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. Use googleapi.IsNotModified to check whether the returned error was because http.StatusNotModified was returned.

                  func (*OperationsGetCall) Fields

                        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.

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

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

                                              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.

                                              func (*OperationsService) List

                                                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.

                                                      func (*ProjectsLocationsOperationsGetCall) Header

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

                                                          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.

                                                            Context sets the context to be used in this call's Do method. Any pending HTTP request will be aborted if the provided context is canceled.

                                                              Do executes the "speech.projects.locations.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 (*ProjectsLocationsOperationsService) List

                                                                                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.

It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details.
