For developers with skills that use only one voice, changing it or adding another in the right place may offer a more engaging experience for customers, according to the post.
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.
Way back in January 2017 at CES 2017 BMW and Nissan announced that the companies would be bringing Microsoft's Cortana to your vehicle as part of its Connected auto vision. Visit the Amazon Polly product page for more information.
Developers today may already be using multiple voices in their skills, but the process of doing so is more cumbersome and rigid, as with mp3 file uploads.
"Using Amazon Polly, you can choose a different voice for any utterance by using the Structured Speech Markup Language (SSML) and specifying an Amazon Polly voice using the "voice name" tag", the post stated. It's as easy as that.
Amazon announced a developer preview for adding eight Amazon Polly voices to Alexa skills.
At the event, Vogels said: "We've been thinking if voice is the natural way to interact in your home and home automation, why don't we build something you can use at work as well?" We'll select a subset of the skills that apply, and will provide more information to those selected.
The eight voices will be in US English and will give devs who use them a chance to liven up their Alexa skills.
