Hello, Welcome to our Microsoft Q&A platform! TextToSpeech class enables an application to utilize the built-in text-to-speech engines to speak back text from the device. If you do not use the Google play services, it will use built-in text-to-speech engines to speak it, I test with Huawei android device with await TextToSpeech.SpeakAsync("Hello World"); it worked as normal.

I add a break point in the var locale = locales.ElementAt<Locale>(37), I found the number 37 is ”中文“, I used it, it can read the "百度一下".

var locales = await TextToSpeech.GetLocalesAsync(); // Grab the first locale var locale = locales.ElementAt<Locale>(37); var settings = new SpeechOptions() { Volume = .75f, Pitch = 1.0f, Locale = locale }; await TextToSpeech.SpeakAsync("百度一下", settings);
