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

// This package is DEPRECATED. Use package cloud.google.com/go/speech/apiv1 instead.
//
// For product documentation, see: https://cloud.google.com/speech-to-text/docs/quickstart-protocol
//
// Creating a client
//
// Usage example:
//
//   import "google.golang.org/api/speech/v1p1beta1"
//   ...
//   ctx := context.Background()
//   speechService, err := speech.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:
//
//   speechService, err := speech.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, ...)
//   speechService, err := speech.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

	//   "LINEAR16" - Uncompressed 16-bit signed little-endian samples
	// (Linear PCM).
	//   "FLAC" - `FLAC` (Free Lossless Audio Codec) is the recommended
	// encoding because it is lossless--therefore recognition is not
	// compromised--and requires only about half the bandwidth of
	// `LINEAR16`. `FLAC` stream encoding supports 16-bit and 24-bit
	// samples, however, not all fields in `STREAMINFO` are supported.
	//   "MULAW" - 8-bit samples that compand 14-bit audio samples using
	// G.711 PCMU/mu-law.
	//   "AMR" - Adaptive Multi-Rate Narrowband codec. `sample_rate_hertz`
	// must be 8000.
	//   "AMR_WB" - Adaptive Multi-Rate Wideband codec. `sample_rate_hertz`
	// must be 16000.
	//   "OGG_OPUS" - Opus encoded audio frames in Ogg container

	// be one of 8000, 12000, 16000, 24000, or 48000.
	//   "SPEEX_WITH_HEADER_BYTE" - Although the use of lossy encodings is
	// not recommended, if a very low bitrate encoding is required,
	// `OGG_OPUS` is highly preferred over Speex encoding. The
	// [Speex](https://speex.org/) encoding supported by Cloud Speech API
	// has a header byte in each block, as in MIME type
	// `audio/x-speex-with-header-byte`. It is a variant of the RTP Speex
	// encoding defined in [RFC 5574](https://tools.ietf.org/html/rfc5574).
	// The stream is a sequence of blocks, one block per RTP packet. Each
	// block starts with a byte containing the length of the block, in
	// bytes, followed by one or more frames of Speex data, padded to an
	// integral number of bytes (octets) as specified in RFC 5574. In other
	// words, each RTP header is replaced with a single byte containing the
	// block length. Only Speex wideband is supported. `sample_rate_hertz`
	// must be 16000.
	//   "MP3" - MP3 audio. MP3 encoding is a Beta feature and only
	// available in v1p1beta1. Support all standard MP3 bitrates (which

	// used.
