voicepeak-cli

日本語 | English

A command-line interface wrapper for VOICEPEAK text-to-speech software with preset management and automatic audio playback.

What's Different from the Original VOICEPEAK Command?

This wrapper enhances the original VOICEPEAK CLI with several powerful features:

• 🎵 Auto-play with mpv - Automatically plays generated audio when no output file is specified
• 📝 Voice presets - Save and reuse combinations of narrator, emotions, and pitch settings
• 📜 Long text support - Automatically splits texts longer than 140 characters and merges audio chunks
• 🔧 Advanced playback modes - Choose between batch (generate all → merge → play) or sequential (generate → play one by one)
• 🔄 Pipe input support - Accept text from stdin: echo "text" | vp
• 🔇 Clean output - Suppresses technical output by default (use --verbose to see debug info)
• ⚙️ Configuration file - Store your preferred settings in ~/.config/vp/config.toml

Key Benefits

• Enhanced Workflow: No need to manually save and play audio files - just run and listen
• Batch Processing: Handle long documents without worrying about character limits
• Flexible Input: Works with direct text, files, or piped input from other commands
• Personalization: Save your favorite voice configurations for consistent results
• Professional Output: Clean interface with optional verbose mode for debugging

Requirements

• macOS
• VOICEPEAK installed at /Applications/voicepeak.app/
• mpv for audio playback (install via Homebrew: brew install mpv)
• ffmpeg for batch mode and multi-chunk file output (install via Homebrew: brew install ffmpeg)

Usage

Basic Usage

# Simple text-to-speech (requires preset or --narrator)
vp "こんにちは、世界！"

# With explicit narrator
vp "こんにちは、世界！" --narrator "夏色花梨"

# Save to file instead of auto-play
vp "こんにちは、世界！" --narrator "夏色花梨" -o output.wav

# Read from file
vp -t input.txt --narrator "夏色花梨"

# Pipe input
echo "こんにちは、世界！" | vp --narrator "夏色花梨"
cat document.txt | vp -p karin-happy

Using Presets

# List available presets
vp --list-presets

# Use a preset
vp "こんにちは、世界！" -p karin-happy

# Override preset settings
vp "こんにちは、世界！" -p karin-normal --emotion "happy=50"

Voice Controls

# Control speech parameters
vp "こんにちは、世界！" --narrator "夏色花梨" --speed 120 --pitch 50

# List available narrators
vp --list-narrator

# List emotions for a specific narrator
vp --list-emotion "夏色花梨"

Text Length Handling

# Allow automatic text splitting (default)
vp "very long text..."

# Strict mode: reject texts longer than 140 characters
vp "text" --strict-length

Playback Modes

# Batch mode: generate all chunks first, merge, then play (default)
vp "long text" --playback-mode batch

# Sequential mode: generate and play chunks one by one
vp "long text" --playback-mode sequential

# Long text file output (uses ffmpeg to merge chunks)
vp "very long text" -o output.wav

# For sequential playback without ffmpeg
vp "long text" --playback-mode sequential

Configuration

Configuration is stored in ~/.config/vp/config.toml. The file is automatically created on first run.

Example Configuration

default_preset = "karin-custom"

[[presets]]
name = "karin-custom"
narrator = "夏色花梨"
emotions = [
    { name = "hightension", value = 10 },
    { name = "sasayaki", value = 20 },
]
pitch = 30
speed = 120

[[presets]]
name = "karin-normal"
narrator = "夏色花梨"
emotions = []

[[presets]]
name = "karin-happy"
narrator = "夏色花梨"
emotions = [{ name = "hightension", value = 50 }]

Configuration Fields

• default_preset: Optional. Preset to use when no -p option is specified
• presets: Array of voice presets

Preset Fields

• name: Unique preset identifier
• narrator: Voice narrator name
• emotions: Array of emotion parameters with name and value
• pitch: Optional pitch adjustment (-300 to 300)
• speed: Optional speed adjustment (50 to 200)

Command-Line Options

Usage: vp [OPTIONS] [TEXT]

Arguments:
  [TEXT]  Text to say (or pipe from stdin)

Options:
  -t, --text <FILE>              Text file to say
  -o, --out <FILE>               Path of output file (optional - will play with mpv if not specified)
  -n, --narrator <NAME>          Name of voice
  -e, --emotion <EXPR>           Emotion expression (e.g., happy=50,sad=50)
  -p, --preset <NAME>            Use voice preset
      --list-narrator            Print voice list
      --list-emotion <NARRATOR>  Print emotion list for given voice
      --list-presets             Print available presets
      --speed <VALUE>            Speed (50 - 200)
      --pitch <VALUE>            Pitch (-300 - 300)
      --strict-length            Reject input longer than 140 characters (default: false, allows splitting)
      --playback-mode <MODE>     Playback mode: sequential or batch (default: batch)
  -v, --verbose                  Enable verbose output (show VOICEPEAK debug messages)
  -h, --help                     Print help
  -V, --version                  Print version

Parameter Priority

When multiple sources specify the same parameter, the priority order is:

1. Command-line options (highest priority)
2. Preset values
3. Default values / none (lowest priority)

For example:

• vp "text" -p my-preset --pitch 100 uses pitch=100 (CLI override)
• vp "text" -p my-preset uses preset's pitch value
• vp "text" --narrator "voice" uses no pitch adjustment
