Package com.google.cloud.speech.v1 (4.23.0)

A client to Cloud Speech-to-Text API

The interfaces provided are listed below, along with usage samples.

SpeechClient

Service Description: Service that implements Google Cloud Speech API.

Sample for SpeechClient:


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (SpeechClient speechClient = SpeechClient.create()) {
   RecognitionConfig config = RecognitionConfig.newBuilder().build();
   RecognitionAudio audio = RecognitionAudio.newBuilder().build();
   RecognizeResponse response = speechClient.recognize(config, audio);
 }

AdaptationClient

Service Description: Service that implements Google Cloud Speech Adaptation API.

Sample for AdaptationClient:


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (AdaptationClient adaptationClient = AdaptationClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   PhraseSet phraseSet = PhraseSet.newBuilder().build();
   String phraseSetId = "phraseSetId959902180";
   PhraseSet response = adaptationClient.createPhraseSet(parent, phraseSet, phraseSetId);
 }

Classes

AdaptationClient

Service Description: Service that implements Google Cloud Speech Adaptation API.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (AdaptationClient adaptationClient = AdaptationClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   PhraseSet phraseSet = PhraseSet.newBuilder().build();
   String phraseSetId = "phraseSetId959902180";
   PhraseSet response = adaptationClient.createPhraseSet(parent, phraseSet, phraseSetId);
 }

Note: close() needs to be called on the AdaptationClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of AdaptationSettings to create(). For example:

To customize credentials:


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 AdaptationSettings adaptationSettings =
     AdaptationSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 AdaptationClient adaptationClient = AdaptationClient.create(adaptationSettings);

To customize the endpoint:


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 AdaptationSettings adaptationSettings =
     AdaptationSettings.newBuilder().setEndpoint(myEndpoint).build();
 AdaptationClient adaptationClient = AdaptationClient.create(adaptationSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // 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://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 AdaptationSettings adaptationSettings = AdaptationSettings.newHttpJsonBuilder().build();
 AdaptationClient adaptationClient = AdaptationClient.create(adaptationSettings);

A phrases containing words and phrase "hints" so that the speech recognition is more likely to recognize them. This can be used to improve the accuracy for specific words and phrases, for example, if specific commands are typically spoken by the user. This can also be used to add additional words to the vocabulary of the recognizer. See usage limits.

List items can also include pre-built or custom classes containing groups of words that represent common concepts that occur in natural language. For example, rather than providing a phrase hint for every month of the year (e.g. "i was born in january", "i was born in febuary", ...), use the pre-built $MONTH class improves the likelihood of correctly transcribing audio that includes months (e.g. "i was born in $month"). To refer to pre-built classes, use the class' symbol prepended with $ e.g. $MONTH. To refer to custom classes that were defined inline in the request, set the class's custom_class_id to a string unique to all class resources and inline classes. Then use the class' id wrapped in ${...} e.g. "${my-months}". To refer to custom classes resources, use the class' id wrapped in ${} (e.g. ${my-months}).

Speech-to-Text supports three locations: global, us (US North America), and eu (Europe). If you are calling the speech.googleapis.com endpoint, use the global location. To specify a region, use a regional endpoint with matching us or eu location value.

StreamingRecognizeResponse

StreamingRecognizeResponse is the only message returned to the client by StreamingRecognize. A series of zero or more StreamingRecognizeResponse messages are streamed back to the client. If there is no recognizable audio, and single_utterance is set to false, then no messages are streamed back to the client.

Here's an example of a series of StreamingRecognizeResponses that might be returned while processing audio:

results { alternatives { transcript: "tube" } stability: 0.01 }
results { alternatives { transcript: "to be a" } stability: 0.01 }
results { alternatives { transcript: "to be" } stability: 0.9 } results { alternatives { transcript: " or not to be" } stability: 0.01 }
results { alternatives { transcript: "to be or not to be" confidence: 0.92 } alternatives { transcript: "to bee or not to bee" } is_final: true }
results { alternatives { transcript: " that's" } stability: 0.01 }
results { alternatives { transcript: " that is" } stability: 0.9 } results { alternatives { transcript: " the question" } stability: 0.01 }
results { alternatives { transcript: " that is the question" confidence: 0.98 } alternatives { transcript: " that was the question" } is_final: true }

Notes:
Only two of the above responses #4 and #7 contain final results; they are indicated by is_final: true. Concatenating these together generates the full transcript: "to be or not to be that is the question".
The others contain interim results. #3 and #6 contain two interim results: the first portion has a high stability and is less likely to change; the second portion has a low stability and is very likely to change. A UI designer might choose to show only high stability results.
The specific stability and confidence values shown above are only for illustrative purposes. Actual values may vary.
In each response, only one of these fields will be set: error, speech_event_type, or one or more (repeated) results.

Enums

RecognitionAudio.AudioSourceCase

RecognitionConfig.AudioEncoding

The encoding of the audio data sent in the request.

All encodings support only 1 channel (mono) audio, unless the audio_channel_count and enable_separate_recognition_per_channel fields are set.

For best results, the audio source should be captured and transmitted using a lossless encoding (FLAC or LINEAR16). The accuracy of the speech recognition can be reduced if lossy codecs are used to capture or transmit audio, particularly if background noise is present. Lossy codecs include MULAW, AMR, AMR_WB, OGG_OPUS, SPEEX_WITH_HEADER_BYTE, MP3, and WEBM_OPUS.

The FLAC and WAV audio file formats include a header that describes the included audio content. You can request recognition for WAV files that contain either LINEAR16 or MULAW encoded audio. If you send FLAC or WAV audio file format in your request, you do not need to specify an AudioEncoding; the audio encoding format is determined from the file header. If you specify an AudioEncoding when you send send FLAC or WAV audio, the encoding configuration must match the encoding described in the audio header; otherwise the request returns an google.rpc.Code.INVALID_ARGUMENT error code.
