# Affective TTS & Soundscape Synthesis

Affective TTS tool for [SHIFT Horizon](https://shift-europe.eu/).
  - Synthesizes affective speech with sound scape, trees, water, leaves, background from plain text or subtitles (.srt) & overlays it to videos.
  - `134` build-in affective voices available, tuned for [StyleTTS2](https://github.com/yl4579/StyleTTS2).
  - [GitHub](https://github.com/audeering/shift)

### Available Voices

<a href="https://audeering.github.io/shift/">Listen to available voices!</a>

## Flask API

Install

```
virtualenv --python=python3 ~/.envs/.my_env
source ~/.envs/.my_env/bin/activate
cd shift/
pip install -r requirements.txt
```

Start Flask

```
CUDA_DEVICE_ORDER=PCI_BUS_ID HF_HOME=./hf_home CUDA_VISIBLE_DEVICES=2 python api.py
```

## Inference

The following need `api.py` to be running, e.g. `.. on computeXX`. 

**Text 2 Speech**

```python
# Basic TTS - See Available Voices
python tts.py --text sample.txt --voice "en_US/m-ailabs_low#mary_ann" --affective

# voice cloning
python tts.py --text sample.txt --native assets/native_voice.wav
```

**Image 2 Video**

```python
# Make video narrating an image - All above TTS args apply also here!
python tts.py --text sample.txt --image assets/image_from_T31.jpg
```

**Video 2 Video**

```python
# Video Dubbing - from time-stamped subtitles (.srt)
python tts.py --text assets/head_of_fortuna_en.srt --video assets/head_of_fortuna.mp4

# Video narration - from text description (.txt)
python tts.py --text assets/head_of_fortuna_GPT.txt --video assets/head_of_fortuna.mp4
```

## Examples
