// Creating a client

// Usage example:
//
//   import "google.golang.org/api/texttospeech/v1"
//   ...
//   ctx := context.Background()
//   texttospeechService, err := texttospeech.NewService(ctx)

// 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:

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