This sample channel demonstrates how to create and configure dynamic voice-enabled keyboards. The sample channel includes a voice-enabled keyboard, PIN pad, mini-keyboard, and custom keyboard (an address keyboard form).
Developers can upgrade the legacy keyboards, mini keyboards, and PIN pads in their channels to include voice entry in English and text entry in multiple languages. The new dynamic voice-enabled keyboards enable customers to, for example, speak their passwords when logging in, which helps reduce friction. Other benefits include localized in-channel search and localized customer information entry.
To run this sample channel, follow these steps:
-
Download and extract the sample channel.
-
Follow the steps in Development environment setup to enable developer mode on your device, archive the files, and then sideload the archive to your Roku device.
-
In the UI of the sample channel, select a keyboard from the list.
The DynamicKeyboard nodes combine DynamicKeyGrid and VoiceTextEditBox nodes to provide a single node that supports text entry in multiple languages and voice entry in English.
-
The DynamicKeyGrid provides keyboard functionality. The layout of the keyboard is based on a JSON-formatted Key Definition File.
The classes derived from DynamicKeyboardBase (DynamicKeyboard, DynamicPinPad, and DynamicMiniKeyboard) have built-in Key Definition Files. For example, the DynamicKeyboard node uses a Key Definition File that matches the key layout of the legacy Keyboard node.
The DynamicCustomKeyboard node enables developers to define a custom Key Definition File in order to configure the key layout. In the Key Definition File, the developer specifies the keys in each section and row of the keyboard. The keys support the characters in the Basic Latin, Latin 1 Supplement, Latin Extended-A, and Latin Extended-B blocks. This provides support for most Western European languages, including English, French, German, Italian, Portuguese, and Spanish.
-
The VoiceTextEditBox displays the text that has been entered or spoken. This node supports multiple voice entry modes for entering email addresses, passwords, street addresses, and PINs. This node currently supports voice entry in English only.
Developers should upgrade the legacy keyboards in their channels to dynamic voice-enabled keyboards in order to leverage the following benefits:
-
Faster on-device sign-ups and sign-ins. Enable customers to use voice entry to provide PIN codes when subscribing to channels and passwords when logging in.
-
Localized in-channel search: Enable customers to search for content in their native language.
-
Localized customer information entry: Enable customers to enter their personal information in their native language.
