In depth

A closer look at Microsoft Speech SDK

Microsoft Speech SDK comprises a collection of tools, components and code examples intended to assist developers in creating applications that rely on the speech recognition technology. It allows them to build utilities that can recognize outspoken words or read texts out loud using text-to-speech engines.Speech recognition transforms voice commands into a computer control instrument, accompanying peripherals such as the mouse and the keyboard. Microsoft Speech SDK helps you meet the requirements and need of the final user with respect to human-machine interaction.The package includes assemblies, libraries, sample configurations, grammars and simulating programs intended for the development of speech-enabled applications. The extended documentation helps you learn how to take advantage of each component to create reliable and powerful software solutions.The integrated APIs help you implement speech recognition and synthesis technologies within your application, while the managed-code namespaces allow fast access to the development resources compatible with the Microsoft Speech Platform Runtime.The text-to-speech components can be used for configuring and controlling voice characteristics, such as accent, volume, fluency, word frequency or emphasis. Other tools enable you to generate grammar systems for word checking, semantics validation, phrase generation and so on.The SDK features audio recognition capabilities for multiple languages, allowing your application to record and process speech input and execute commands accordingly. It allows both semantic and literal recognition and provides support for XML documents.Microsoft Speech SDK thinks of every aspect of creating a speech recognition program, from the processing of the audio signal to identification of the semantic meaning, while also providing components for building speech synthesizers. Its powerful and reliable set of features make it a real asset, worth integrating into a developer's toolkit.
