Simple tips for better text to speech

Posted on January 27, 2011 by Adam Kalsey

Are you looking for a way for your text to speech to sound more natural? Here’s a couple of quick tips.

First, make sure you’re using the right voice. Trying to pronounce Spanish words with an English or German text to speech voice will give poor results. The text to speech engine will phonetically say words it doesn’t know, leading to some odd-sounding vocalizations if you use the wrong language’s voice. See the voice parameter on the say() function for details on how to set the right language. You can also set the voice on ask() and record().

For English speakers, try using a different accent. Tropo provides both US and UK accents. Users in the US find that the British accented voices sound more natural. UK users tend to like the US voices better. Hearing a different accent helps mask the robotic sound of the automated voices.

Play around with our different voices for your application and see what sounds best to you.
