-## Installation
-
-### Install paddlepaddle
-This implementation requires the latest develop version of paddlepaddle. You can either download the compiled package or build paddle from source.
-1. Install the compiled package, via pip, conda or docker. See [**Installation Mannuals**](https://www.paddlepaddle.org.cn/documentation/docs/en/beginners_guide/install/index_en.html) for more details.
-
-2. Build paddlepaddle from source. See [**Compile From Source Code**](https://www.paddlepaddle.org.cn/documentation/docs/en/beginners_guide/install/compile/fromsource_en.html) for more details. Note that if you want to enable data parallel training for multiple GPUs, you should set `-DWITH_DISTRIBUTE=ON` with cmake.
-
-### Install parakeet
-You can choose to install via pypi or clone the repository and install manually.
-
-1. Install via pypi.
-   ```bash
-   pip install parakeet
-   ```
-
-2. Install manually.
-   ```bash
-   git clone <url>
-   cd Parakeet/
-   pip install -e .

-### Download cmudict for nltk
-You also need to download cmudict for nltk, because convert text into phonemes with `cmudict`.
-
-```python
-import nltk
-nltk.download("punkt")
-nltk.download("cmudict")
-```
