The Voice control manager API provides functions for recording voice and giving responses for recognized voice commands to users.

Required Header

#include <voice_control_manager.h>

Overview

A main function of Voice Control Manager API records voice and gives responses for recognized voice commands. A Voice Control Manager application can start recording user's utterance and get responses from Voice Control engine service. The responses are dependent on the Voice Control engine service. For example, the engine service may send ASR(Automatic Speech Recognition) results or NLU(Natural Language Understanding) results. Also, it may send plural results. Therefore, the application can get various recognition results from the engine service and handle them by showing responses to users or controlling Voice Control applications. Like this, the Voice Control Manager application takes a role of controlling Voice Control applications. For this reason, developers who have an authority granted by Tizen platform can make the Voice Control Manager application.

To use of Voice Control Manager, use the following steps:
1. Initialize
2. Register callback functions for notifications
3. Connect to voice control service asynchronously. The state should be changed to Ready
4. Make command list as the following step and Step 4 is called repeatedly for each command which an application wants
4-1. Create command list handle
4-2. Create command handle
4-3. Set command and type for command handle
4-4. Add command handle to command list
5. Set command list for recognition
6. Get recognition results
7. Request the dialogue
8. If an application wants to finish voice control,
8-1. Destroy command and command list handle
8-2. Deinitialize
An application can obtain command handle from command list, and also get information from handle. The Voice Control API also notifies you (by callback mechanism) when the states of client and service are changed, command is recognized, current language is changed or error occurred. An application should register callback functions: vc_state_changed_cb(), vc_service_state_changed_cb(), vc_mgr_all_result_cb(), vc_mgr_pre_result_cb(), vc_result_cb(), vc_mgr_begin_speech_detected_cb(), vc_current_language_changed_cb(), vc_error_cb(), vc_mgr_dialog_request_cb(), vc_mgr_private_data_set_cb(), vc_mgr_private_data_requested_cb().
