channels, ClariNet and WaveNet.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Note:** The input mel spectrogams are from validation dataset, which are not seen during training.
#### TTS models
We also provide checkpoints for different end-to-end TTS models, and present the synthesized audio examples for some randomly chosen famous quotes. The corresponding texts are displayed as follows.
||Text | From |
|:-:|:-- | :--: |
0|*Life was like a box of chocolates, you never know what you're gonna get.* | *Forrest Gump* |
1|*With great power there must come great responsibility.* | *Spider-Man*|
2|*To be or not to be, thats a question.*|*Hamlet*|
3|*Death is just a part of life, something we're all destined to do.*| *Forrest Gump*|
4|*Dont argue with the people of strong determination, because they may change the fact!*| *William Shakespeare* |
Users have the option to use different vocoders to convert the linear/mel spectrogam to the raw audio in TTS models. Taking this into account, we are going to release the checkpoints for TTS models adapted to different vocoders, including the [Griffin-Lim](https://ieeexplore.ieee.org/document/1164317) algorithm and some neural vocoders.
