# Parakeet

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 Paddle Fluid dynamic graph, with the support of many influential TTS models proposed by [Baidu Research](http://research.baidu.com) and other academic institutions.

## Installation

### Install Paddlepaddle

See [install](https://www.paddlepaddle.org.cn/install/quick) for more details. This repo requires paddlepaddle's version is above 1.7.

### Install Parakeet

```bash
# git clone this repo first
cd Parakeet
pip install -e .
```

### Install CMUdict for nltk

CMUdict from nltk is used to transform text into phonemes.

```python
import nltk
nltk.download("cmudict")
```

If you have completed all the above installations, but still report an error at runtime：

``` OSError: sndfile library not found ```

You need to install ```libsndfile``` using your distribution’s package manager. e.g. install via:

``` sudo apt-get install libsndfile1 ```

## Supported models

- [Deep Voice 3: Scaling Text-to-Speech with Convolutional Sequence Learning](https://arxiv.org/abs/1710.07654)
- [Neural Speech Synthesis with Transformer Network](https://arxiv.org/abs/1809.08895)
- [FastSpeech: Fast, Robust and Controllable Text to Speech](https://arxiv.org/abs/1905.09263).
