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.
Amazon Polly is a service that turns text into lifelike speech, allowing developers to create apps that talk - or some other speech-enabled product. With voice becoming a more popular input, businesses can use Polly to differentiate their offerings on Alexa. This new capability can help you enrich your skill's experience, making it more engaging for customers. Now, developers can leverage Polly to add additional natural-sounding voices to their skills.
Polly's voices are far from flawless, of course, but as they see more use, that could change.
Amazon began a push for the use of Alexa in the workplace previous year, launching its Alexa for Business service at the Amazon Web Services (AWS) Re:Invent partner and user conference in Las Vegas. "You can even use an Amazon Polly voice for every utterance in your skill if you like". Amazon Polly can generate speech in dozens of languages, making it easy to add speech to applications with a global audience, such as RSS feeds, websites, or videos. Chiefly, it's the text-to-speech service which helps create the scripts for Alexa skills.
