## 🎯 Quick Start

### 1. Installation

```bash
# Install from PyPI (recommended)
pip install TTS_ka

# Or install from source
git clone https://github.com/DavidTbilisi/TTS.git
cd TTS
pip install -e .
```

### 2. Basic Usage (Auto-Optimized by Default)

```bash
# Ultra-fast generation with auto-optimization (default behavior)
python -m TTS_ka "Hello, how are you today?" --lang en

# Georgian text with automatic optimization
python -m TTS_ka "გამარჯობა, როგორ ხართ?" --lang ka

# Russian text with smart chunking
python -m TTS_ka "Привет, как дела?" --lang ru
```

### 3. Clipboard Workflow (FASTEST)

```bash
# Copy any text, then run (fastest workflow):
python -m TTS_ka clipboard --lang en

# For different languages:
python -m TTS_ka clipboard --lang ka  # Georgian
python -m TTS_ka clipboard --lang ru  # Russian
```

### 4. File Processing

```bash
# Process text files directly (auto-optimized)
python -m TTS_ka document.txt --lang en

# Long files with custom settings
python -m TTS_ka large_file.txt --chunk-seconds 30 --parallel 6 --lang ru
```

## 📖 Complete Usage Guide

### Command Syntax
```
python -m TTS_ka [TEXT_SOURCE] [OPTIONS]
```

### Text Sources
- **Direct text**: `"Your text here"`
- **Clipboard**: `clipboard` (copy text first)
- **File path**: `file.txt`, `document.md`, etc.

### Essential Options

| Option | Description | Examples |
|--------|-------------|----------|
| `--lang` | Language: `ka` (Georgian), `ru` (Russian), `en` (English) | `--lang ka` |
| `--stream` | 🆕 Enable streaming playback (audio starts while generating) | `--stream` |
| `--chunk-seconds` | Chunk size in seconds (0=auto, 20-60 optimal) | `--chunk-seconds 30` |
| `--parallel` | Workers (0=auto, 2-8 recommended) | `--parallel 6` |
| `--no-play` | Skip automatic audio playback | `--no-play` |
| `--no-turbo` | Disable auto-optimization (legacy mode) | `--no-turbo` |
| `--help-full` | Show comprehensive help with examples | `--help-full` |

## 🏃‍♂️ Performance Examples

### Speed Comparison (1000 words)
- **Traditional TTS**: 25-40 seconds
- **TTS_ka Direct**: 15-25 seconds  
- **TTS_ka Turbo**: 8-15 seconds
- **TTS_ka Chunked**: 6-12 seconds ⚡
- **TTS_ka Streaming**: 🔊 2-3 seconds to first audio (NEW!)

### 🆕 Streaming Playback - Audio Starts Immediately!

The new streaming feature starts playing audio within **2-3 seconds** while the rest continues generating in the background. This provides an **85-90% reduction in perceived wait time**!

**Quick Usage:**
```bash
# Basic streaming - audio starts almost instantly!
python -m TTS_ka "Your long text..." --lang en --stream

# From file with streaming
python -m TTS_ka article.txt --lang ka --stream

# Clipboard with streaming (fastest workflow)
python -m TTS_ka clipboard --stream
```

**How It Works:**
1. Text is split into chunks (if needed)
2. Chunks generate in parallel (2-8 workers)
3. **First chunk plays immediately** (~2-3 seconds)
4. Remaining chunks continue generating in background
5. Final merged audio file is saved

**Performance:**
- **Without streaming**: Wait 10-30+ seconds for all audio
- **With streaming**: Hear audio in 2-3 seconds ⚡
- **Platform support**: Windows, Linux, macOS

**Advanced Streaming:**
```bash
# Custom chunking for optimal streaming
python -m TTS_ka longtext.txt --stream --chunk-seconds 25 --parallel 6

# Streaming without final playback
python -m TTS_ka text.txt --stream --no-play
```

### Real-World Examples

```bash
# 1. Quick phrases (instant generation)
python -m TTS_ka "Thank you very much!" --lang en
# ⚡ Completed in 2.3s (optimized)

# 2. Medium text (paragraph)
python -m TTS_ka "Lorem ipsum dolor sit amet..." --lang en  
# ⚡ Completed in 5.7s (direct)

# 3. Long document (chunked processing)
python -m TTS_ka large_document.txt --lang en
# Strategy: chunked generation, 6 workers
# ⚡ Completed in 12.4s (chunked)

# 4. Clipboard workflow (daily usage)
python -m TTS_ka clipboard --lang ka
# OPTIMIZED MODE - Georgian
# Processing: 45 words, 287 characters
# ⚡ Completed in 4.1s
```

## 🎮 AutoHotkey Integration (Windows)

### Quick Setup
1. Install [AutoHotkey v2](https://www.autohotkey.com/)
2. Create `tts_hotkeys.ahk`:

```autohotkey
; Ultra-fast TTS hotkeys
!e::  ; Alt+E - English
{
    Run("cmd /k python -m TTS_ka clipboard --lang en")
}

!r::  ; Alt+R - Russian  
{
    Run("cmd /k python -m TTS_ka clipboard --lang ru")
}

!x::  ; Alt+X - Georgian
{
    Run("cmd /k python -m TTS_ka clipboard --lang ka")
}
```

3. Double-click to run, then:
   - Copy text → **Alt+E** for English
   - Copy text → **Alt+R** for Russian  
   - Copy text → **Alt+X** for Georgian

### Daily Workflow
1. **Browse web** → Copy interesting text  
2. **Press Alt+E** → Instant speech
3. **Continue browsing** while listening

## 🔍 Troubleshooting

### Common Issues

**1. "No module named 'edge_tts'"**
```bash
pip install edge-tts>=6.1.9
```

**2. "FFmpeg not found"**
```bash
# Windows: Download and add to PATH
# macOS: brew install ffmpeg  
# Linux: sudo apt install ffmpeg
```

**3. Slow generation**
```bash
# Auto-optimization is enabled by default
python -m TTS_ka "text" --lang en

# Reduce parallel workers if network issues
python -m TTS_ka "text" --parallel 2 --lang en

# Use legacy mode only if needed
python -m TTS_ka "text" --no-turbo --lang en
```

**4. Empty clipboard**
```bash
# Ensure text is copied first
# Then run: python -m TTS_ka clipboard --turbo --lang en
```

### Performance Optimization

**For Maximum Speed:**
```bash
# Use these exact settings for best performance (auto-optimized by default)
python -m TTS_ka clipboard --chunk-seconds 30 --parallel 6 --lang en
```

**For System with Limited Resources:**
```bash
# Reduce workers and chunk size
python -m TTS_ka text --parallel 2 --chunk-seconds 60 --lang en
```

## 📊 Performance Benchmarks

### Text Length vs Generation Time

| Words | Direct Mode | Turbo Mode | Chunked (6 workers) |
|-------|-------------|------------|---------------------|
| 10-50 | 2-4s | 1-3s | 2-4s |
| 100-300 | 8-12s | 5-8s | 4-6s |
| 500-1000 | 18-25s | 12-15s | 8-12s |
| 1000+ | 30-45s | 18-25s | 10-18s |

### Optimal Settings by Text Length

```bash
