Now Alexa’s voice apps don’t have to sound like Alexa. Amazon today is offering a way for developers to give their voice apps a unique character with the launch of eight free voices to use in skills, courtesy of the Amazon Polly service. The voices are only available in U.S. English, and include a mix of both male and female, according to Amazon Polly’s website.
Amazon Polly was first introduced at Amazon’s re:Invent developer event in November 2016, and has been steadily ramping up its capabilities in the time since. The text-to-speech service today is capable of things like whispering, speech marks, using a timbre effect, and dynamic range compression – all which make the voices sound more natural.
While the speech engine today supports a couple dozen languages, only the U.S. English voices are being offered to Alexa developers at this time.
But their addition could make some of Alexa’s skills more engaging – especially those involving different characters, like an adventure story or game, for example.
