# TTS (Text To Speech)
## Introduction
Text-to-speech (TTS) is a natural language modeling process that requires changing units of text into units of speech for audio presentation.
This demo is an implementation to generate audio from the given text. It can be done by a single command or a few lines in python using `PaddleSpeech`.
## Usage
### 1. Installation
see [installation](https://github.com/PaddlePaddle/PaddleSpeech/blob/develop/docs/source/install.md).
You can choose one way from easy, meduim and hard to install paddlespeech.
### 2. Prepare Input
The input of this demo should be a text of the specific language that can be passed via argument.
### 3. Usage
- Command Line (Recommended)
The default acoustic model is `Fastspeech2`, and the default vocoder is `HiFiGAN`, the default inference method is dygraph inference.
- Chinese
```bash
paddlespeech tts --input "你好,欢迎使用百度飞桨深度学习框架!"
```
- Batch Process
```bash
echo -e "1 欢迎光临。\n2 谢谢惠顾。" | paddlespeech tts
```
- Chinese, use `SpeedySpeech` as the acoustic model
```bash
paddlespeech tts --am speedyspeech_csmsc --input "你好,欢迎使用百度飞桨深度学习框架!"
```
- Chinese, multi-speaker
You can change `spk_id` here.
```bash
paddlespeech tts --am fastspeech2_aishell3 --voc pwgan_aishell3 --input "你好,欢迎使用百度飞桨深度学习框架!" --spk_id 0
```
- English
```bash
paddlespeech tts --am fastspeech2_ljspeech --voc pwgan_ljspeech --lang en --input "hello world"
```
- English, multi-speaker
You can change `spk_id` here.
```bash
paddlespeech tts --am fastspeech2_vctk --voc pwgan_vctk --input "hello, boys" --lang en --spk_id 0
```
- Chinese English Mixed, multi-speaker
You can change `spk_id` here.
```bash
# The `am` must be `fastspeech2_mix`!
# The `lang` must be `mix`!
# The voc must be chinese datasets' voc now!
# spk 174 is csmcc, spk 175 is ljspeech
paddlespeech tts --am fastspeech2_mix --voc hifigan_csmsc --lang mix --input "热烈欢迎您在 Discussions 中提交问题,并在 Issues 中指出发现的 bug。此外我们非常希望您参与到 Paddle Speech 的开发中!" --spk_id 174 --output mix_spk174.wav
paddlespeech tts --am fastspeech2_mix --voc hifigan_aishell3 --lang mix --input "热烈欢迎您在 Discussions 中提交问题,并在 Issues 中指出发现的 bug。此外我们非常希望您参与到 Paddle Speech 的开发中!" --spk_id 174 --output mix_spk174_aishell3.wav
paddlespeech tts --am fastspeech2_mix --voc pwgan_csmsc --lang mix --input "我们的声学模型使用了 Fast Speech Two, 声码器使用了 Parallel Wave GAN and Hifi GAN." --spk_id 175 --output mix_spk175_pwgan.wav
paddlespeech tts --am fastspeech2_mix --voc hifigan_csmsc --lang mix --input "我们的声学模型使用了 Fast Speech Two, 声码器使用了 Parallel Wave GAN and Hifi GAN." --spk_id 175 --output mix_spk175.wav
```
