                option.WithEndpoint(fakeServerAddr),
                option.WithoutAuthentication(),
                option.WithGRPCDialOption(grpc.WithInsecure()),
        )
        if err != nil {
                t.Fatal(err)
        }

        // Run the test.
        text, err := TranslateTextWithConcreteClient(client, "Hola Mundo", "en-US")
        if err != nil {
                t.Fatal(err)
        }

	server := pstest.NewServer(nil)
	defer server.Close()

	// The server's endpoint can be used to configure clients.
	serverEndpoint := server.Addr

	// Example: Configure a Pub/Sub client to use the fake server.
	// (Actual client creation would involve `pubsub.NewClient` with appropriate options pointing to `serverEndpoint`)

	// You can create topics and subscriptions on the fake server.
	topicName := "my-test-topic-" + uuid.New().String()
	t_	, err := server.CreateTopic(ctx, topicName)
	if err != nil {
		panic(err)
	}

	subName := "my-test-subscription-" + uuid.New().String()

func main() {
	ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
	defer cancel()

	// Stream audio for 5 seconds
	audioStream := goEagi.StreamAudio(ctx)
	var audioBuffer []byte

	for {
		select {
		case <-ctx.Done():
			// Generate WAV file from collected audio
			audioPath, err := goEagi.GenerateAudio(
				audioBuffer,
				"/tmp/recordings/",
				"call_recording.wav",
			)
			if err != nil {
				fmt.Printf("Error generating audio: %v\n", err)
