Getting Started With Microsoft Cognitive Services - Bing Speech API


In this article, we will learn how to get started with Microsoft Azure Cognitive Services – Bing Speech API.


This is in continuation of my articles with respect to Cognitive Services. I have come across some complicated articles on Cognitive Services, but as I've been working on this service for the last eight months, I thought of writing simple, step by step articles with respect to Cognitive Services.

If you have landed directly on this article, I would recommend you to read the following -

As defined, Cognitive Services provide the best suite for having interactive, automated models of application. It helps to build powerful intelligence into applications to enable natural and contextual interactions.

Bing Speech API, as described by Microsoft, enables speech capabilities on all internet-connected devices. Every major platform including Android, iOS, Windows, and 3rd party IoT devices are supported. It offers industry-leading speech-to-text, text-to-speech, and language understanding capabilities delivered through the cloud.

Microsoft uses Bing Speech API for Windows applications, like Cortana and Skype Translator as well as Android applications, like Bing Torque for Android Wear and Android Phone.

It offers,

  • Speech recognition

    • Converts spoken audio to text in real time irrespective of any audio source.
    • Supports real-time streaming.

  • Speech intent recognition

    • Converts spoken audio to intent that drives actions as programmed.
    • Using LUIS models it parses the intent of the speaker to create actions within the application.

  • Text to speech conversion

    • Converts provided text to spoken audio.
    • It plays an important role when applications need to “talk” to / back to their users.
      Will learn more about Bing Speech APIs in later articles. To start with, let's create cognitive account to Bing Speech using Azure Portal.
