Here is the fragement code :

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_home, container, false);


        editText = v.findViewById(R.id.editText);

        toSpeech = new TextToSpeech(HomeFragment.this, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    Locale locale = new Locale("tr-TR");
                    int result = toSpeech.setLanguage(locale);
                } else {
                    Toast.makeText(getApplicationContext(), "Not Supported", Toast.LENGTH_SHORT).show(); 
                }
            }
        });


        return v;
    }

    public void TTS(View view) {
        switch (view.getId()) {
            case R.id.bplay:
                if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                } else {
                    text = editText.getText().toString();
                    toSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
                    toSpeech.setSpeechRate((float) 0.8);
                    toSpeech.setPitch((float) 0.7);

                }
                break;
        }
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        if (toSpeech != null) ;
        {
            assert toSpeech != null;
            toSpeech.stop();
            toSpeech.shutdown();
        }

    }

}

Answer 1

new TextToSpeech(HomeFragment.this

You should use getActivity() .

Return the FragmentActivity this fragment is currently associated with.

Toast.makeText(getActivity(), "Not Supported", Toast.LENGTH_SHORT).show(); 
new TextToSpeech(getActivity()

Finally

toSpeech = new TextToSpeech(getActivity(), new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                Locale locale = new Locale("tr-TR");
                int result = toSpeech.setLanguage(locale);
            } else {
                Toast.makeText(getActivity(), "Not Supported", Toast.LENGTH_SHORT).show(); 
            }
        }
    });

Answer 2

First of all,

In your code you have given HomeFragment.this which is not proper in fragment.

toSpeech = new TextToSpeech(**HomeFragment.this**, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    Locale locale = new Locale("tr-TR");
                    int result = toSpeech.setLanguage(locale);
                } else {
                    Toast.makeText(getApplicationContext(), "Not Supported", Toast.LENGTH_SHORT).show(); 
                }
            }
        });

You need to change HomeFragment.this with getActivity() and also change getApplicationContext() with getActivity() in your code like below : -

toSpeech = new TextToSpeech(getActivity(), new TextToSpeech.OnInitListener() {
                @Override
                public void onInit(int status) {
                    if (status == TextToSpeech.SUCCESS) {
                        Locale locale = new Locale("tr-TR");
                        int result = toSpeech.setLanguage(locale);
                    } else {
                        Toast.makeText(getActivity(), "Not Supported", Toast.LENGTH_SHORT).show(); 
                    }
                }
            });

Second Option

If in case still Toast is not working properly using getActivity() then you can also try

getActivity().getBaseContext();

like below:-

Toast.makeText(getActivity().getBaseContext(), "Not Supported", Toast.LENGTH_SHORT).show();
