SpeechKit

What is Speech Management?

Speech management enables you to:

• control application functions by speaking rather than having to use a mouse or keyboard,
• capture data by speaking rather than typing, and
• prompt and confirm data capture with spoken or audio acknowledgement.

Applications benefits include:

• enhanced speed and accuracy of data capture,
• added flexibility of running applications in a variety of environments, and
• expanded operating scenarios for hands-free computing.

What is SpeechKit?

Chant SpeechKit handles the complexities of speech recognition and speech synthesis to minimise the programming necessary to develop software that speaks and listens.

It simplifies the process of managing Apple Speech, Google android.speech, Microsoft SAPI 5, Microsoft Speech Platform, Microsoft WindowsMedia (UWP and WinRT), and Nuance Dragon NaturallySpeaking recognizers, and managing Acapela, Apple AVFoundation, Cepstral, CereProc, Google android.speech.tts, Microsoft SAPI 5, Microsoft Speech Platform, and Microsoft WindowsMedia (UWP and WinRT) synthesizers.

SpeechKit includes Android, C++, C++Builder, Delphi, Java,.NET Framework, Objective-C (iOS and macOS), and Swift (iOS and macOS) class libraries to support all your programming languages and sample projects for popular IDEs—such as the latest Visual Studio from Microsoft, RAD Studio from Embarcadero, Android Studio from Google, and Xcode from Apple.

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

Speech Recognition and Synthesis Architecture

SpeechKit provides a productive way to develop software that listens. Applications set properties and invokes methods through a speech recognition management class. This class handles the low-level functions with speech recognition engines (i.e., recognizers).

Applications establish a session with a recognizer through which spoken language captured live via a microphone or from recorded audio is processed and converted to text. Applications use SpeechKit to manage the activities for speech recognition on their behalf. SpeechKit manages the resources and interacts directly with the speech application program interface (API). SpeechKit supports the following speech APIs for speech recognition:

• Apple Speech,
• Google android.speech,
• Microsoft SAPI 5,
• Microsoft Speech Platform,
• Microsoft System.Speech,
• Microsoft Microsoft.Speech,
• Microsoft WindowsMedia, and
• Nuance Dragon NaturallySpeaking.

Applications receive recognised speech as text and notification of other processing states through event callbacks.

SpeechKit Architecture for Speech Recognition

SpeechKit encapsulates all of the technologies necessary to make the process of recognizing speech simple and efficient for applications.

Speech Synthesis Management

SpeechKit provides a productive way to develop software that speaks. Applications set properties and invoke methods through the speech synthesis management class. This class handles the low-level functions with text-to-speech engines (i.e., synthesizers or voices).

Applications establish a session with a synthesizer through which speech is synthesized from text. Applications use SpeechKit to manage the synthesizer resources on their behalf. SpeechKit manages the resources and interacts directly with a speech application program interface (API). SpeechKit supports the following speech APIs for speech synthesis:

• Acapela TTS,
• Apple AVFoundation,
• Cepstral Swift,
• CereProc CereVoice,
• Google android.speech.tts,
• Microsoft SAPI 5,
• Microsoft Speech Platform,
• Microsoft System.Speech,
• Microsoft Microsoft.Speech, and
• Microsoft WindowsMedia.

Application receive notification of other processing states through event callbacks.

SpeechKit Architecture for Speech Synthesis

The ChantTTS class encapsulates all of the technologies necessary to make the process of synthesizing speech simple for your application. Optionally, it can save the session properties for your application to ensure they persist across application invocations.

SpeechKit simplifies the process of synthesizing speech by handling the low-level activities directly with a synthesizer.

Instantiate SpeechKit to synthesize speech within the application and destroy SpeechKit to release its resources when speech synthesis is no longer needed.

Feature Summary

Chant SpeechKit handles the complexities of speech recognition and speech synthesis. The classes minimise the programming efforts necessary to construct software that speaks and listens.

A SpeechKit application can:

• Control application functions by speaking rather than having to use a mouse or keyboard;
• Prompt users for applicable data capture;
• Capture data by speaking rather than typing;
• Confirm data capture with spoken or audio acknowledgement;
• Transcribe audio buffers, files, and streams to text; and
• Synthesize speech to audio buffers, files, and streams.

Recognizers provide proprietary programming interfaces (i.e., APIs). SpeechKit supports the following recognizers and their APIs:

Synthesizers are accessed via proprietary application programming interfaces (APIs). SpeechKit supports the following speech APIs for speech synthesis:

Within Chant Developer Workbench, you can:

• Enumerate speech engines for testing recognizer-, and synthesizer-specific features;
• Trace recognition and synthesis events;
• Support grammar activation and testing; and
• Support TTS markup playback.

Recognizer Management:Enumerate and test recognizers with command, dictation, and grammar vocabularies.

Synthesizer Management: Enumerate and test synthesizers. Use the Speech Synthesis window to synthesize text. Trace synthesis events in the Events window.
