Installing the Microsoft Speech Platform SDK 11

To install the Microsoft Speech Platform SDK 11

  1. Uninstall any previous version of the Speech Platform SDK and the Microsoft Speech Platform Runtime from your computer.

  2. Verify that you have installed the Microsoft .NET Framework version 4.0. If necessary, download the .NET Framework 4.0 using this link. The .NET Framework must be installed before you install the Speech Platform Runtime 11 and the Speech Platform SDK 11.

  3. Determine whether you are using a 32-bit or 64-bit operating system.

  4. Download the Speech Platform Runtime 11 that matches your operating system using this link.

  5. Download the Speech Platform SDK 11 that matches your operating system using this link.

Important

The Speech Platform Runtime 11 and the Speech Platform SDK 11 do not include Runtime Languages for speech recognition or for speech synthesis (TTS or text-to-speech). You must install them separately. A Runtime Language includes the language model, acoustic model, and other data necessary to provision a speech engine to perform speech recognition or TTS in a particular language. There are separate Runtime Languages for speech recognition or speech synthesis. The version of Runtime Languages that you download (for example, version 11.0) must match the version of the Speech Platform Runtime that you have installed. You can download Runtime Languages using this link.
