Documentation

Overview

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/v1"
...
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)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

Do executes the "speech.operations.get" call. Exactly one of *Operation or error will be non-nil. Any non-2xx status code is an error. Response headers are in either *Operation.ServerResponse.Header or (if a response was returned at all) in error.(*googleapi.Error).Header.

func (*OperationsGetCall) IfNoneMatch 

func (c *OperationsGetCall) IfNoneMatch(entityTag string) *OperationsGetCall

IfNoneMatch sets the optional parameter which makes the operation fail if the object's ETag matches the given value. This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

type OperationsListCall 

type OperationsListCall struct {
	// contains filtered or unexported fields
}

func (*OperationsListCall) Context

func (*OperationsListCall) Do 

func (c *OperationsListCall) Do(opts ...googleapi.CallOption) (*ListOperationsResponse, error)

Do executes the "speech.operations.list" call. Exactly one of *ListOperationsResponse or error will be non-nil. Any non-2xx status code is an error. Response headers are in either *ListOperationsResponse.ServerResponse.Header or (if a response was returned at all) in error.(*googleapi.Error).Header. Use googleapi.IsNotModified to check whether the returned error was because http.StatusNotModified was returned.

func (*OperationsListCall) Fields 

func (c *OperationsListCall) Fields(s ...googleapi.Field) *OperationsListCall

Fields allows partial responses to be retrieved. See https://developers.google.com/gdata/docs/2.0/basics#PartialResponse for more information.

func (*OperationsListCall) Filter 

func (c *OperationsListCall) Filter(filter string) *OperationsListCall

Filter sets the optional parameter "filter": The standard list filter.

func (*OperationsListCall) Header 

func (c *OperationsListCall) Header() http.Header

Header returns an http.Header that can be modified by the caller to add HTTP headers to the request.

func (*OperationsListCall) IfNoneMatch 

func (c *OperationsListCall) IfNoneMatch(entityTag string) *OperationsListCall

IfNoneMatch sets the optional parameter which makes the operation fail if the object's ETag matches the given value. This is useful for getting updates only after the object has changed since the last request. Use googleapi.IsNotModified to check whether the response error from Do is the result of In-None-Match.

func (*OperationsListCall) Name 

func (c *OperationsListCall) Name(name string) *OperationsListCall

Name sets the optional parameter "name": The name of the operation's parent resource.

PageToken sets the optional parameter "pageToken": The standard list page token.

func (*OperationsListCall) Pages 

func (c *OperationsListCall) Pages(ctx context.Context, f func(*ListOperationsResponse) error) error

Pages invokes f for each page of results. A non-nil error returned from f will halt the iteration. The provided context supersedes any context provided to the Context method.

type OperationsService

	// contains filtered or unexported fields
}

func NewOperationsService 

func NewOperationsService(s *Service) *OperationsService

func (*OperationsService) Get 

func (r *OperationsService) Get(name string) *OperationsGetCall

Get: Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.

- name: The name of the operation resource.

func (*OperationsService) List 

func (r *OperationsService) List() *OperationsListCall

List: Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns `UNIMPLEMENTED`. NOTE: the `name` binding allows API services to override the binding to use different resource name schemes, such as `users/*/operations`. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

type RecognitionAudio

	// (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
