// # Creating a client

// Usage example:
//
//	import "google.golang.org/api/texttospeech/v1beta1"
//	...
//	ctx := context.Background()
//	texttospeechService, err := texttospeech.NewService(ctx)
//

// # Other authentication options

// To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:
//
//	texttospeechService, err := texttospeech.NewService(ctx, option.WithAPIKey("AIza..."))

// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:
//
//	config := &oauth2.Config{...}

//	token, err := config.Exchange(ctx, ...)
//	texttospeechService, err := texttospeech.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
