Java Console app for the Java Run-Time Environment (JRE) on Windows or Linux (Ubuntu 16.04, Ubuntu 18.04, Debian 9)

This sample demonstrates various forms of speech recognition, intent recognition, and translation using the Speech SDK for Java on Windows or Linux.

Note: the Speech SDK for the JRE currently supports only the Windows x64 platform and Linux (Ubuntu 16.04 x64, Ubuntu 18.04 x64, Debian 9 x64).

Prerequisites

  • A subscription key for the Speech service. See Try the speech service for free.

  • A PC (Windows x64, Ubuntu 16.04 or 18.04 x64) capable to run Eclipse, some sample scenarios require a working microphone.

  • 64-bit JRE/JDK for Java 8.

  • Version 4.8 of Eclipse, 64-bit.

  • On Ubuntu, run the following commands for the installation of required packages:

    sudo apt-get update
sudo apt-get install libssl1.0.0 libasound2

  • On Debian 9, run the following commands for the installation of required packages:

    sudo apt-get update
sudo apt-get install libssl1.0.2 libasound2

Build the sample

  • By building this sample you will download the Microsoft Cognitive Services Speech SDK. By downloading you acknowledge its license, see Speech SDK license agreement.

  • Download the sample code to your development PC.

  • Create an empty workspace in Eclipse and import the folder containing this sample as a project into your workspace.

  • To tailor the sample to your environment, use search and replace across the whole project to update the following strings:

    • YourSubscriptionKey: replace with your subscription key.
    • YourServiceRegion: replace with the region your subscription is associated with. For example, westus or northeurope.
    • YourEndpointId (optional): replace with the endpoint ID of your customized model in CRIS.
    • YourAudioFile.wav: replace with a path to a .wav file on your disk (required format: 16 kHz sample rate, 16 bit samples, mono / single-channel)
    • The following settings apply for intent recognition powered by the Language Understanding service (LUIS):
      • YourLanguageUnderstandingSubscriptionKey: replace with your Language Understanding service subscription key (endpoint key).
      • YourLanguageUnderstandingServiceRegion: replace with the region associated with your Language Understanding service subscription.
      • YourLanguageUnderstandingAppId: replace with the ID of a Language Understanding service application that you want to recognize intents with.
      • YourLanguageUnderstandingIntentName1, YourLanguageUnderstandingIntentName2, YourLanguageUnderstandingIntentName3: replace with names of intents that your Language Understanding service application recognizes.
    • The following settings apply to keyword-triggered recognition:
      • YourKeywordRecognitionModelFile.table: replace with the location of your keyword recognition model file.
      • YourKeyword: replace with the phrase your keyword recognition model triggers on.

  • Save the modified files.
