Web Wake Word Detection / Keywords Detection by Davoice

By DaVoice.io email: ofer@davoice.io

Welcome to Davoice Wake Words – the premier Wake Words / keyword detection solution designed by DaVoice.io.

About this package:

This is a "wake word" package for React.js, Javascript, Angular, Vue.js, Svelte, Next.js, Nuxt.js, Gatsby, Ember.js, Backbone.js and Mithril.js. A wake word is a keyword that activates your device, like "Hey Siri" or "OK Google". "Wake Word" is also known as "keyword detection", "Phrase Recognition", "Phrase Spotting", “Voice triggered”, “hot word”, “trigger word”

It also provide Speech to Intent. Speech to Intent refers to the ability to recognize a spoken word or phrase and directly associate it with a specific action or operation within an application. Unlike a "wake word", which typically serves to activate or wake up the application, Speech to Intent goes further by enabling complex interactions and functionalities based on the recognized intent behind the speech.

For example, a wake word like "Hey App" might activate the application, while Speech to Intent could process a phrase like "Play my favorite song" or "Order a coffee" to execute corresponding tasks within the app. Speech to Intent is often triggered after a wake word activates the app, making it a key component of more advanced voice-controlled applications. This layered approach allows for seamless and intuitive voice-driven user experiences.

http-server . -p 8080 --ssl --cert cert.pem --key key.pem

or "npm run start"

If you do not have cert.pem and/or key.pem: you can create them as follow:

nopenssl genrsa -out key.pem 2048

nopenssl req -new -key key.pem -out csr.pem

nopenssl x509 -req -days 365 -in csr.pem -signkey key.pem -out cert.pem
