I have chat bot developed using Microsoft bot frame work in , in chat bot we have a option for customer to ask a question for that we need to make it voice enabled as of now we are using node.js and azure for development . i wanted to know how we can achieve it ?
On google chrome, mic can be enabled easily. Google chrome will also translate the voice for you. First follow below link, see if you are using same framework : https://learn.microsoft.com/en-us/azure/bot-service/bot-service-channel-connect-webchat-speech?view=azure-bot-service-3.0
Post that following link can also help enabling the voice. Can't Chrome's speechSynthesis work offline?
You can enable voice on Firefox as well using bing translate. This link will help you: https://github.com/Microsoft/BotFramework-WebChat/issues/1141
