Summary

Expand how you interact and transact with high-performance, platform-native C++Builder and Delphi apps with the latest Embarcadero RAD Studio using CDW 2025.

More Information

CDW 2025 includes tools, libraries, samples, and documentation that illustrate how to expand C++Builder and Delphi apps with Speech Technology. This means C++Builder and Delphi apps can use your favorite speech APIs.

Develop and test C++Builder and Delphi apps with your favorite Speech Technology in three easy steps:

Install Chant Developer Workbench 2025 and Chant Developer Workbench 2025 Samples;
Add project reference to include (C++) or source (Delphi) directory;
Declare libraries and instantiate Chant objects used in app.

Credentials

To develop apps and use CDW 2025 tools, libraries, and samples, you need licensed or evaluation credentials:

Purchase licensed credentials from Chant, ComponentSource, MicroWay, or QBS; or
Request evaluation credentials via email.

Install Tools and Libraries

Install Chant Developer Workbench tools, editing, and testing surfaces by running the installer. Unlock the libraries with your credentials set under View->Options

Review steps in H032501 Installing and launching CDW 2025 tools.

Locate Libraries

Locate libraries installed with Chant Developer Workbench for all the product libraries under Program Files\Chant.

Review default locations in H032502 Installing and referencing CDW 2025 libraries.

C++Builder Apps

The basic steps to integrate libraries in C++Builder:

Add Include path reference to the header files director;
Declare libraries used in header and source;
Instantiate objects used in applications; and
Paste credentials in the code as a parameter in the SetCredentials method.

Review how fast and easy it is to enhance C++Builder apps with Chant libraries:

Audio Search: find words and phrases in recorded audio
GrammarKit: dynamically adjust and compile grammar syntax
KinesicsKit: capture images and audio from Kinect sensors
LexiconKit: adjust pronunciations for better speech synthesis and recognition
ProfileKit: administrate user properties
SpeechKit: recognize and synthesize speech
Speech Manager: manage speech synthesis and recognition requests queue
Talk&Listen: invoke simple speech recognition or synthesis request
VoiceMarkupKit: dynamically generate API-specific SSML for fine-tuned speech synthesis
VoiceXMLKit: validate and test VoiceXML

Delphi Apps

The basic steps to integrate libraries in Delphi are:

Add Search path reference to the source file directory;
Declare libraries used in Uses statement;
Instantiate objects used in applications; and
Paste credentials in the code as a parameter in the SetCredentials method.
