Text-To-Speech Package for Laravel

This is a Text-To-Speech package for Laravel. Its primary intention is to use a shared API to easily convert text to speech.

Currently, the only supported driver is Amazon Polly. We are exploring the option to soon support Google WaveNet. Feel free to start a discussion on any possible driver.

💡 Usage

use Cion\TextToSpeech\Facades\TextToSpeech;

// convert text from a text file
$path = TextToSpeech::source('path')
    ->convert('/path/to/text/file');

// you may also pass the string directly to convert() method
$path = TextToSpeech::convert('Convert this string.');

// configure where to save the converted output. In this case, it would save the output file in the storage/output.mp3
$path = TextToSpeech::saveTo('output.mp3')
    ->convert('Hi this is a test.');

// store the converted output directly to S3
$path = TextToSpeech::disk('s3')
    ->saveTo('output.mp3')
    ->convert('Store me to S3.');

// convert website articles & blog posts to an audio file
$path = TextToSpeech::source('website')
    ->convert('https://medium.com/cloud-academy-inc/an-introduction-to-aws-polly-s3-and-php-479490bffcbd');

/**
 * Change the language to be used for the conversion.
 * Note: every language has a specific voice_id.
 * For example in ja-JP language we need to use either Mizuki or Takumi.
 *
 * We can pass an option array in convert to change the voice_id to be used
 **/
$options = ['voice' => 'Takumi'];
$path = TextToSpeech::language('ja-JP')
    ->convert('これはテストです', $options);

// use the SSML text type in the convert() method.
$path = TextToSpeech::ssml()
    ->convert('<speak>Hi There <break /> This is SSML syntax</speak');

// using speech marks.
$output = TextToSpeech::speechMarks(['sentence', 'word', 'viseme', 'ssml'])
    ->convert('This is a test'); // This will return an array.
