Audio Generation and Transcription

Impact: MEDIUM (Text-to-speech and speech-to-text)

Generate audio from text (TTS) and transcribe audio to text (STT). Supports voice selection, instructions, diarization, storage, and queueing.

Bad Example

// Manual TTS API call — no storage, no voice control
$response = Http::withToken(config('services.openai.key'))
    ->post('https://api.openai.com/v1/audio/speech', [
        'model' => 'tts-1',
        'input' => 'Hello world',
        'voice' => 'alloy',
    ]);

file_put_contents(storage_path('audio.mp3'), $response->body());

Good Example

// Text-to-speech
use Laravel\Ai\Audio;

$audio = Audio::of('I love coding with Laravel.')->generate();
$rawContent = (string) $audio;

// Voice selection and instructions
$audio = Audio::of('I love coding with Laravel.')
    ->female()  // or ->male(), ->voice('voice-id')
    ->instructions('Said like a pirate')
    ->generate();

// Store audio
$path = $audio->store();
$path = $audio->storeAs('audio.mp3');
$path = $audio->storePublicly();

// Queue audio generation
use Laravel\Ai\Responses\AudioResponse;

Audio::of('I love coding with Laravel.')
    ->queue()
    ->then(function (AudioResponse $audio) {
        $path = $audio->store();
    });

// Speech-to-text transcription
use Laravel\Ai\Transcription;

$transcript = Transcription::fromPath('/home/laravel/audio.mp3')->generate();
$transcript = Transcription::fromStorage('audio.mp3')->generate();
$transcript = Transcription::fromUpload($request->file('audio'))->generate();

return (string) $transcript;

// Diarization — segment transcript by speaker
$transcript = Transcription::fromStorage('audio.mp3')
    ->diarize()
    ->generate();

// Queue transcription
use Laravel\Ai\Responses\TranscriptionResponse;

Transcription::fromStorage('audio.mp3')
    ->queue()
    ->then(function (TranscriptionResponse $transcript) {
        // Process transcript
    });

Why

• Fluent API: Voice, instructions, and quality in a single chain
• Multiple sources: Generate from text, transcribe from path, storage, or upload
• Diarization: Speaker-segmented transcripts for meetings and interviews
• Queueable: Offload long audio processing to background workers
• Provider support: TTS via OpenAI, ElevenLabs. STT via OpenAI, ElevenLabs, Mistral
