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

You can use the following text input 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.

• 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.

• 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 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.
