Hier ist eine Liste von Befehlen, mit welchen man die Einstellungen ändern kann, z.B. die Sprache (Englisch / Spanisch), Stimme, Lautstärke usw.: [[http://bradsduino.blogspot.de/2013/04/emic-2-text-to-speech-module-arduino-due.html]]. Ein Beispiel, wie man die Lautstärke mit solchen Befehlen ändert, ist bereits im Code oben erhalten. Die Sprache kann man z.B. so ändern:
emicSerial.print("L2"); // fuer lateinamerikanisches Spanisch
emicSerial.print('\n');
===== Alternative: Talkie-Bibliothek=====
Mit der Talkie-Bibiliothek kann man Sprachausgabe machen, ohne einen speziellen Modul, nur mit einem Lautsprecher und Verstärker. Hier ist ein [[https://github.com/going-digital/Talkie|Link]] zur Bibliothek mit Installationsanweisungen. [[http://blog.circuits4you.com/2016/04/text-to-speech-on-arduino.html|Hier]] und [[https://circuitdigest.com/electronic-circuits/small-loudspeaker-circuit-diagram|hier]] wird erklärt, wie man die Schaltung aufbaut.
Die "vorgefertigten" Vokabeln sind in der englischen Sprache verfügbar. Theoretisch kann man eigene Vokabeln zusammenstellen, ist aber mit Aufwand verbunden.
