Punctuation is not respected on Android

[Jankaz2]

As title says, punctuation is not respected on android devices no matter what Android device and version I use.
Android's docs say that Depending on the recognizer implementation, this value may have no effect. but actually I cannot find any device on which this works. However on iOS it works perfect.

Even the demo video in README.md shows that punctuation is not respected on Android device.

Maybe you know some workarounds or fixes?

My settings are like following

    const [settings, _] = useState<ExpoSpeechRecognitionOptions>({
        lang: languageToCode(lang! as Language) ?? 'en-NZ',
        interimResults: true,
        maxAlternatives: 3,
        continuous: true,
        requiresOnDeviceRecognition: false,
        addsPunctuation: true,
        androidIntentOptions: {
            EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS: 10000,
            EXTRA_HIDE_PARTIAL_TRAILING_PUNCTUATION: true
        },
    });

Hey @Jankaz2, the punctuation feature for Android seems to only be supported on Android 13+ with on-device recognition enabled (i.e. using the com.google.android.as package or enabling requiresOnDeviceRecognition)

There's a few options you can do, including:

• Calling getSupportedLocales() to check what locales the user has installed on their device, and
• androidTriggerOfflineModelDownload() to prompt the user to download the specific locale if necessary

Here's a test on an Android 14 device with on-device speech recognition enabled:
