Background

Through the research on understanding KaiOS users, we learned that some users prefer voice search over typing as a way to search for information on their phones. This spike task is to help us identify:

1. What Indic languages the Jio voice API supports
2. How it works
3. How to integrate it
4. Identify integration risks

Results

Jio confirmed there is no Voice API for us to use but they are working on it.

On non-Jio devices, the Google assistant can be used to search (long press on CSK) in the app. On Jio devices, the Google assistant is present but seems to be only integrated on Google apps (youtube, maps).

The Web Speech API can be enabled using the speech-recognition permission in the manifest. Here's an example on how to use it:

var recognition = new SpeechRecognition();
recognition.continuous = false;
recognition.lang = 'en-US';
recognition.interimResults = false;
recognition.maxAlternatives = 1;
recognition.onresult = event => { /* do something with event.results[0][0].transcript */};
recognition.start(); // listening now
