# YakYak
YakYak is a utility for the local generation of synthetic voice through use of Wyoming-Piper. It can be used from the command line or called from python. It opens a TCP socket to Wyoming-Piper running in Docker anywhere on your local area network. It scales to run efficiently on large multi-core computers or small single board computers.

## Install YakYak, Docker Compose & FFMPEG
To install YakYak, a python virtual environment is recommended.

### Step 1, create a python virtual environment and activate it
```bash
cd some_directory  
sudo apt install python3.8-venv
python3 -m venv .venv  
source .venv/bin/activate  
```

### Step 2, install the YakYak package
```bash
pip install yakyak
```

### Step 3, Install ffmpeg
Install ffmpeg for mac
```bash
brew install ffmpeg
```
Install ffmpeg for Ubuntu
```bash
sudo apt install ffmpeg
```

### Setup wyoming-piper in docker, on your local area network.   
If you don't already have docker, or better yet docker-desktop, you can download and install it from [docker.com](https://docker.com).

If you don't already have a wyoming-piper __docker-compose.yml__ file, create one using YakYak.  Warning, this will overwrite an existing docker-compose.yml file.

```bash
yakyak --docker > docker-compose.yml
```
 
Now you can start wyoming-piper in a docker container
```bash
docker compose up -d --force-recreate
```
 
## Test installation
It will take a little longer the first time running YakYak, 
the Wyoming-Piper app needs time to download voice files.
```bash
piper -h localhost -t mp3
```
 
Observe successful test results  

```text
INFO:root:Server localhost:10200 is online
INFO:root:Success, test: mp3
```

## How to use YakYak from the command line
As with many Linux applications, YakYak supports standard in, and standard out. It also supports file input with the -i command and -o for file output. For a complete set of commands type yakyak --help.
```bash
yakyak --help
```

Create an mp3 file with "Hello world"  
```bash
echo Hello world | yakyak -f mp3 -o hello_world.mp3
```

If you are on Linux and have aplay installed, you can do this:  
```bash
echo Hello world | yakyak | aplay
```
This assumes that Docker is running on the same machine.

If Docker is running on a different machine on your network, you can do this:  
```bash
echo Hello world | yakyak --host a_different_machine.local | aplay
```

## How to use YakYak from Python
Create the file `test_yakyak.py` with the following content:  
```python
from yakyak import is_server_online, piper_tts_server

print(f"{is_server_online(
        'localhost', 
        10200, 
        )=}")

print(f"{piper_tts_server(
        'localhost', 
        10200, 
        'Hello World',
        'hello_world.mp3',
        'mp3',
        'en_US-amy-medium'
        )=}")
```
Now test it
```bash
python3 test_yakyak.py  
```
Observe that the server is online and a file hello_world.mp3 is created. Play the mp3 and you will hear "Hello world".

```text
run.py 
check_ffmpeg_version()='ffmpeg version 6.0 Copyright (c) 2000-2023 the FFmpeg developers'
is_server_online(
        'localhost', 
        10200, 
        )=True
INFO:root:Server localhost:10200 is online
run_test(
        'localhost', 
        10200, 
        'mp3',
        )=(True, 'Success, test: mp3')
INFO:root:Success, test: mp3
await piper_tts_server(
            'localhost', 
            10200, 
            'Hello World',
            'run_test.mp3',
            'mp3',
            'en_US-amy-medium'
            )=None

Process finished with exit code 0
```
