Chant ProfileKit

Maximize speech recognition accuracy by ensuring end users have completed training sessions with the recognizer. Speaker training—even for command and grammar-based recognition—is essential for accuracy.

A recognition profile is a collection of information used by a speech recognition engine to increase its recognition accuracy for a specific individual’s voice and environment.

A speech recognition engine saves training and background noise information to use in recognizing speech. Some speech recognition engines, such as Microsoft’s Recognizer, capture and save information over time to adapt the profile for optimum speech recognition accuracy.

What is Profile Management?

Profile management enables you to:

  • create speech recognition profiles,
  • delete speech recognition profiles, and
  • train speech recognition profiles.

Applications benefits include:

  • enhanced speech recognition accuracy,
  • added flexibility to adapt to different acoustical environments, and
  • expanded reliability to recover from system errors.

What is ProfileKit?

Chant ProfileKit handles the complexities of managing profiles.

It simplifies the process of managing profiles for Microsoft SAPI 5, Microsoft Speech Platform, and Nuance Dragon NaturallySpeaking recognizers. You can create, delete, and train profiles as needed within your application.

ProfileKit includes C++, C++Builder, Delphi, Java, and .NET Framework class library formats to support all your programming languages and sample projects for popular IDEs—such as the latest Visual Studio from Microsoft, RAD Studio from Embarcadero, and Java IDEs Eclipse, IntelliJ, JDeveloper, and NetBeans.

The class libraries can be integrated with 32-bit and 64-bit applications for Windows platforms.

Profile Management Architecture

ProfileKit provides a simple way to create, delete, and train speaker profiles. Applications integrate speaker profile training as part of its speech recognition administrative features.

Applications can select or create a speaker profile, train it, and delete a speaker profile. ProfileKit supports the following speech APIs for profile management:

Applications receive training notifications through event callbacks.

ProfileKit Architecture for Profile Management

ProfileKit encapsulates all of the technologies necessary to make the process of managing profiles simple and efficient.

ProfileKit simplifies the process of managing profiles by handling the low-level activities directly with the speech application program interface (API).

Instantiate ProfileKit to manage a speaker profile and destroy ProfileKit to release its resources when speaker profile management is no longer needed.

Feature Summary

The goal of profile management is to maximize speech recognition accuracy. With ProfileKit you can:

  • Detect audio sweet spot;
  • Create and delete speaker profiles on demand;
  • Launch recognizer built-in dialogs; and
  • Customize speaker training.

Chant ProfileKit handles the complexities of working with speaker profiles. This allows your application to enhance the quality of speech recognition and offer administrative features for maintaining speaker profiles.

Recognizers provide speaker training via built-in dialogs and/or custom training via API calls. ProfileKit supports the following recognizers and speaker training options:
