why is TTS's synthesisToFile taking forever to save a string to .wav?

I am trying to save a huge string(book pages) to .wav files using synthesisToFile, problem is it is taking 11 years to save the complete file. I even broke it up into paragraphs but still no luck-

 ///

    Pattern re = Pattern.compile("[^.!?\s][^.!?]*(?:[.!?](?!['"]?\s|$)[^.!?]*)*[.!?]?['"]?(?=\s|$)", Pattern.MULTILINE | Pattern.COMMENTS);

    Matcher reMatcher = re.matcher(charSequence);

    /////

    int position = 0;

    int sizeOfChar = charSequence.length();

    String testStri = charSequence.substring(position, sizeOfChar);

    while (reMatcher.find()) {

        String temp = "";

        try { // speak

            temp = testStri.substring(charSequence.lastIndexOf(reMatcher.group()), charSequence.indexOf(reMatcher.group()) + reMatcher.group().length());

            // save to wav

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

                File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);

                textToSpeech.synthesizeToFile(temp, null, new File(String.valueOf(path) + "/mm.mp3"), "speak");

            }

        } catch (Exception e) {

            // error

            break;

        }

    }

I just checked the generated file size in my file explorer app, after it reaches a certain size (1.6mb) it stops increasing in size. This method is useless
