Constructor Details

#initialize {|config| ... } ⇒ Client

Examples:


# Create a client using the default configuration

client = ::Google::Cloud::Speech::V1::Speech::Rest::Client.new do |config|
  config.timeout = 10.0
end

  • (config) —

    Configure the Speech client.

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the Speech Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

Yield Parameters:

#long_running_recognize(request, options = nil) ⇒ ::Gapic::Operation #long_running_recognize(config: nil, audio: nil, output_config: nil) ⇒ ::Gapic::Operation

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.

Examples:

Basic example

require "google/cloud/speech/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Speech::V1::Speech::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Speech::V1::LongRunningRecognizeRequest.new

# Call the long_running_recognize method.
result = client.long_running_recognize request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #long_running_recognize(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to long_running_recognize via a request object, either of type LongRunningRecognizeRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Speech::V1::LongRunningRecognizeRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #long_running_recognize(config: nil, audio: nil, output_config: nil) ⇒ ::Gapic::Operation

    Pass arguments to long_running_recognize via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

#recognize(request, options = nil) ⇒ ::Google::Cloud::Speech::V1::RecognizeResponse #recognize(config: nil, audio: nil) ⇒ ::Google::Cloud::Speech::V1::RecognizeResponse

Performs synchronous speech recognition: receive results after all audio has been sent and processed.

Examples:

Basic example

require "google/cloud/speech/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Speech::V1::Speech::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Speech::V1::RecognizeRequest.new

# Call the recognize method.
result = client.recognize request

# The returned object is of type Google::Cloud::Speech::V1::RecognizeResponse.
p result

Overloads:

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
