Overview

Package speech is an auto-generated package for the Cloud Speech-to-Text API.

Converts audio to text by applying powerful neural network models. 

NOTE: This package is in beta. It is not stable, and may be subject to changes.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Types

type AdaptationCallOptions added in v1.42.0 

type AdaptationCallOptions struct {
	CreatePhraseSet   []gax.CallOption
	GetPhraseSet      []gax.CallOption
	ListPhraseSet     []gax.CallOption
	UpdatePhraseSet   []gax.CallOption
	DeletePhraseSet   []gax.CallOption
	CreateCustomClass []gax.CallOption
	GetCustomClass    []gax.CallOption
	ListCustomClasses []gax.CallOption
	UpdateCustomClass []gax.CallOption
	DeleteCustomClass []gax.CallOption
}

AdaptationCallOptions contains the retry settings for each method of AdaptationClient.

type AdaptationClient added in v1.42.0 

type AdaptationClient struct {

	// The call options for this service.
	CallOptions *AdaptationCallOptions
	// contains filtered or unexported fields
}

AdaptationClient is a client for interacting with Cloud Speech-to-Text API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Service that implements Google Cloud Speech Adaptation API.

func NewAdaptationClient added in v1.42.0 

func NewAdaptationClient(ctx context.Context, opts ...option.ClientOption) (*AdaptationClient, error)

NewAdaptationClient creates a new adaptation client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

Service that implements Google Cloud Speech Adaptation API.

Example 
package main

import (
	"context"

	speech "cloud.google.com/go/speech/apiv1p1beta1"
)

func main() {
	ctx := context.Background()
	c, err := speech.NewAdaptationClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

Output:

func (*AdaptationClient) Close added in v1.42.0 

func (c *AdaptationClient) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*AdaptationClient) Connection added in v1.42.0 

func (c *AdaptationClient) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated.

CustomClassIterator manages a stream of *speechpb.CustomClass.

func (*CustomClassIterator) Next added in v1.42.0 

func (it *CustomClassIterator) Next() (*speechpb.CustomClass, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*CustomClassIterator) PageInfo added in v1.42.0 

func (it *CustomClassIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.

type LongRunningRecognizeOperation 

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

LongRunningRecognizeOperation manages a long-running operation from LongRunningRecognize.

func (*LongRunningRecognizeOperation) Done 

func (op *LongRunningRecognizeOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*LongRunningRecognizeOperation) Metadata 

func (op *LongRunningRecognizeOperation) Metadata() (*speechpb.LongRunningRecognizeMetadata, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*LongRunningRecognizeOperation) Name 

func (op *LongRunningRecognizeOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*LongRunningRecognizeOperation) Poll 

func (op *LongRunningRecognizeOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*speechpb.LongRunningRecognizeResponse, error)

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*LongRunningRecognizeOperation) Wait 

func (op *LongRunningRecognizeOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*speechpb.LongRunningRecognizeResponse, error)

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.
