Edge TTS

Overview

Edge TTS is a powerful Text-to-Speech (TTS) package for PHP that leverages Microsoft's Edge capabilities. This package allows you to synthesize speech from text and manage voice options easily through a command-line interface (CLI).

Features

  • Text-to-Speech: Convert text into natural-sounding speech using Microsoft Edge's TTS capabilities.
  • Multiple Voices: Access a variety of voices to suit your project's needs.
  • Audio Export Options: Export synthesized audio in different formats (raw, base64, or directly to a file).
  • Command-Line Interface: Use a simple CLI for easy access to functionality.
  • Easy Integration: Modular structure allows for easy inclusion in existing PHP projects.

Installation

You can install Edge TTS via Composer. Run the following command in your terminal:

composer require afaya/edge-tts

Usage

Command-Line Interface To synthesize speech from text, use the following command:

php .\vendor\bin\edge-tts edge-tts:synthesize --text "Hello, world!"

To list available voices, run:

php .\vendor\bin\edge-tts edge-tts:voice-list

Integration into Your Project

To use Edge TTS in your PHP project, include the autoload file:

<?php

require __DIR__ . '/vendor/autoload.php';

use Afaya\EdgeTTS\Service\EdgeTTS;

// Initialize the EdgeTTS service
$tts = new EdgeTTS();

// Get voices
$voices = $tts->getVoices();  
// var_dump($voices);  // array -> use ShortName with the name of the voice

// Synthesize text with options for voice, rate, volume, and pitch
$tts->synthesize("Hello, world!", 'en-US-AriaNeural', [
    'rate' => '0%',       // Speech rate (range: -100% to 100%)
    'volume' => '0%',     // Speech volume (range: -100% to 100%)
    'pitch' => '0Hz'      // Voice pitch (range: -100Hz to 100Hz)
]);

// Export synthesized audio in different formats
$base64Audio = $tts->toBase64();   // Get audio as base64
$tts->toFile("output.wav");        // Save audio to file
$rawAudio = $tts->toRaw();         // Get raw audio stream

Export Options

After synthesizing speech, you can export the audio in various formats:

  • toBase64: Returns the audio as a Base64 string.
  • toFile: Saves the audio to a specified file (e.g., "output.wav").
  • toRaw: Returns the raw audio stream.

Testing

./vendor/bin/phpunit
