Documentation

Building

This source code for the Cognitive Services Speeck SDK (JavaScript) is available in a public GitHub repository. You are not required to go through the build process. We create prebuilt packages tuned for your use-cases. These are updated in regular intervals.

In order to build the Speech SDK, ensure that you have Git and Node.js installed.

Clone the repository:

git clone https://github.com/Microsoft/cognitive-services-speech-sdk-js

Change to the Speech SDK directory:

cd cognitive-services-speech-sdk-js

Install the required packages:

npm install

Run the build:

npm run build

Run tests (see ci/build.yml) -- complete results require several specifically-configured subscriptions, but incomplete results can be obtained with a subset (expect and ignore failures involving missing assignments).

At a minimum, invoking npm run test will compile/lint the test files to catch early problems in test code changes.

Data / Telemetry

This project collects data and sends it to Microsoft to help monitor our service performance and improve our products and services. Read the Microsoft Privacy Statement to learn more.

To disable telemetry, you can call the following API:

// disable telemetry data
sdk.Recognizer.enableTelemetry(false);

This is a global setting and will disable telemetry for all recognizers (already created or new recognizers).

We strongly recommend you keep telemetry enabled. With telemetry enabled you transmit information about your platform (operating system and possibly, Speech Service relevant information like microphone characteristics, etc.), and information about the performance of the Speech Service (the time when you did send data and when you received data). It can be used to tune the service, monitor service performance and stability, and might help us to analyze reported problems. Without telemetry enabled, it is not possible for us to do any form of detailed analysis in case of a support request.
