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 .
Example usage
To get started with this package, create a client.
ctx := context . Background () // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c , err := speech . NewClient ( ctx ) if err != nil { // TODO: Handle error. } defer c . Close ()
The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.
Using the Client
The following is an example of making an API call with the newly created client.
ctx := context . Background () // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c , err := speech . NewClient ( ctx ) if err != nil { // TODO: Handle error. } defer c . Close () req := & speechpb . RecognizeRequest { // TODO: Fill request struct fields. // See https://pkg.go.dev/cloud.google.com/go/speech/apiv1p1beta1/speechpb#RecognizeRequest. } resp , err := c . Recognize ( ctx , req ) if err != nil { // TODO: Handle error. } // TODO: Use resp. _ = resp
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.

LongRunningRecognize performs asynchronous speech recognition: receive results via the google.longrunning.Operations interface. Returns either an Operation.error or an Operation.response which contains a LongRunningRecognizeResponse message. For more information on asynchronous speech recognition, see the how-to (at https://cloud.google.com/speech-to-text/docs/async-recognize ).

CustomClassIterator manages a stream of *speechpb.CustomClass.
func (*CustomClassIterator) Next
func

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.

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

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.
