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/v2beta1" ... 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.

// contains filtered or unexported fields
}
func (*ProjectsLocationsOperationsGetCall) Context ¶
func (c *ProjectsLocationsOperationsGetCall) Context(ctx context.Context) *ProjectsLocationsOperationsGetCall
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.
func (*ProjectsLocationsOperationsGetCall) Do ¶
func (c *ProjectsLocationsOperationsGetCall) Do(opts ...googleapi.CallOption) (*Operation, error)
Do executes the "speech.projects.locations.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 (*ProjectsLocationsOperationsGetCall) Fields ¶
func (c *ProjectsLocationsOperationsGetCall) Fields(s ...googleapi.Field) *ProjectsLocationsOperationsGetCall
Fields allows partial responses to be retrieved. See https://developers.google.com/gdata/docs/2.0/basics#PartialResponse for more information.

func (c *ProjectsLocationsOperationsGetCall) Header() http.Header
Header returns an http.Header that can be modified by the caller to add HTTP headers to the request.
func (*ProjectsLocationsOperationsGetCall) IfNoneMatch ¶
func (c *ProjectsLocationsOperationsGetCall) IfNoneMatch(entityTag string) *ProjectsLocationsOperationsGetCall
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 ProjectsLocationsOperationsListCall ¶
type ProjectsLocationsOperationsListCall struct {
// contains filtered or unexported fields
}
func (*ProjectsLocationsOperationsListCall) Context ¶
func (c *ProjectsLocationsOperationsListCall) Context(ctx context.Context) *ProjectsLocationsOperationsListCall
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.
func (*ProjectsLocationsOperationsListCall) Do ¶
func (c *ProjectsLocationsOperationsListCall) Do(opts ...googleapi.CallOption) (*ListOperationsResponse, error)
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 (*ProjectsLocationsOperationsListCall) Fields ¶
func (c *ProjectsLocationsOperationsListCall) Fields(s ...googleapi.Field) *ProjectsLocationsOperationsListCall
Fields allows partial responses to be retrieved. See https://developers.google.com/gdata/docs/2.0/basics#PartialResponse for more information.
func (*ProjectsLocationsOperationsListCall) Filter ¶
func (c *ProjectsLocationsOperationsListCall) Filter(filter string) *ProjectsLocationsOperationsListCall
Filter sets the optional parameter "filter": The standard list filter.
func (*ProjectsLocationsOperationsListCall) Header ¶
func (c *ProjectsLocationsOperationsListCall) Header() http.Header
Header returns an http.Header that can be modified by the caller to add HTTP headers to the request.
func (*ProjectsLocationsOperationsListCall) IfNoneMatch ¶
func (c *ProjectsLocationsOperationsListCall) IfNoneMatch(entityTag string) *ProjectsLocationsOperationsListCall
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 (*ProjectsLocationsOperationsListCall) PageSize ¶
func (c *ProjectsLocationsOperationsListCall) PageSize(pageSize int64) *ProjectsLocationsOperationsListCall
PageSize sets the optional parameter "pageSize": The standard list page size.
func (*ProjectsLocationsOperationsListCall) PageToken ¶
func (c *ProjectsLocationsOperationsListCall) PageToken(pageToken string) *ProjectsLocationsOperationsListCall
PageToken sets the optional parameter "pageToken": The standard list page token.
func (*ProjectsLocationsOperationsListCall) Pages ¶
func (c *ProjectsLocationsOperationsListCall) 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 ProjectsLocationsOperationsService ¶
type ProjectsLocationsOperationsService struct {
// contains filtered or unexported fields
}
func NewProjectsLocationsOperationsService ¶
func NewProjectsLocationsOperationsService(s *Service) *ProjectsLocationsOperationsService
func (*ProjectsLocationsOperationsService) Get ¶
func (r *ProjectsLocationsOperationsService) Get(name string) *ProjectsLocationsOperationsGetCall
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 (*ProjectsLocationsOperationsService) List ¶
func (r *ProjectsLocationsOperationsService) List(name string) *ProjectsLocationsOperationsListCall
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.
- name: The name of the operation's parent resource.

Status: The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC (https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the API Design Guide (https://cloud.google.com/apis/design/errors).
