## What it does

The skill shells out to `uvx zai-tts` and writes a wav file. Pass a string with `-t` or a whole file with `-f`, and set the output path with `-o`. Speed and volume come from `--speed` and `--volume`.

Pick a voice with `--voice`. Three system voices ship with it: `system_001` (Lila), `system_002` (Chloe) and `system_003` (Ethan). Run `uvx zai-tts -l` to list everything available. Custom voices have to be cloned on `audio.z.ai` first.

Two environment variables are required before the first run: `ZAI_AUDIO_USERID` and `ZAI_AUDIO_TOKEN`. Log in to `audio.z.ai`, open the developer console with F12 and run `localStorage['auth-storage']` to get both values. Skip that step and the command fails, so set them up first.

## When to use it
- turn a long agent answer into audio for listening on the move
- generate a wav from a text file in one command
- swap voice or speed for a specific recording
- list the available voices before committing to one
- use a pre-cloned voice for speech generation

## Example prompts
- read this text aloud with tts and save it as wav
- make audio from notes.txt using the system_002 voice
- speak the answer at speed 1.5 and volume 2

# Zai-TTS

Generate high-quality text-to-speech audio using GLM-TTS service via the `uvx zai-tts` command.
Before using this skill, you need to configure the environment variables `ZAI_AUDIO_USERID` and `ZAI_AUDIO_TOKEN`,
which can be obtained by login `audio.z.ai` and executing `localStorage['auth-storage']` in the console via F12 Developer Tools.

## Usage
```shell
uvx zai-tts -t "{msg}" -o {tempdir}/{filename}.wav
uvx zai-tts -f path/to/file.txt -o {tempdir}/{filename}.wav
```

## Changing speed, volume
```shell
uvx zai-tts -t "{msg}" -o {tempdir}/{filename}.wav --speed 1.5
uvx zai-tts -t "{msg}" -o {tempdir}/{filename}.wav --speed 1.5 --volume 2
```

## Changing the voice
```shell
uvx zai-tts -t "{msg}" -o {tempdir}/{filename}.wav --voice system_002
```

## Available voices
`system_001`: Lila.  A cheerful, standard-pronunciation female voice
`system_002`: Chloe. A gentle, elegant, intelligent female voice
`system_003`: Ethan. A sunny, standard-pronunciation male voice

Retrieve all available voices using shell commands:
```shell
uvx zai-tts -l
```
If you want to use custom voices, please complete voice cloning on the website `audio.z.ai` first.
