Mobile voice assistants are becoming increasingly prevalent—including familiar names like Google Assistant, Siri and Alexa. Some platforms allow you to add your own voice skills that perform any kind of custom actions. But, there are a lot of restrictions that go along with building into those ecosystems.

For example, you have to find a unique activation phrase for your skill even if it only opens your garage doors. And you have to publish your voice skill to the skills marketplace, diving into the complicated administrative process from platform vendors like Google or Amazon. You can easily build your own mobile voice assistant with only the voice features you really want. First, the user clicks the mic button and speaks a phrase.

A speech-to-text component recognises the speech and converts it to text. Once an intent has been recognised, an action could be performed like opening a garage door.

Implementing all of these steps and components from scratch can eat up a lot of time, even if you have the programming skills. With Rasa and the Aimybox SDK, it becomes much easier to achieve all of these features with minimal effort. Moodbot is a boilerplate application that includes the basic file structure for a Rasa assistant. Here are the steps to install Rasa on your local machine and create the moodbot project. To do this, run the rasa run command in the terminal.

Ngrok generates a temporary tunnel URL for a process running locally, which allows you to publish any local service to the internet, making it accessible from any point in the world. Download ngrok and run ngrok http in a new terminal window to generate a public URL pointing to your local Rasa server, which is running on port A channel is essentially a messaging client where users interface with your assistant. It could be Slack, Facebook, a chat interface embedded on a website, or a voice assistant framework like Aimybox.

The webhook payload sent from the custom messaging channel to this endpoint should contain the identity of the user and their message. This publicly accessible webhook endpoint is all that we need to connect our voice assistant to the Rasa project. Note: Aimybox makes it possible to assemble a mobile voice assistant with any NLU engine as well as speech-to-text and text-to-speech components. After a few moments your Android project will be ready.

Next, we need to connect it to our Rasa server. Within the app folder, locate the build. Add this line just after implementation "com. The only thing left is to build and run your assistant on an Android device. Connect your Android device to your local machine using a USB cable and click on the green play button in the Android Studio toolbar. Here is a great guide on how to do this. Tap on it, and a voice assistant UI appears with a welcome message. Say hello to start a conversation with your Rasa project.

This tutorial uses the Android built-in speech-to-text and text-to-speech engines. We now have a working mobile voice assistant for Android connected to our Rasa server, which implements the voice features we need. But Rasa and Aimybox are both open solutions, meaning we can modify anything we want to make it more personalised. To add buttons, open the domain. Stop the Rasa server by running Ctrl-C in the terminal window and then run the rasa train command.I was learning PHP back then, where I was taught to write codes that combine both front-end presentation and back-end logic together in the same code base.

It was simple, sweet, quick to implement and no issues until I stumbled across a fairly complicated project, where the front-end is so complex that I have to separate it with the back-end in order to keep my head on it.

I started to research on frameworks and tools that can help me in achieving the separation of front-end and back-end development. Microframework refers to a light-weight web application framework in contrast to full-stack frameworks. That means Flask gives only what you need essentially to create a back-end server but provides the flexibility to install any extensions to support features like database interfacing, authentication, encryption, CSRF protection and so on.

Install one of these API testing tool:. Next, we will create a lists of users using Python data structures which are lists and dictionaries to simulate a data store:. Note: This method is used since this article is focusing in creating API, but in actual condition, the data store is usually a database. Now we will begin creating our API endpoints by defining a User resource class. Four functions which correspond to four HTTP request method will be defined and implemented:.

The get method is used to retrieve a particular user details by specifying the name:. We will traverse through our users list to search for the user, if the name specified matched with one of the user in users list, we will return the user, along with OKelse return a user not found message with Not Found.

The post method is used to create a new user:. We will create a parser by using reqparse we imported earlier, add the age and occupation arguments to the parser, then store the parsed arguments in a variable, args the arguments will come from request body in the form of form-data, JSON or XML. If a user with same name already exists, the API will return a message along with Bad Requestelse we will create the user by appending it to users list and return the user along with Created.

The put method is used to update details of user, or create a new one if it is not existed yet. The delete method is used to delete user that is no longer relevant:. By specifying users as a variable in global scope, we update the users list using list comprehension to create a list without the name specified simulating deletethen return a message along with OK. Finally, we have done implementing all the methods in our User resource, we will add the resource to our API and specify its route, then run our Flask application:.

To specify Flask to run in debug mode enables it to reload automatically when code is updated and give us helpful warning messages if something went wrong. It is useful in development setting, but should never be used in production setting. Save the file as app.

The complete code is available here. Your encouragement will definitely be my motivation to write more article or tutorial like this.

We managed seven hot bathing experiences and only had to pay for two of them. The Hotels were excellent - very friendly people too, and we managed to see the northern lights at one of them at 1. The overall organisation of train and boat travel was excellent. All bookings for hotels were accurate and instructions to find the hotels were easily followed. Breakfasts were very good. A well organised experience, which, because we had limited time, provided us with an itinerary that met our needs and gave us time to explore the destinations at our leisure.

Our trip could not have been any better thanks to you and your services. Sara was excellent in helping us to complete our trip.

Also we made a mistake in our days and we needed 2 extra nights stay and they were taken care of right away and were excellent hotels. Your choice of hotels could not have been any better. We will be meeting with a friend here that has a travel agency and will be telling her about you and your wonderful service. Thank you for making our trip so enjoyable. There are so many positives that I just done know where to start, brilliant service from day one, we are looking at coming back and booking with you to do all the bits we couldn't get round to.

We had a great trip and were extremely impressed with the service we received from Nordic Visitor. The level of detail we were given to help us with the trip was excellent.

Build contextual assistants that really help customers

All the hotels were of a very high standard. We will definitely use Nordic Visitor again for any trips to the Nordics. Sigfus provided excellent services and even met with us on our first day in Iceland.

Our trip to Iceland with Nordic Visitor met all our expectations. We had a wonderful trip, due in large part to the maps and suggestions provided in our materials. Both the tour and the extra services we booked were well organised and thoroughly enjoyable. The mobile phone was a very thoughtful inclusion, and allowed us to (for example) easily call a taxi after we dropped off the rental car - very welcome on a cold night.We have fallen in love with Iceland. It was reassuring to know that help, if needed, was available from the very friendly Nordic Visitor office.

The mobile phone which was provided was a nice touch. Food was of a very high standard. Icelanders are extremely friendly. Yes, the rather shy Northern Lights did make an appearance. A real "WOW" holiday!!. Last minute changes to the hotel bookings were dealt with extremely efficiently. Nordic Visitor were very helpful during the duration of the whole tour. I would like to say that Thordis was particularly helpful when I experienced difficulties after being caught in a snow blizzard and became trapped in my vehicle.

The back up service an support was excellent and helped me greatly during a difficult time. I really enjoyed it. It gave me a great taste of Iceland and took away all the hassle of searching for tours and accommodation which is important for me because I have limited free time since I work 80-100 hour weeks.

It took me to places in Iceland I may not have considered if I booked on my own. Even though we travel to Europe at least a couple of times a year and do it indepently (find our own accomodation, etc.

Iceland's reputation of being very expensive concerned us too. We pinpointed the potential travel time as early September (2012), during the summer, we started to search more intensely. Tried to compare and understand the kinds and details of services offered by a number of different operators.

Self-drive tours appealed to us since we would be still independent but especially accommodations would be arranged for us. Small towns with potentially limited accomodations and the distance in between did not give a comfort level for arranging our own accomodations.
