"Not only is TalkTo an incredibly flexible audio front end offered for Alexa Voice Service, our qualification by Amazon means that device manufacturers and audio dev teams can greatly accelerate their development cycles. We look forward to seeing how product makers will use it to accelerate the deployment of Alexa-enabled devices in a variety of end products."
