// Package texttospeech provides access to the Cloud Text-to-Speech API.

// For product documentation, see: https://cloud.google.com/text-to-speech/
//
// # Creating a client
//
// Usage example:
//
//	import "google.golang.org/api/texttospeech/v1beta1"
//	...
//	ctx := context.Background()
//	texttospeechService, err := texttospeech.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for authentication.
//
// For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.
//
// # 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)))
