README

A Laravel package for integrating Microsoft's VibeVoice AI voice synthesis technology. Generate high-quality, multi-speaker text-to-speech audio in your Laravel applications.

Features

• Single speaker text-to-speech generation
• Multi-speaker conversation synthesis (up to 4 speakers)
• Real-time streaming audio generation
• Eloquent model integration via trait
• Asynchronous audio generation via Laravel queues
• Configurable storage (local, S3, etc.)
• Artisan commands for CLI usage

Requirements

• PHP 8.1+
• Laravel 10.x or 11.x
• A running VibeVoice API server (see vibevoice-api)

Installation

Install the package via Composer:

composer require bitsoftsol/laravel-vibevoice

Publish the configuration file:

php artisan vendor:publish --tag=vibevoice-config

Add the following environment variables to your .env file:

VIBEVOICE_API_URL=http://your-api-server:8000
VIBEVOICE_API_KEY=your-api-key
VIBEVOICE_DEFAULT_VOICE=en-US-female-1

Quick Start

Basic Usage

use BitsoftSol\VibeVoice\Facades\VibeVoice;

// Generate audio from text
$result = VibeVoice::generate('Hello, welcome to our application!');

// Access the audio content
$audioContent = $result->getAudioContent();
$duration = $result->duration; // in seconds

// Generate and save to storage
$path = VibeVoice::generateAndSave('Hello world!', 'greeting');
// Returns: vibevoice/greeting.mp3

Using a Specific Voice

// List available voices
$voices = VibeVoice::voices();

foreach ($voices as $voice) {
    echo "{$voice->id}: {$voice->name} ({$voice->gender})\n";
}

// Generate with a specific voice
$result = VibeVoice::generate('Hello!', 'en-US-male-1');

Multi-Speaker Conversations

use BitsoftSol\VibeVoice\DTOs\ConversationLine;

$conversation = [
    new ConversationLine(text: 'Hello, how can I help you today?', voice: 'en-US-female-1', speaker: 'Agent'),
    new ConversationLine(text: 'I have a question about my order.', voice: 'en-US-male-1', speaker: 'Customer'),
    new ConversationLine(text: 'Of course! Let me look that up for you.', voice: 'en-US-female-1', speaker: 'Agent'),
];

$result = VibeVoice::conversation($conversation);

// Or using arrays
$conversation = [
    ['text' => 'Hello!', 'voice' => 'en-US-female-1'],
    ['text' => 'Hi there!', 'voice' => 'en-US-male-1'],
];

$path = VibeVoice::conversationAndSave($conversation, 'dialogue');

Streaming Audio

// Stream audio chunks in real-time
foreach (VibeVoice::stream('This is a long text to stream...') as $chunk) {
    // Process each audio chunk
    echo $chunk;
}

Model Integration

Add text-to-speech capabilities to your Eloquent models using the HasVoiceContent trait.

Migration

Schema::create('articles', function (Blueprint $table) {
    $table->id();
    $table->string('title');
    $table->text('content');
    $table->string('audio_file')->nullable();
    $table->float('audio_duration')->nullable();
    $table->string('voice_id')->nullable();
    $table->timestamps();
});

Model Setup

use BitsoftSol\VibeVoice\Traits\HasVoiceContent;
use Illuminate\Database\Eloquent\Model;

class Article extends Model
{
    use HasVoiceContent;

    protected $fillable = ['title', 'content', 'voice_id'];

    // Specify which field contains the text to convert
    public function getVoiceTextField(): string
    {
        return 'content';
    }

    // Optionally specify a default voice for this model
    public function getVoiceId(): ?string
    {
        return $this->voice_id ?? 'en-US-female-1';
    }
}

Usage

$article = Article::create([
    'title' => 'My Article',
    'content' => 'This is the article content that will be converted to speech.',
]);

// Generate audio synchronously
$article->generateAudio();

// Generate audio asynchronously via queue
$article->generateAudioAsync();

// Check if audio exists
if ($article->hasAudio()) {
    $url = $article->getAudioUrl();
    $duration = $article->getFormattedAudioDuration(); // "02:30.50"
}

// Regenerate audio (deletes old file and creates new)
$article->regenerateAudio();

// Delete audio file
$article->deleteAudio();

Async Processing

Queue Jobs

use BitsoftSol\VibeVoice\Facades\VibeVoice;

// Generate audio in background
VibeVoice::generateAsync('Long text to process...', 'en-US-female-1', 'output-file');

// Generate conversation in background
VibeVoice::conversationAsync($lines, 'conversation-output');

Events

Listen for audio generation events:

// In EventServiceProvider or event listener
use BitsoftSol\VibeVoice\Events\VoiceGenerated;
use BitsoftSol\VibeVoice\Events\VoiceGenerationFailed;

Event::listen(VoiceGenerated::class, function ($event) {
    $path = $event->path;
    $duration = $event->result->duration;

    // Update related model if available
    if ($model = $event->getModel()) {
        // Model was updated automatically
    }
});

Event::listen(VoiceGenerationFailed::class, function ($event) {
    Log::error('Voice generation failed', [
        'error' => $event->getErrorMessage(),
        'text' => $event->text,
    ]);
});

use BitsoftSol\VibeVoice\Exceptions\AuthenticationException;
use BitsoftSol\VibeVoice\Exceptions\ConnectionException;
use BitsoftSol\VibeVoice\Exceptions\GenerationException;
use BitsoftSol\VibeVoice\Exceptions\RateLimitException;

try {
    $result = VibeVoice::generate($text);
} catch (AuthenticationException $e) {
    // Invalid or missing API key
} catch (ConnectionException $e) {
    // Cannot connect to API server
} catch (RateLimitException $e) {
    $retryAfter = $e->getRetryAfter(); // seconds to wait
} catch (GenerationException $e) {
    // Invalid input or generation failed
    $context = $e->getContext();
}
