Text Input, Gesture and Voice

The text input, gesture and voice features introduce how you can convert speech to text and back to speech, and provide recognized gestures, customized keyboards and voice control, and retrieve previous data in a text input field.

You can use the following text input, gesture and voice features in your native applications:

  • Input Method

    You can create an Input Method Editor (IME) application that provides a customized keyboard for the user. You can show and hide the keyboard as needed, and offer a keyboard option menu to allow the user to manage the keyboard settings.

  • Autofill

    You can retrieve the previously entered data stored in an autofill service.

  • Autofill Service

    You can create an autofill service application that saves and provides the data previously entered by the user.

  • Autofill Manager

    You can create an Autofill manager application that shows installed Autofill service and switches to the selected Autofill service.

  • Gesture in wearable applications only

    You can recognize hand gestures from input sensor data.

  • Speech-to-text

    You can recognize sound data recorded by the user and send the result as text. The result text can, for example, be displayed on the screen.

  • Text-to-speech

    You can synthesize text into sound data as utterances and play it. You can also control the playback by pausing, resuming, and stopping it, as needed.

  • Text-to-speech Engine

    You can implement Text-to-speech (TTS) engine service application to synthesize text into sound data and send the synthesized sound data to TTS framework.

  • Voice Control

    You can allow the user to control the device through voice commands. You can register voice commands, which trigger a callback when the user speaks them. Voice commands registered for EFL-supported UI components can be used to perform component-related actions, such as button clicks.

  • Voice Control Manager

    You can record voice and get responses for the recognized voice commands. You can register general and system voice commands such as “power on”, “power off”, “music play”, “music stop”, and so on. In addition, you can start and stop voice recording.

  • Voice Control Engine

    You can manage Voice-Control-Engine (VCE) service application and control the recorded audio. The result of audio recording is sent as a predefined command.

  • Multi-assistant

    You can create a voice assistant application that can be used in conjunction with other voice assistants on the same machine.
