Text-to-Speech (TTS), otherwise known as speech synthesis, is used in many IVR applications to present information to callers using an artificially produced human voice. TTS is great for concatenating information stored in a database, thus providing ever-changing data to callers like account balance, stock quotes, travel information, alerts and notifications.
Customers always ask us which TTS engine is best. The providers of TTS engines support a variety of voices and languages. These TTS engines even pronounce some words differently. Because TTS engines vary, there seems to be a lack of consensus about which engine is truly the best. That’s why the Plum IVR Hosting Suite supports engines from three different providers: Nuance, AT&T and Cepstral. Below are links to each of the engines’ interactive demos. Feel free to try them out and decide for yourself.
