# Zvukogram TTS

Speech generation via Zvukogram API with SSML markup support.

## Requirements

To use this skill, you need:
- **Zvukogram API token** — get it at https://zvukogram.com/
- **Zvukogram account email**

### Setup

Create file `~/.config/zvukogram/config.json`:
```bash
mkdir -p ~/.config/zvukogram
```

```json
{
  "token": "your_api_token_here",
  "email": "your_email@example.com"
}
```

Or use environment variables:
```bash
export ZVUKOGRAM_TOKEN=your_api_token_here
export ZVUKOGRAM_EMAIL=your_email@example.com
```

## Quick Start

```bash
# Simple TTS
python3 scripts/tts.py --text "Hello, world!" --voice Алена --output hello.mp3

# With +20% speed
python3 scripts/tts.py --text "Fast text" --voice Алена --speed 1.2 --output fast.mp3

# Check balance
python3 scripts/balance.py
```

## Features

- **TTS generation** — text to speech
- **SSML support** — stress marks, pauses, speed
- **Audio merging** — combine fragments via ffmpeg
- **Transcription** — proper pronunciation of English words

## SSML Markup

### Stress Marks
Use `+` before stressed vowel:
```
З+амок — stress on "a"
зам+ок — stress on "o"
```

### Aliases (Transcription)
```xml
<sub alias="Оупен Эй Ай">OpenAI</sub>
<sub alias="Самсунг">Samsung</sub>
<sub alias="Ал+ьтман">Альтман</sub>
```

### Speed
```xml
<prosody rate="1.2">20% faster</prosody>
<prosody rate="fast">Fast text</prosody>
```

### Pauses
```xml
<break time="500ms"/>
```
