WatchKit: Speech to text conversion in WatchKit Apps

Question

Can any one help me with a sample code for adding Speech to Text conversion feature in Apple Watchkit apps.

Answer 1

Yes, it's possible. Here is the documentation: https://developer.apple.com/library/prerelease/ios/documentation/WatchKit/Reference/WKInterfaceController_class/index.html#//apple_ref/occ/instm/WKInterfaceController/presentTextInputControllerWithSuggestions:allowedInputMode:completion:

The code look like this. You provide a suggestions array with words (or emoji too) and you set the allowed input mode that can accept animated emoji, emoji or plan text only.

[self presentTextInputControllerWithSuggestions:@[@"hello", @"world"] allowedInputMode:WKTextInputModePlain completion:^(NSArray *results) {
    NSLog(@"results: %@", results);
}];

The result is this:

Answer 2

You can ask for user input and give him suggestion (see Swift example bellow).

self.presentTextInputControllerWithSuggestions(["suggestion 1", "suggestion 2"] allowedInputMode: .Plain, completion: { (answers) -> Void in
    if reply && reply.count > 0 {
        if let answer = answers[0] as? String {
            println("\answer")
        }
    }
})

If suggestion is nil it goes directly to dictation. It is not working on the simulator but it is on real watch.
