Installation

Laravel Auto-Discovery

The package will automatically register itself with Laravel's package auto-discovery feature.

Manual Registration (if needed)

If auto-discovery is disabled, manually add the service provider to your config/app.php:

'providers' => [
    // Other providers...
    NextBuild\SarvamAI\SarvamAIServiceProvider::class,
],

'aliases' => [
    // Other aliases...
    'SarvamAI' => NextBuild\SarvamAI\Facades\SarvamAI::class,
],

Configuration

Publish the configuration file:

php artisan vendor:publish --tag=sarvam-ai-config

Add your Sarvam AI API key to your .env file:

SARVAM_AI_API_KEY=your-api-key-here

Usage

Using the Facade

use NextBuild\SarvamAI\Facades\SarvamAI;

// Speech to Text
$response = SarvamAI::speechToText('/path/to/audio/file.wav', 'saarika:v1', 'hi-IN');
$transcript = $response->getTranscript();

// Text to Speech
$response = SarvamAI::textToSpeech('Hello world', 'en-IN');
$audioUrl = $response->getAudioUrl();

// Translation
$response = SarvamAI::translateText('Hello world', 'en-IN', 'hi-IN');
$translatedText = $response->getTranslatedText();

// Chat Completions
$messages = [
    ['role' => 'user', 'content' => 'Hello, how are you?']
];
$response = SarvamAI::chatCompletions($messages);
$reply = $response->getChatCompletionContent();

Using Dependency Injection

use NextBuild\SarvamAI\SarvamAI;

class YourController extends Controller
{
    protected $sarvamAI;

    public function __construct(SarvamAI $sarvamAI)
    {
        $this->sarvamAI = $sarvamAI;
    }

    public function translateText(Request $request)
    {
        $response = $this->sarvamAI->translateText(
            $request->input('text'),
            $request->input('source_language', 'auto'),
            $request->input('target_language', 'en-IN')
        );

        return response()->json([
            'translated_text' => $response->getTranslatedText(),
            'original_data' => $response->getData()
        ]);
    }
}

API Methods

Speech to Text

Convert audio files to text:

$response = SarvamAI::speechToText('/path/to/audio/file.wav');
$transcript = $response->getTranscript();

Speech to Text with Translation

Convert audio to text with automatic translation:

$response = SarvamAI::speechToTextTranslate('/path/to/audio/file.wav', null, 'saarika:v1');
$transcript = $response->getTranscript();

Text to Speech

Generate audio from text:

$response = SarvamAI::textToSpeech('Hello world', 'en-IN');
$audioUrl = $response->getAudioUrl();

Text Translation

Translate text between languages:

$response = SarvamAI::translateText('Hello world', 'en-IN', 'hi-IN');
$translatedText = $response->getTranslatedText();

Language Identification

Detect the language of text:

$response = SarvamAI::identifyLanguage('Hello world');
$detectedLanguage = $response->getDetectedLanguage();

Text Transliteration

Convert text between scripts:

$response = SarvamAI::transliterateText('Hello world', 'en-IN', 'hi-IN');
$transliteratedText = $response->getTransliteratedText();

Chat Completions

AI-powered chat responses:

$messages = [
    ['role' => 'user', 'content' => 'What is the capital of India?']
];
$response = SarvamAI::chatCompletions($messages, 'sarvam-m');
$reply = $response->getChatCompletionContent();

Response Handling

All methods return a SarvamAIResponse object with the following methods:

$response = SarvamAI::translateText('Hello', 'en-IN', 'hi-IN');

// Get specific data
$translatedText = $response->getTranslatedText();
$statusCode = $response->getStatusCode();
$headers = $response->getHeaders();

// Get raw data
$data = $response->getData();
$body = $response->getBody();

// Convert to array or JSON
$array = $response->toArray();
$json = $response->toJson();

// Check if successful
$isSuccessful = $response->isSuccessful();

Error Handling

The package throws SarvamAIException for API errors:

use NextBuild\SarvamAI\Exceptions\SarvamAIException;

try {
    $response = SarvamAI::translateText('Hello world', 'en-IN', 'hi-IN');
    $translatedText = $response->getTranslatedText();
} catch (SarvamAIException $e) {
    // Handle the error
    Log::error('Sarvam AI Error: ' . $e->getMessage());
    return response()->json(['error' => 'Translation failed'], 500);
}

Configuration Options

The configuration file includes the following options:

return [
    'api_key' => env('SARVAM_AI_API_KEY'),
    'default_source_language' => env('SARVAM_AI_DEFAULT_SOURCE_LANGUAGE', 'auto'),
    'default_target_language' => env('SARVAM_AI_DEFAULT_TARGET_LANGUAGE', 'en-IN'),
    'timeout' => env('SARVAM_AI_TIMEOUT', 30),
    'retry' => env('SARVAM_AI_RETRY', 3),
    'chat' => [
        'default_model' => env('SARVAM_AI_DEFAULT_MODEL', 'sarvam-m'),
        'max_tokens' => env('SARVAM_AI_MAX_TOKENS=1000
SARVAM_AI_TEMPERATURE=0.7

Advanced Usage

Custom API Key

You can set a custom API key at runtime:

SarvamAI::setApiKey('your-custom-api-key')->translateText('Hello', 'en-IN', 'hi-IN');

Custom Timeout

Set a custom timeout for requests:

SarvamAI::setTimeout(60)->speechToText('/path/to/long/audio/file.wav');

Chaining Methods

You can chain configuration methods:

$response = SarvamAI::setApiKey('custom-key')
    ->setTimeout(60)
    ->translateText('Hello world', 'en-IN', 'hi-IN');

Working with Files

For speech-to-text operations, ensure your audio files are in supported formats:

// Supported formats: WAV, MP3, FLAC, etc.
$audioFile = storage_path('app/audio/sample.wav');
$response = SarvamAI::speechToText($audioFile);

if ($response->isSuccessful()) {
    $transcript = $response->getTranscript();
    // Process the transcript
}

Testing

The package includes comprehensive tests. Run them with:

composer test

For test coverage:

composer test-coverage
