Example 1 with SpeechClient

use of com.google.cloud.speech.spi.v1.SpeechClient in project google-cloud-java by GoogleCloudPlatform.

the class RecognizeSpeech method main.

public static void main(String... args) throws Exception {
    // Instantiates a client
    SpeechClient speech = SpeechClient.create();
    // The path to the audio file to transcribe
    // for example "./resources/audio.raw";
    String fileName = "your/speech/audio/file.raw";
    // Reads the audio file into memory
    Path path = Paths.get(fileName);
    byte[] data = Files.readAllBytes(path);
    ByteString audioBytes = ByteString.copyFrom(data);
    // Builds the sync recognize request
    RecognitionConfig config = RecognitionConfig.newBuilder().setEncoding(AudioEncoding.LINEAR16).setSampleRateHertz(16000).setLanguageCode("en-US").build();
    RecognitionAudio audio = RecognitionAudio.newBuilder().setContent(audioBytes).build();
    // Performs speech recognition on the audio file
    RecognizeResponse response = speech.recognize(config, audio);
    List<SpeechRecognitionResult> results = response.getResultsList();
    for (SpeechRecognitionResult result : results) {
        List<SpeechRecognitionAlternative> alternatives = result.getAlternativesList();
        for (SpeechRecognitionAlternative alternative : alternatives) {
            System.out.printf("Transcription: %s%n", alternative.getTranscript());
        }
    }
    speech.close();
